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 …
