The Genetic Bases Of Learning And Memory - 927 Words

This paper seeks to exploit and explain findings that express the genetic bases of learning and memory. Learning and memory has played a huge evolutionary advantage to animals capable of effectively gathering information of their environment and able to remember and retrieve the information at a different time. The studies covered focused on drosophila because its cognitive functions are very similar to that of higher vertebrates such as humans. The central theme of this paper is to determine the biological bases of learning and memory by observing how disruption of the central nervous system through gene mutations alters the performance of learning and memory thus affecting the organism behavioral responses. A lot of research has been conducted in twin studies seeking to explain why there is a variation in learning abilities between two people of very similar genetic matter. The results of the studies have credited the environment as the major source of the variance but yet not much have been uncovered about how individuals’ genes contribute in playing a role in learning and memory consolidation until recently. Kaminskaya and colleagues knew that actin cytoskeleton remodeling was crucial for learning but they didn’t know what genes led to the remodeling and how that process would eventually affect learning abilities. Lim-Kinase 1 (LIMK1) gene leads to the phosphorylation of CREB 1 which in turn activates genes linked with memory consolidation such as somatostatin.Show MoreRelatedEssay about Huntingtons Disease1557 Words   |  7 PagesHuntington’s Disease is a brain disorder affecting movement, cognition, and emotions (Schoenstadt).

There is an early onset form of Huntington’s disease, beginning in childhood or adolescence, and makes up a small percentage of the Huntington’s population (Sheth). Huntington’s disease is a genetic disorder with a short history, a plethora of symptoms, and devastating consequences, with no current cure in sight.

Alzheimers disease (AD), a form of progressive, irreversible dementia with no known cause or cure, first described in 1906 by Dr. Alois Alzheimer, causes damage to the parts of the brain that control thought, memory and language. The consequences of the disease in terms of the patients lifestyle are often times confused with the natural syndromes of aging. However, AD is not a normal part of aging. The processes which occur in an AD patient are stillRead MoreCognitive Psychology And The Management And Treatment Of Mental Illness1352 Words   |  6 Pagesstructure, chemistry, activity and genetic make-up etc. relates to behaviour. Cognitive psychology focuses on the way the brain processes information, how people perceive, understand, make decisions about and remember information. Cognitive psychologists would put information in to be processed and then see what the brain does with it. To compare the biological psychologist would be looking at the make-up of the brain and seeing how it works that way based on genetics and nature or nurture., whereasRead MoreEssay On ACO851 Words   |  4 Pagesgeneration.

As we previously learned in our textbooks, nature is â€Å"the biological inheritance and nurture to its environmental experiences.† (G-7) Nurture in this case would be learning your knowledge from your parents and being born with intelligence and knowledgeRead MorePhobia Is An Irrational Fear1201 Words   |  5 Pagesclassical conditioning, vicarious acquisition and informational/instructional acquisition (6). Vicarious fear acquisition is to develop fear learning by means of watching others reacting fearfully, for example learning of a child to fear any animal by watching their parent fearing the same animal. They proposed that fears and phobias are primarily due to learning experiences in the environment.
