To investigate the sensitivity to changes in excitability of motoneuron pool dependent on voluntary motor commands, we recorded motor evoked potentials (MEPs) and H-reflexes from the right flexor carpi radialis (FCR) muscle of normal human subjects. Amplitudes of MEPs were always larger than those of the H-reflex in both tonic and phasic muscle(More)
The effect of enflurane on somatosensory evoked potentials (SEP) was investigated in nine gynecological patients under nitrous oxide-enflurane anesthesia. SEPs were obtained from electrodes placed on the scalp C4 and earlobes by median nerve stimulation contralateral to the recording site. SEPs taken in a control study without enflurane consisted of six(More)
