Abstract
We studied the effects of hyperventilation under control of the end-ti dal PCO2, on the electromyographic silent period evoked by transcrania l magnetic brain stimulation and by peripheral nerve stimulation. We a lso studied the effects of hyperventilation on the threshold, latency and amplitude of motor potentials. Hyperventilation significantly redu ced the duration of the cortical silent period, but did not affect the length of the peripheral silent period. Neither did it alter the late ncy, amplitude or threshold of the motor potentials. These findings su ggest that hyperventilation selectively depresses motor cortical inhib ition in humans.
