Neurogenesis Research Papers Samples For Students

Abstract

The hippocampus is a part of the limbic system found in the temporal lobe. Hippocampal neurogenesis, the ability of the hippocampus to generate/produce new neurons all through to adulthood, has been linked to emotion moderation, spatial navigation, learning, memory, and cognitive function. These functions are usually impaired in depression and anxiety and hence the speculations that hippocampal neurogenesis plays a critical role in the etiology, pathophysiology and even the treatment depression and anxiety. The hippocampal neurogenesis hypothesis attempts to explain the role of hippocampal neurogenesis in the development of depression and anxiety based on findings from various studies. Findings that neurogenesis ...

There was a time when the scientists were of the view that the human brain is of such a nature, that it stops growing and regenerating after the person has lived up to a certain age. So as per this theory, if connections between neurons developed during the first few years of an individual’s life, only the young brain possess the quality of being plastic which is having the ability to form new connections. So if a brain would become damaged, because of this theory, there was belief that it would stop forming new connections and would no ...

Introduction

Memory is the capacity to recall information one has experienced or learned. Many people struggle with remembering events which they have experienced or previously had information on. Students are particularly aware of this fact because they are constantly tested on what they can remember from previous class work. Today, research indicates that there is a noticeable shrink in the hippocampus during late adulthood, which leads to impaired memory, as well as a heightened risk for dementia. However, fitter adults who undertake physical activity have larger medial and hippocampal temporal lobes (der Borght, Havekes, Bos, Eggen, & Zee, 2007). According to Erickson et ...

Pituitary

The different functions performed by the anterior and posterior pituitary in terms of sex
The anterior pituitary which is also known as the adenohypophysis, is basically an interior lobe (glandular) which alongside the posterior pituitary, makes up the pituitary gland. The posterior pituitary releases oxytocin which stimulates and smooth muscle contraction in the mammary glands and the uterus. The anterior pituitary on the other hand stimulates release of thyroid hormones, FSH and LH to stimulate sex cell production and release of sex hormones; it also stimulates sex cell production as well as secretes prolactin to stimulate milk production. ...
