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 for movement disorder therapy in seven patients) was compared with scalp SEP in six age-matched Parkinsonian patients and six healthy younger subjects. Upon electric median nerve… CONTINUE READING
