Here we review murine evidence about the effects of exercise on discrete brain regions involved in important CNS functions. Exercise is brain food: the effects of physical activity on cognitive function. Physical exercise has been shown to positively modulate brain functions by increasing neural activity and/or by activating additional brain areas (e.g., neural plasticity, neural compensation), thereby counteracting degenerative processes and improving motor and/or cognitive functions in young and older adults alike. When you exercise, you help circulate blood throughout your body.
