Abstract

 

The present thesis, adopting a poststructuralist approach, studies the narrative in Trout Fishing in America and In Watermelon Sugar, two novels by Richard Brautigan. The study benefits from deconstructive reading as one of the main foundations of poststructuralist narratology. Displaying deconstruction of important binary oppositions in these two narratives was the main concern of the thesis. The body of the thesis, chapter three and four, each is specified to the study of one of these two binaries. In chapter three, binary opposition of reality/fictionality is studied and the researcher shows how the boundary between these two is blurred. Language is also another tool through which the said binary is challenged. Chapter four studies the binary of past/present and includes subtitles such as narrative time, parody and binary opposition of presence/absence. Parodying particular genre or particular concepts is one of the outstanding characteristics of Brautigan’s works which is apparent in these two novels as well. The parodic nature of Trout Fishing in America is shown by pointing to the different references to American history and well known concepts. In In Watermelon Sugar, metanarrative of utopia collapses down and is replaced with the narratives, each capable of suggesting new definitions for utopia. Deconstruction of this metanarrative, rooted in history, literature and religion, is produced by deconstruction of another binary opposition that is presence/absence. The act of giving voice to the silent narrative or narratives within the text, as well as paying attention to the absent narrators releases the text from the dominancy of the present narrative and makes the hidden or silent narratives emerge.

CHAPTER ONE

 

INTRODUCTION

 

1.  General Background

American literature is indebted a great deal to the Beat Generation. In fact the shift towards the postmodern fiction and poetry wasn’t possible if it were not for the Beat Generation writers. Richard Brautigan is always considered as a writer emerging from this generation. Although he never committed himself to any label or literary movement, his writings is always considered as good examples of the American novel at the period. This thesis is going to analyze two of the early and most important novels of Brautigan.

Richard Brautigan is the author of ten novels, nine volumes of poetry and a collection of short stories. According to Companion to the American Novel he is best remembered for Trout Fishing in America which is considered as “a novel that revolutionized postmodern fiction and may becompared today to works of his contemporary, Ken Kesey, and viewed as the precursor to such younger writers as Tom Robbins” (176).

According to the same source, “Brautigan was born on January 20, 1935, in Tacoma, Washington, to Mary Lula Brautigan; apparently he never met his father, Bernard F. Brautigan, and his mother reportedly also abandoned her children from time to time”(176). At the age of 21 and after being hospitalized as a paranoid schizophrenic, he left Tacoma for San Francisco and met with Lawrence Ferlinghetti who ran a bookstore and small publisher house named City Lights. This bookstore was a gathering place for young poets and writers like Jack Kerouac and William S. Burroughs and Brautigan was soon get influenced by their radical views about literature. The first novel he wrote was Trout Fishing in America but the first novel that was published by him was named A Confederate General from Big Sur (1965). Trout Fishing in America hadn’t been published sooner than two years later in 1967 but when it was released its sudden success among the young American readers was almost a legend. From that time on Brautigan was appreciated by his young readers for his revolutionary style but the critical success didn’t come to him till his death. This American writer committed suicide in 1984 at the age of forty-nine. It was only in late 80s that the literary critics came to conclusion about his works and labeled them as good examples of early postmodern metafiction and cross–genre works. As mentioned above, Brautigan indebted much of his fame to The Beat Generation, a generation which Random House Dictionary, quoting Jack Kerouac, defines in this way: “those who were raised among the Second World War, those who probably due to the influence of the cold war had the tendency to habits and a desire for getting rid of social and sexual tensions”. So it would be useful to follow this movement from a closer view.

 

1.1 Beat Generation

The Beat Generation is a term coined first by an American journalist named Holmes. He was a friend of Kerouac and after reviewing his friend’s ideas published an article in The New York Times Magazine and introduced the term as a label for the young generation emerging from the post-war era in 1952. The term refers to a social life style inspired by careless living and drug addiction which was proper at the time and was a source of inspiration for a few young writers and poets that later were labeled as “beatniks”. These writers had a central group including three major writers, Alain Ginsberg, Jack Kerouac and William. S. Burroughs. Their main attitude in literature was rejection of fixed mainstream literary works as well as the American values in post-war era. They had been inspired a lot by the free life style of ordinary youth along with some effects from experimentation with drugs and an interest in Eastern spirituality. Jamie Russell in The Beat Generation writes:

The Beat phenomenon transformed American society. Not only was it the first expression of what we would now dub youth culture—paving the way for the hippies, punks, grungers and ravers as well as a thousand and one other styles—but it was also the first moment in Western culture when literature, music and film became cool. In other words, it was totally opposed to the boring adult world of work, money and responsibility. (7)

پایان نامه ارشد: بررسی اثر پخت و زمان نگهداری بر میزان نمک‌های نیترات، نیتریت و آسکوربات سبزیجات غده‌ای
ارسال شده در 25 دی 1399 توسط نجفی زهرا در بدون موضوع

همگام با افزایش جمعیت، میزان تقاضای مواد غذایی نیز افزایش یافته و همین امر سبب استفاده بی رویه از کودهای شیمیایی و آلی جهت افزایش تولید محصول شده است (اردکانی و همکاران، ٢٠٠٥). سبزیجات سرشار از ویتامین، مواد معدنی و ترکیبات آنتی اکسیدان بوده که خواص ضد سرطانی آن به اثبات رسیده و سبب کاهش بیماریهای قلبی و عروقی می‌گردد؛ لذا اطمینان از سلامتی این ماده غذایی ارزشمند در جهت حفظ سلامت عمومی جامعه از اهمیت بسیاری برخوردار می‌باشد (الکساندر، ٢٠٠٨[1]؛ اردکانی و همکاران، ٢٠٠٥). مصرف بیش از حد کودهای نیتروژنه، موجبات جذب فراوان نیترات توسط گیاه را فراهم نموده و در این بین، سبزیجات مهم ترین منبع مواجهه محسوب شده که در جذب بیش از ٨٠ درصد نیترات دریافتی سهیم می‌باشد (توروپ کریسنسن[2]، ٢٠٠١).

 

نیترات تجمع یافته در سبزیجات طی یک سری واکنشهای شیمیایی در دستگاه گوارش انسان به نیتریت و نیتروز اسید تبدیل شده و در

 ترکیب با آمینهای نوع اول و دوم، موجبات تشکیل نیتروزآمین که مسبب ایجاد انواع سرطانها (معده، روده، مثانه، دهان)، ناقص الخلقه زایی، بیماری مت هموگلوبینما[3] در کودکان می‌باشد را فراهم می‌آورد (هورد و همکاران[4]، ٢٠٠٩؛ وارزینیاک و سزپانسکا[5]، ٢٠٠٨؛ توروپ کریسنسن، ٢٠٠١).

 

در انسان نیترات به سرعت از معده و ابتدای روده کوچک جذب شده و حداقل ٢٥ درصد آن به بزاق منتقل می‌شود. طوری که غلظت آن در بزاق ١٠ برابر پلاسما است. در افراد بزرگسال ٥ الی ٧ درصد از کل نیترات وارد شده به بدن به نیتریت تبدیل می‌شود در افراد خردسال و افرادی که به بیماریهای معده مبتلا هستند به دلیل pH پایین تر معده، میزان تبدیل به نیتریت بالاتر است. در افراد بزرگسال آنزیم مت هموگلوبین ردوکتاز تولید می‌شود که این ترکیب را به اکسی هموگلوبین تبدیل می‌کند (الکساندر، ٢٠٠٨).

 

شایان ذکر است که جذب نیترات در سبزیجات مختلف، متفاوت می‌باشد. میزان جذب نیترات توسط گیاه به عوامل گوناگونی از جمله مصرف کودهای ازته به مقدار و دفعات متعدد جهت حاصلخیزی خاک، شرایط رشد، شرایط آب و هوایی، فصل، دما، شدت نور، نحوه کشت (سنتی و گلخانهای)، زمان برداشت، تنش رطوبتی، گونه خاک، شرایط نگه داری محصول و pH، گیاهی، سن گیاه انبارداری پس از برداشت محصول متفاوت می‌باشد (بروجردنیا و همکاران، ٢٠٠٧؛ پاولو و اهالیوتیس[6]، ٢٠٠٧؛ رحمانی، ٢٠٠٦؛ دیک و همکاران[7]، ١٩٩٦؛ هانتر و همکاران[8]، ١٩٨٢).

 

یافته‌های لورنز[9] و براون[10] گویای این مطلب است که تجمع نیترات بسته به نوع سبزیجات و اندام مورد مصرف آن‌ها متفاوت است (لورنز، ١٩٧٨؛ براون، ١٩٦٦). استانداردهای مختلفی در رابطه با حداکثر مجاز نیتریت و نیترات در سبزیجات وجود دارد. در سال ١٩٩٧ برای محدود کردن موانع تجاری در اتحادیه اروپا آیین‌نامه کمیسیون اروپایی (EC) به‌شماره ٩٧/١٩٤ بیشترین سطح نیترات را در بعضی از سبزیجات تنظیم کرد. حدود مجاز بر اساس فصل‌های سال متغیر بوده که بیشترین سطح مجاز نیترات در سبزیجات، فصل زمستان است (کمیسیون کشورهای اروپایی[11]، ١٩٩٧ و ١٩٩٩). در ایران حد مجاز نیترات در سبزیجات مختلف ارائه نشده، اما به طور میانگین حداکثر میزان نیتراتی که روزانه وارد بدن می‌گردد بایستی کمتر از ٦٥/٣ میلی گرم بر کیلوگرم وزن بدن باشد (کمیته‌ی کشورهای اروپایی، ١٩٩٩). با این وجود یک فرد ٧٠ کیلوگرمی نباید بیشتر از ٢٥٥ میلی‌گرم نیترات مصرف نماید. بنابراین باید غلظت نیترات را مخصوصاً برای افرادی که در رژیم غذایی آن‌ها سبزیجات زیاد مصرف می‌شود به حداقل مقدار ممکن کاهش داد (سانتاماریا و همکاران[12]، ١٩٩٩؛ ماینارد و بارکر[13]، ١٩٧٩).

 

تاکنون مطالعات بسیاری در رابطه با وجود نیترات در سبزیجات مختلف صورت گرفته و به نتایج متفاوتی انجامیده است (آرکوت و لی[14]، ٢٠٠٨؛ ولزن و همکاران[15]، ٢٠٠٨؛ آیلین[16]، ٢٠٠٧؛ سبرانک و باکاس[17]، ٢٠٠٧؛ وارزینیاک و کویاتکاسکی[18]، ١٩٩٩). پختن و انجماد از جمله روش‌های نگهداری سبزیجات به شمار آمده که موجب تغییراتی در ترکیب شیمیایی و محتوی نیتریت و نیترات محصول می‌شود (کوروس و همکاران[19]، ٢٠١١؛ پراساد و آوینش چتی[20]، ٢٠٠٨؛ جاورسکا[21]، ٢٠٠٥؛ شیمادا و سانائه[22]، ٢٠٠٤).

 

در پژوهش حاضر، محتوی نیترات، نتیریت و اسید آسکوربیک موجود در ٥ نمونه سبزی (هویج، پیاز، سیب زمینی، ترب، سیر) اندازه گیری شد و اثر زمان نگهداری در یخچال و شرایط نگهداری (خام یا بخارپز) بر میزان این نمک‌ها ارزیابی گردید.

Abstract

 

This research analyzes The Tenants (1971) within the context of ethnocentrism, specifically the segregation between two minority groups of Jews and Blacks in the USA, and the extent to which religion and nationalism, among other factors, have affected their interactions. The novel is a story of two writers, one Jewish, one Afro-American, living in a tenement and how Anti-Black and Anti-Semitic sentiments affect their relationship and their lives within their own community and their interactions with women. Different ideas on discrimination against minorities and xenophobia from racism critics are presented; among them there is a focus on History of the Confrontation, Religion, Nationalism including Jews Assimilation policy, Conceptions of Blacks from Jews and vice versa together with Conceptions of Blacks from Blacks and Jews from Jews and finally the transitory Alliance between the two cultures which are proposed by the civil right activist and critic, Cornel West (1953). There is proof of direct effect of these factors introduced by West on the characters and how these points lead them to choose a different way of overcoming their suppressed past and to avoid remaining the Other. The open-endedness factor of this masterpiece from the beginning to the end of the novel gives a sense of resolution between the two races to the reader.

Introduction

 

1.1. General Background

Bernard Malamud (April 26, 1914 – March 18, 1986), a great prolific American Jewish writer of 20th century, was born into a Russian-Jewish immigrant family. His major concern in most of his works is the problem of the Jews in world and the prevalent racial issues of his era. Professionally speaking, being a Pulitzer Prize for his novel against discriminations on Jews, The Fixer (1966) is one of his life time achievements.

His novels include the tragic-comic element and pessimism that Malamud uses with his unique style of writing, displaying the challenges of modern urban life with focus on marginalized characters who struggle to survive through love and forgiveness rooted in Judeo-Christian beliefs (Pinsker, 205-211). The Tenants (1971) is one of his famous novels which revolves around the Black-Jewish relationship in 20th century USA.

Specifically speaking, The Tenants is the story of two writers, one Jewish and the other Black, about their conflicts and communication in a tenement located in New York with no appropriate conditions for living. The novel opens with Harry Lesser (Jewish writer) having spent nine and half years finishing his book and refusing to leave the tenement belonging to Mr. Levenspiel until his last chapter of the novel is completed.

Lesser is not the only character from a minority group settling that tenement. While he is following his routine life of writing his novel, second character from Black minority appears and from that point on their interaction triggers a latent fear and hatred which come to its zenith in a tragic scene in one of the endings of the novel. In this pathetic scene both writers become victims of each other’s hatred ending up, in one of the endings of the book, killed by one another and Lesser’s ten year manuscript burned by Willie (The black character). And in the other ending, which is a

 happy one and where multiracial marriages take place, a more detailed consideration is required.

Though created by Malamud’s creative and imaginative mind, the dramatic frictions of two main characters throughout the story were the direct reflection of the social and political current salient and challenging in Malamud’s life time. The concepts that are worth consideration in The Tenants are Black Anti-Semitism and Jewish Anti-Black Racism in American Society with its multicultural setting and how the construction of American identity in the modern era for Jews and Blacks is affected by ethnocentrism, religion and the history behind the two cultures. To grasp the inner atmosphere of the story and what had occupied Malamud’s mind, a cursory glance at racism history seems helpful.

Racism and its related movements in USA are well known through the world. The Blacks, the Jews and other minority groups have struggled to make themselves free from the racists’ burdens and this created an atmosphere of alliance and support between minority groups and encouraged the leaders of each minority speak for the right of not only his race but also other minorities. Therefore, it is not strange to hear that Jewish leaders and Black revolutionary vanguards defended each other in the face of White-Christian mainstream. Despite this unity, after 1950s some changes and shifts began to burgeon. The Jews trend in surrendering part of their identity to achieve the mainstream approval was one of the starting points of their difference with the Blacks. They continued to develop socially and economically and even as writers they devoted part of White-American literary canon to themselves and their works found readers among White Christian people. They accepted to obey the grammatical rules defined by mainstream while black writers were completely reluctant to surrender even their writing style.

Quite contrary with the Jews were the Blacks who detested losing their identity in favor of getting the Whites’ admission. Their writers, as mentioned above, continued to follow their own language, style of writing and vocabulary which were different from those of the Whites. Following the story, reader would find the same tendency in Lesser, the Jewish writer, and Willie, the Black writer. Willie is abhorrent to accept the grammatical rules of the mainstream. That is why while reading and revising Willie’s manuscript, Lesser criticizes him for not following the regular writing rules and this shows Lesser’s acceptance of mainstream rules and his idea of Willie’s wrong deed not to obey it.

Not only in writing but also in most of their life affairs, the Blacks continued to ask for their rights. Not accepting the Whites’ norms they remained the others while the Jews came free of being the other. The chains of alliance were broken and these two minority groups stood in two opposite poles and hatred emerged in their daily life interaction. The Tenants is a meticulous observation of these two writers’ reaction to each other and their emotional and psychological response. Willie releases his anger and terror in his innovative writing wherein he kills and even eats the Jews including Lesser several times.

These concepts and Jews and Blacks Nationalism as marginalized figures in America and the relationship between them, have been the subject of interest of many critics; among them the African-American critic Cornel Ronald West’s (1953) ideas are worth consideration. West is a Black-American civil-right activist addressing such issues as multiculturalism, racism, socialism and focusing on African-American studies. He contributed to post-1950s civil right movement and led most of his activities around gender, race, and class in American society and showed his interest in these fields from early youth. West’s school of thought circles around the history of discrimination, the peace moments between two cultures and the roots of hatred in regard to many factors including religion. West calls America a “Racist Patriarchal” (Race Matters, 90) and as he believes in one of his bestselling books, Race Matters (1993) “As long as black people are viewed as a them the burden falls on blacks to do all the cultural and moral work necessary for healthy race relations. The implication is that only certain Americans can define what it means to be American—and the rest must simply fit in” (West, 3).

In West ideas, Black inferiority and self-degradation facing White settlers superiority, undermined their genuine feeling of true citizens, as a result a dormant feeling of fear, fake identity and hatred emerged to define their everyday life. A good example of what West is focusing on is seen in the relationship between two characters in The Tenants. As he indicates, “Recent debates on the state of black-Jewish relations have generated more heat than light. Instead of critical dialogue and respectful exchange, people have witnessed several bouts of vulgar name-calling and self-righteous finger-pointing” (West, Race Matters, 71). The reader faces the same matter at one ending of The Tenants as Willie calls Lesser “Blood suckin Jew Nigger hater” and Lesser calls Willie “Anti-Semitic Ape” (The Tenants, 90).

Reading The Tenants in the light of Cornel West’s ideas makes the researcher interested to appoint them to this novel. What makes this analysis more interesting is the two very different endings of the novel which proposes more questions and more considerations of the two characters’ relationship with one another and with other people in the society.

 

1.2. Statement of the Problem

America is a multicultural country and home of a variety of ethnic groups with different cultures and religions, so it seems that friction and collision between minorities is a common problem there and has been the subject matter of many surveys and novels. The Blacks and the Jews are two groups which have been experiencing this tough situation from 1950s on. It was before 1950s that there was short alliance between the two cultures at the time of The Civil Rights Movements in America toward the freedom for Africans and other marginal figures but the discrimination factor and ethnocentrism has continued to be felt and lived through the stereotypes believed by people up to the present time. What makes the matter even more complex is how the members of each marginal group as Jews and Blacks feel and treat each other, the conceptions they have of one another and the self-degradation beliefs in their relationships.

As the former Harvard lecturer on history and literature, Edmund Spevack (1963-2001), quotes from the African American civil right activist William Edward Burghardt Du Bois (1868-1963) in his essay on “Racism and Multiculturalism in Bernard Malamud’s The Tenants” (1997) “W.E.B. Du Bois warned in 1903 that the main problem of the twentieth century would be the color line; indeed, the burning issues of economic, social, and cultural inequality among racial groups in America were not solved, but became ever more complex and urgent” (Spevack, 33). Besides,  he cites Henry Louis Gates (1950), the African American writer and literary critic in the same essay, “We might as well argue that the problem of the twenty-first century will be the problem of ethnic differences, as these conspire with complex differences in color, gender, and class” (Spevack, 50).

As pointed out before, in the twentieth century and also at the present time, the main problem of such multinational country as America is how to deal with the difficulties and tensions raised between the minorities like those of Black and Jewish people. The world of The Tenants is indicative of this modern social and political phenomenon that has cast a shadow over the life of two main characters, Lesser and Willie, through story. As West indicates in his book Race Matters,

Black anti-Semitism and Jewish anti-black racism are real, and both are as profoundly American as cherry pie. There was no golden age in which blacks and Jews were free of tension and friction. Yet there was a better age when the common histories of oppression and degradation of both groups served as a springboard for genuine empathy and principled alliances. Since the late sixties, black-Jewish relations have reached a nadir (Race Matters, 71).

 

Although  very few and very short, there are moments in the novel when two characters seem friendly and sympathetic toward each other, for example when Willie gives his manuscripts to Lesser to read and revise, or inviting Lesser to the party, when Lesser hides Willie from the owner of the tenement, who is also a Jew, when Willie supports Lesser from the physical attack of his friends and many other instances from novel’s close reading that researcher thinks as likely to be seen in great accordance with Cornel West’s ideas about short alliance.

Apart from the conflicts mentioned previously, Malamud’s style in development of his writing and characters are to be analyzed which includes the clashes between two marginal cultures of Jews and Blacks, the history and roots behind them in the account of Cornel West ideas and how the roots affect the relationship between the two characters in novel The Tenants, the African-American relationship, (or the Black-Jewish relationship, the term used by West), their bigotry toward each other and their hard times living together and with other people in the society are going to be highlighted.

Abstract

Attention to a specific target or location in visual space enhances the baseline activity of the cells representing the target or the spatial location. Attention can also be directed based on the expectations. Attention mediated enhanced baseline activity is correlated with improved object recognition. To explore the relation of visual attention with neural baseline activity, cortical sensory processing and the behavioral choice we recorded the activity of single cells in the inferior temporal cortex of monkeys during two different tasks. The tasks were a passive fixation and a two-alternative forced choice categorization of noisy body and object images. We found enhanced neural activity in categorization task compared to the passive fixation task. Both body and object selective cells showed significantly more response enhancement for their preferred category compared to the non-preferred category. No such response enhancement was observed in trials when the monkeys made a wrong choice in the categorization task. Magnitude of the response enhancement was larger for more noisy stimuli. More importantly, in trials with high baseline activity responses of body selective and object selective cells to body images were enhanced and suppressed, respectively. We also found decreased neural response variability in the categorization compared to the passive task. Larger effects were observed at higher noise levels. By measuring choice probability we found that neural firing rate was correlated with monkeys’ choice, particularly in trials with high baseline activity. We suggest that attentional enhancement of IT cells’ baseline firing rate is correlated with improved neural response reliability and category selectivity. These effects are dependent on the cells’ category selectivity, attentional load and the exact time of baseline activity increase.

Introduction

 

The crucial role of “visual object categorization” in everyday life

Our normal life relies on ability of visual object recognition or determining the identity of a seen object. We recognize different familiar or novel objects in everyday life. We do this with no or little effort, despite the fact that these objects may vary in form, color, illumination, view, size or texture from time to time. Based on both behavioral and neural data there are different levels of object recognition. When we see Einstein’s face, first we detect it as a “face” (supraordinate level), perceive as a “human face” (ordinate level) and then “Einstein’s face” (subordinate level). Spector and Kanwisher explored the sequence of processing steps in object recognition by asking human subjects to do three different tasks: object detection, categorization and identification. Accuracy and reaction time were similar for object detection and categorization showing that “as soon as you know it is there, you know what it is” (Spector and Kanwisher, 2005). On the other hand, lower accuracy and longer reaction time was observed for identification compared to categorization, introducing them as different steps of object recognition. Compatible with behavioral data firing patterns of single cells in inferior temporal cortex, a cortical area involved in object recognition, convey the information about categorization and identification with different latencies. Earliest part of the response (~120 ms after stimulus presentation) represents information about categorization while more detailed information about members of category started ~50 ms later (Sugase et al., 1999). Therefore, visual cortex processes information from global to fine in a hierarchical fashion.  It has been suggested that categorization relies on the “presence or absence of features”, whereas identification is based on “configurational judgments”.

“Visual object categorization” or our ability to classify objects by giving meaning to our environment enables us to interact normally and efficiently with objects and events. There are some defined classes of objects in our mind. They usually share some major common properties in their appearance, while at the same time there are lots of differences among their members. For example, trees usually grow from the earth, they have roots, stem and usually green leaves. While they have similar properties, each of the species has a set of specific characteristics. But we call all of them trees, and also easily classify any new member as tree, even if we have not seen something like it before. This fascinating ability of categorization objects is vital for our survival. We know special traits for different object categories. We have learned how to treat and interact with any of them, depending on their characteristics. For example, classifying a rod-shaped moving object as “snake” makes us to run away as fast as possible. We perform this task easily and rapidly under very different conditions and even in noisy environment. Behavioral studies in human have shown that they can recognize animals in a cluttered picture which is presented only for 20ms with reaction times less than 400ms and 95% accuracy (Thorpe et al., 1996; Keysers et al., 2001). Monkeys showed even faster reaction times (Fabre-Thorpe et al., 1998). Monkeys could categorize food and trees with reaction times less than 250ms (Vogels, 1999a). Single cell studies in macaque inferior temporal (IT) cortex have revealed that category response latency is less than 100ms from stimulus onset (Vogels, 1999b; Kiani et al., 2005; Perrett et al., 1982).

 

Where in the brain is category information represented?

Neural mechanisms of and cortical areas involved in visual object categorization are among the hottest areas in field of cognitive neuroscience. Exploring the underlying mechanisms of visual categorization in the activity of single neurons of a special cortical area is based on what Santiago Ramon Cajal proposed by “Neuron Doctrine” over a century ago. He showed that nervous system is not one continuous web but a network of discrete cells. According to “Neuron Doctrine” individual neurons are the basic structural and functional units of the nervous system. This finding led to a new view of brain function called “Cellular Connectionism”. Based on this view, individual neurons are the signaling units of the brain; they are generally arranged in functional groups and connect to one another in a precise fashion and different behaviors are produced by different brain regions interconnected by specific neural pathways (Kandel, 2000).

Visual cortices are regions of the brain dedicated to the process of visual information. There is a “feed-forward flow of visual information” in these cortical areas. Visual information after reaching the eyes extends from the retina to the primary visual cortex (V1) and then the secondary visual cortex (V2). After V2, visual information goes through two different visual pathways:

  1. Dorsa visual pathway or “what” pathway, involved in motion detection and visumotor tasks
  2. Ventral visual pathway or “where” pathway, involved in object recognition

 

Understanding and recognition of shape of visual objects are completed in ventral visual pathway of the brain. Across the ventral visual pathway, there is a flow of visual information from the lower level visual areas (V1 & V2) into mid level (V4) and then to the high level visual area (IT) (Merigan & Maunsell, 1993). There is also a hierarchical organization even along the subareas of IT cortex. These intrinsic connections in the IT cortex were studied by Fujita & Fujita (1996). They showed that these connections were distributed in an anisotropic manner (fibers go through anteroposterior direction more than mediolateral direction) around the injection of the tracer showing the continuous feed-forward flow of visual information even in these subareas. Along with this feed-forward flow of visual information there is a hierarchical processing of the visual information. Reflected light from visual stimuli after entering the eyes is converted into electrical signals by photoreceptors and ganglion cells in the retina which respond optimally to contrast and small spots of light in their small receptive fields resulting in decomposition of visual stimuli into a pattern of small spots. Progressive convergence of input from retina and LGN (lateral geniculate nucleus) to the primary visual cortex (V1) leads to some feature abstraction. The outline of a visual image is decomposed into spots in retina and then recomposed into short line segments of various orientations by simple and complex cells in V1 cortex (Hubel & Wiesel, 1962). The visual pathway extends from V1 to V2. V2 neurons continue the analysis of contours begun by V1 neurons. Response of many V2 neurons to illusory lines just as real edges shows that the feature abstraction is in progress through the visual stream (Kandel, 2000). To clarify the progressive abstraction of visual information processing from V2 to downstream cortices, Kobatake & Tanaka (1994) defined an index based on the ratio of the maximum neural response to simple stimuli to the maximum neural response to all other stimuli in their image set (both simple and complex stimuli). The distribution of this ratio shifted from 1 toward 0 step by step from V2 to anterior IT. They showed that in macaque monkeys,  the best stimulus of cells in V2 were just simple shapes, in V4 and posterior IT were both simple and complex features and the cells selective to complex features were intermingled in single penetrations with cells that responded maximally to some simple features. They also found that neurons of anterior IT were just selective to complex features. They suggested that local neuronal networks in V4 and posterior IT play an essential role in the abstraction of simple features into complex object features. These findings are consistent with “Feature Detection Theory”, one of the main theories in object recognition. According to this theory, the object perception proceeds by recognizing individual features, such as back, seat, arms and base of a chair, and assembling them into a coherent pattern, or chair.
