Abstract
Three patients with well-defined clinical and radiographic lesions were studied with somatosensory evoked potentials (SSEP). The primary scalp potentials from stimulation of both the arm and leg (.hivin.N20 and .hivin.P40) can be lost with thalamic lesions and would be consistent with these potentials being generated in either the thalamus or thalamocortical radiations.Keywords
