NMDA receptor blockade reverses motor response alterations induced by levodopa.

abstract：:Human somatosensory evoked potentials (SEP) contain high-frequency (600 Hz) wavelet bursts possibly reflecting repetitive population spikes in thalamocortical axons and/or postsynaptic responses. To dissociate thalamic and cortical burst components the recovery of intrathalamic SEP (derived from electrodes implanted f...
