<Bass HREF="file:///C|/JANET/05DOPA.HTM"> Running and Brain Dopamine Levels</B></H3> <P> The cardiovascular benefits of exercise have been well established and promoted in the general population. A new study in the <I> <B>Journal of Applied Physiology</B></I> reported what may be evidence that exercise provides a benefit to cognitive function as well. The authors found that daily spontaneous running significantly modulated the nigrostriatal dopaminergic system of rats, an area in the brain associated with the pathology of Parkinson's disease. The daily running rats had significantly enhanced sensorimotor and cognitive related behavioral responses over sedentary rats. Dopamine release rates were lower in the running rats, while potassium-stimulated release rates were similar to those of the sedentary rats.[1] <P> 1. Dluzen DE, Binjun L, Chen CY, DiCarlo SE.
