Effects of arrested cerebellar development on locomotion in the rat. Cinematographic and electromyographic analysis.

abstract：:For an understanding of how various degrees of altered use (training, disuse) affect the properties of skeletal muscles, it is important to know how much they are used normally. The main aim of the present project was to produce such background knowledge for hindlimb muscles of the cat. In four adult female cats, each...
