摘要
The cutaneous silent period (CSP) refers to the brief interruption in voluntary contraction that follows strong electrical stimulation of a cutaneous nerve. The CSP is a protective reflex that is mediated by spinal inhibitory circuits and is reinforced in part by parallel modulation of the motor cortex. This review summarizes current understanding of the afferents and circuits that are responsible for producing CSPs; the utility of the CSP for investigating peripheral and central nervous system disorders; and the relationship between the CSP, other cutaneous reflexes, and peripheral silent periods.
