How Exercise Impacts The Brain And Cognition, Cody Larson Jan 2020

How Exercise Impacts The Brain And Cognition, Cody Larson

Biology and Microbiology Graduate Students Plan B Research Projects

Physical exercise has been shown to impact the brains composition and functionality. The changes that arise in the structure of brain, as result of engaging in physical exercise, give rise to cognitive changes. Structural changes are observed most notably in the prefrontal cortex and hippocampus. These changes are preceded by elevations in cerebral blood flow, and growth factors, resulting increased neuroplasticity and neurogenesis. Frequency, duration, intensity, and type of physical exercise can have differing effects on the brain. Moderate intensity aerobic exercise presents the most profound improvements in memory, and inhibitory control over time.
