Abstract

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

摘要

对三名具有明确临床和影像学病变的患者进行了体感诱发电位（SSEPs）研究。数据表明，刺激手臂和腿部所产生的头皮初级电位（N20和P40）可因丘脑病变而消失，这与这些电位在丘脑或丘脑皮质放射中产生的情况相符。
