Cortical modulation of brainstem circuits is abnormal in cervical dystonia

Abstract

Objective: In healthy subjects, magnitude of hand-evoked blink reflex (BR) is increased if the stimulated hand is positioned in the peripersonal space. Here, we aimed to investigate the modulation of hand-evoked BR in peripersonal space to understand alterations of cortical modulations of subcortical structures in cervical dystonia.
