从腹侧尾侧核记录正中神经刺激的体感诱发电位（SEP）。它们包括单相或双相电位，平均起始潜伏期为13.8 ms。更复杂的SEP正中神经刺激从皮层获得。SEP由两个主要的正波，P1和P2，并记录在中央前回和中央后回，表明体感信息会聚到运动皮层，可能是用于整合关键的运动活动。2例患者面部运动的运动表征大于相应的感觉表征。这种更大的面部运动表征，更具体地说，是嘴唇和舌头的运动表征，可能与人类获得模仿和语言表达有关。
Somatosensory evoked potentials (SEP) to median nerve stimulation were recorded from the nucleus ventralis caudalis. They consisted of monophasic or diphasic potentials with mean onset latency of 13.8 ms. More complex SEP to median nerve stimulation were obtained from the cortex. The SEP consisted of 2 major positive waves, P1 and P2, and were recorded over both the precentral and postcentral gyri, suggesting that somatosensory information convergest to the motor cortex, probably to be used for the integration of critical motor activity. In 2 patients, the motor representation of facial movements was larger than the correspondent sensory representation on the postcentral gyrus. This larger motor representation of the face and more specifically of the lips and tongue may be related to human acquisition of mimicry and articulation of language.
