"I am involved with Research because I enjoy learning through practice. You can widen your knowledge from the literature that you read and the classes that you attend, but when you formulate your own project and see the information that you are creating for others, there is much more of a thrill."

Research Description

Effects of Aerobic Exercise on Critical Regions of the Prefrontal Cortex in Older Adults
Compared to other analysis techniques for various brain regions, the amount of research regarding voxel-based morphometry (VBM) on areas in the prefrontal cortex is scarce. Assessment of the VBM changes of the Orbitofrontal Cortex and Dorsolateral Prefrontal Cortex will provide insight on the effects that aerobic exercise has on these regions. A group of elderly adults (age 65 and older) will undergo walking exercises to establish an appropriate energy expenditure and MRI scans will be taken pre- and post-workout. It is predicted that as participants engage in aerobic exercise there will be a significant change in the VBM with an increase in gray matter volume to the orbitofrontal cortex and dorsal lateral prefrontal cortex.
