Electrophysiologic recordings in a patient with a discrete unilateral thalamic infarction.
The electroencephalogram, and somatosensory and auditory evoked potentials were recorded from a patient, who, at necropsy, showed a restricted unilateral thalmic infarct involving predominantly the anterior and lateral thalamus. The electroencephalogram showed distinct monomorphic delta activity and a suppression of the alpha rhythm over the side of the lesion. Short latency somatosensory evoked potentials were present bilaterally; mid-latency somatosensory evoked potentials were absent ipsilateral to the lesion. Both mid-latency and long latency auditory evoked potentials were normal.
