A novel protocol to investigate motor training-induced plasticity and sensorimotor integration in the cerebellum and motor cortex.

abstract：:Motor cortex (M1) activity between postnatal weeks 5 and 7 is essential for normal development of the corticospinal tract (CST) and visually guided movements. Unilateral reversible inactivation of M1, by intracortical muscimol infusion, during this period permanently impairs development of the normal dorsoventral dist...
