Neurology and Neurosurgery Essay -- Medical Brain Health Essays

Neurology and Neurosurgery Neurology Overview Although our primary interest is with the Medial Temporal Lobe, also called the V5 area, a discussion of the entire motion perception pathway is instructive. Motion perception actually begins with the specialized visual receptors in the retina known as M-cells (from the Latin word magnus, for large). As the name implies, the M-cells are relatively large, located in the peripheral retina, and respond quickly to transient visual stimulation making them ideally suited for motion detection. By contrast, P-cells are smaller, located in the fovea, react more slowly to stimuli, and are suited to fine-detail vision. Impulses from the retina then travel via the optic nerve to the optic chiasm where fibers of the optic nerve from the inner (nasal) half of each retina cross while those from the outside (temporal) half of each retina stay on the same side. This partial crossing is a feature of mammals, whereas for most vertebrates below mammals, all the fibers cross. It must be pointed out that no motion processing is actually done in the optic chiasm. About 20% of the axons leaving the optic chiasm go to the Superior Colliculus, which is responsible for certain eye movements and spatial localization. The remaining 80% of the axons go to the Lateral Geniculate Nucleus, LGN (Schiffman, 2000, p. 71-73). The LGN represents the next motion processing step after the M-cells in the retina. The Magnocellular Division of the LGN specifically processes the impulses from the M- cells in the retina and is uniquely suited to distinguishing small contrasts between light and dark areas thereby enhancing three-dimensionality and motion ef... ..., J.

Summary The novel’s action begins in Charlie’s thirty-second year in Donner’s Bakery, New York, where he works. Charlie narrates his experience through ‘progress reports,’ which he has to submit to the research team from Beckman College. Charlie is a retarded adult, and he has agreed to submit himself to experimental surgery in order to improve his intelligence. The reports reveal Charlie’s experiences in the bakery to which the owner, his uncle’s friend, has brought him from the Warren State Home for retarded people. Charlie becomes a part of the bakery, and considers the people there as his friends. Yet, he is dissatisfied and wants to be ‘smart.’ So, he joins a special school for retarded people at Beckman College. After this, his teacher, Alice Kinnian, recommends him to a research team at Beckman psychology department. The team is in search of a retarded volunteer, for the experimental surgery to increase intellige nce. Charlie then undergoes weeks of testing and competing with a white mouse, Algernon at completing mazes. He is depressed when the mouse beats him every time. The operation takes place and Charlie is disappointed at not ‘getting smart’ immediately. However, he is assured that he will progress gradually, but steadily. Over a period of time, Charlie finds himself being able to read more, win some mazes and master complex processes at the bakery. The other workers resent him. He is disillusioned with many of them. He has to spend a lot of time reading and being tested at the Beckman lab. By now, he knows that Algernon has also had surgery similar to his, which accounts for his intelligence. Charlie surges ahead in gathering knowledge and mastering languages. He begins to see his supportive teacher Alice, as an attractive young woman. They become close and he tries to make love to her. On several occasions, he finds he has a violent physical reaction when he is making love to her and therefore has to stop. He can’t understand why this happens. Around the same time, Charlie’s repressed memories of his home, surface. Disturbing scenes, like, his mother pushing him to study or others when he is being pushed aside in favor of his younger sister, flash through his memory. Charlie is upset, but he finds his newfound intellectual ability thrilling and works hard. He finds that he and Algernon are to be taken to Chicago for a convention, at which Nemur will present the findings of the team. Once there, Algernon and Charlie are the prime ‘exhibits,’ objects, and humiliating remarks are made in his hearing. He also discovers that the researchers have not given sufficient time to verify their experimental findings before performing the experiment on him. Charlie releases Algernon, and runs away with him to New York. He hides here for some time and rents a house. He understands that his time is short and decides to check the same experiments, in order to trace the reasons for its failure. Charlie gets permission from the sponsors, to work independently on this subject at Beckman. His relationship with Nemur becomes tense and hostile. He can’t overcome his problems with Alice and gets involved with Fay, an unconventional artist living next door. With her, he can defeat his inhibitions. But as his work gets more demanding, their relationship becomes strained and finally breaks. In the meantime, Algernon’s condition gets worse, and he dies. Charlie knows this indicates his own approaching end, and therefore he seeks out his parents. His father is alone in the Browse. Charlie meets him but can’t bear to reveal who he is, for fear of disappointment. His meeting with his mother and sister is anticlimactic, as the mother is old and senile, and his sister is having a bad time coping with the responsibility alone. He is satisfied that he can tell them of his achievements. He makes his peace with them and leaves. He confronts Nemur at a party and charges him of being insensitive. Charlie is also charged of selfishness and arrogance, which he admits is the truth. He accepts that the retarded Charlie is an important and enduring part of him. He and Alice get together but only find fulfillment for a short time. As Charlie’s mind gets worse, he forces her to leave him. He works at the bakery, and when his condition becomes very bad, he moves to the Warren Home.

Essay on Race and Class in Alice Walkers Color Purple

Essay on Race and Class in The Color Purple An important juncture in Alice Walkers The Color Purple is reached when Celie first recovers the missing letters from her long-lost sister Nettie. This discovery not only signals the introduction of a new narrator to this epistolary novel but also begins the transformation of Celie from writer to reader. Indeed, the passage in which Celie struggles to puzzle out the markings on her first envelope from Nettie provides a concrete illustration of both Celies particular horizon of interpretation and Walkers chosen approach to the epistolary form: Saturday morning Shug put Nettie letter in my lap. Little fat queen of England stamps on it, plus stamps that got peanuts,†¦show more content†¦But Walkers privileging of the domestic perspective of her narrators has also been judged to have other effects on the text. Indeed, critics from various aesthetic and political camps have commented on what they perceive as a tension between public and private discourse in the novel.(2) Thus, in analyzing Celies representation of national identity, Lauren Berlant identifies a separation of aesthetic and political discourses in the novel and concludes that Celies narrative ultimately emphasizes individual essence in false opposition to institutional history (868). Revealing a very different political agenda in his attacks on the novels womanist stance, George Stade also points to a tension between personal and public elements in the text when he criticizes the novels narcissism and its championing of domesticity over the public world of masculine power plays (266). Finally, in praising Walkers handling of sexual oppression, Elliott Butler-Evans argues that Celies personal letters serve precisely as a textual strategy by which the larger African-American history, focused on racial conflict and struggle, can be marginalized by its absence from the narration (166).
