Properties of utricular and saccular nerve-activated vestibulocerebellar neurons in cats.

abstract：:Parkinson's disease (PD) adversely affects information processing and motor performance. The impact of aerobic exercise on modifying the deleterious effects of PD underlying information and motor control processes is not well established. The primary aim of this project was to determine the effects of an 8-week high i...
