The silent period after contralateral and ipsilateral transcranial magnetic brain stimulation was studied in patients with Parkinson's disease before and after dopaminergic and anticholinergic(More)
Electrical stimulation over muscle tendons produces a transient suppression of voluntary EMG activity; its onset latency is approximately 55 ms in the forearm extensor muscles. This phenomenon has(More)
We studied the effects of hyperventilation under control of the end-tidal PCO2, on the electromyographic silent period evoked by transcranial magnetic brain stimulation and by peripheral nerve(More)
In active muscle, a supramaximal conditioning stimulus to peripheral nerve produces a classic silent period in the EMG. The present experiments examined the effect of this type of conditioning(More)
