The Neuroprotective Effect Of Exercise On Memory Impairment Induced By Stress, Jeff Edwards
The Neuroprotective Effect Of Exercise On Memory Impairment Induced By Stress, Jeff Edwards
Journal of Undergraduate Research
The objectives of this award were met, especially in regard to the mentoring focus of the award. The students have been mentored and trained in an effective manner as outlined in my Mentoring Plan (abbreviated below). This includes mentoring students in research, writing, publishing, presenting at conferences, etc. Indeed, one measure of the success of mentoring is demonstrated by the fact that all the students graduating from my lab during this time were accepted to the professional school of their choice (see students listed below). Research, especially where the students are actually involved in all aspects of it including data …

Both exercise and stress have an impact on learning and memory. Exercise appears to have positive effects on learning and memory while stress appears to have negative effects on learning and memory. Previous work in our lab has demonstrated that exercise enhances long-term potentiation mediated by electrical stimulus in the hippocampus and that stress decreases long-term potentiation mediated by electrical stimulus in the hippocampus. Long-term potentiation is a measure of the strengthening of the synapses following an electrical stimulus intended to model learning and memory. The hippocampus is the area of the brain commonly deemed responsible for long-term declarative memories.

The hippocampus is an area of the brain that mediates learning and memory by changing the properties of synapses between its neurons. This ability of synapses to change is known as synaptic plasticity. Long-term potentiation (LTP), a long-lasting increase in signal transmission between two neurons, is one of several phenomena underlying synaptic plasticity and is the cellular correlate of memory and learning. Several studies of LTP in mice show that there is a marked impairment of LTP in hippocampal slices taken from rodents exposed to stress. Their data suggests that stress may lead to deficits in learning and memory. In …

Both stress and exercise have significant physiological effects. Researchers have studied these effects throughout the body, and current evidence suggests that exercise and stress also have profound effects on the brain. While stress decreases brain function, exercise has been show to enhance brain function. Recently, researchers have begun to investigate the effects of stress and exercise on the brain simultaneously, instead of studying the effects individually. Our lab has furthered these studies through the use of electrophysiology and behavioral experiments. Four groups of mice were studied: a control group, a group that experienced a chronic stress protocol, a group that …
