Origin of the low-level EMG during the silent period following transcranial magnetic stimulation.

Abstract

OBJECTIVE The cortical silent period refers to a period of near silence in the electromyogram (EMG) after transcranial magnetic stimulation (TMS) of the motor cortex during contraction. However, low-level EMG of unknown origin is often present. We hypothesised that it arises through spinal reflexes. Sudden lengthening of the muscle as force drops during the… (More)
