In other words, performance on the learning tests is associated with neurogenesis. The gene expression measures were taken to aide future research.
The results showed that performance on the learning tests did change, and the hypothesis was proven. Stress from the change, the intermittent pairings, did increase hippocampal neurogenesis in the adult male squirrel monkeys. Learning, especially spatial learning, was enhanced. Moreover, the corresponding gene expressions changed accordingly.
The authors suggest that the results may be generalized to a human population. With special attention paid to human beings suffering from depression, the authors suggest that specially-designed psychotherapeutic interventions for coping with stress will help stimulate hippocampal neurogenesis. Hippocampal neurogenesis is in turn associated with improved cognition. Therefore, effective coping mechanisms are likely to have...
The subjects were 613 injured Army personnel Military Deployment Services TF Report 13 admitted to Walter Reed Army Medical Center from March 2003 to September 2004 who were capable of completing the screening battery. Soldiers were assessed at approximately one month after injury and were reassessed at four and seven months either by telephone interview or upon return to the hospital for outpatient treatment. Two hundred and forty-three soldiers
In Marge's case, we cannot immediately ascertain for certain what biological mechanisms have played a role in her episodic attacks. However, we can deduce that she is vulnerable to the general range of physiological symptoms relating to an anxiety disorder as a result of external triggers which may be socially, domestically or pressure-induced. It is also likely that her increased fear of the recurrence of her anxiety attacks is making
Some treatments may actually help with the disease. Diets and dietary supplements Eating vegetables like broccoli and spinach may help older women [and probably men] retain some memory abilities later on, while avoiding obesity in middle age lowers the risk of later Alzheimer's disease in both sexes, new studies suggest." The effect of the vegetables probably comes from the antioxidants and B. vitamins they contain (Ritter, 2004). Herbal remedies and other dietary
Drug Abuse Drug and substance abuse is one of the most serious dilemmas in the world today. One aspect of the issue is the growing number of teenage drug users and the increasing incidents of prescription drug abuse. According to the statistics of the National Institute on Drug Abuse prescription drugs misuse is far greater than the abuse of narcotics. Among teenagers alone, accepted cases of drug use increased from 27
Aggression from a Heritability Perspective There is a social bias against the idea of aggression, so that many people conflate the ideas of aggression and violence, so that they cannot separate them. This suggests that aggression is negative, which is not necessarily the case. The result has been that suggestions that aggression is somehow genetic have been morphed into the notion that people carrying those genes must somehow be inferior
Figure 1 portrays three of the scenes 20/20 presented March 15, 2010. Figure 1: Heather, Rachel, and Unnamed Girl in 20/20 Program (adapted from Stossel, 2010). Statement of the Problem For any individual, the death of a family member, friend, parent or sibling may often be overwhelming. For adolescents, the death of person close to them may prove much more traumatic as it can disrupt adolescent development. Diana Mahoney (2008), with the
