Within the target area (VL) used for the stereotactic treatment of parkinsonian tremor and spasmodic torticollis, electrical stimulation as well as recording of somatosensory evoked potential (SEP) was performed. The effects of stimulation in the target area are facilitation of muscle tone showing some degree of somatotopic distribution. The recorded SEPs indicate a projection of an afferent system (probably of muscle afferents) to the target area. We assume that the target area is a relay station involved in the control of muscle tone. The interruption of muscle afferents in combination with the correct somatotopic localization of the lesion is important for the therapeutic efficacy in parkinsonian tremor and spasmodic torticollis.
在用于帕金森震颤和痉挛性斜颈立体定向治疗的目标区域（VL）内，进行了电刺激以及体感诱发电位（SEP）记录。目标区域内刺激的效果是促进肌张力，呈现出一定程度的躯体定位分布。记录的SEP表明存在一个传入系统（可能是肌肉传入）向目标区域的投射。我们推测目标区域是参与肌张力控制的一个中继站。肌肉传入的中断以及病变正确的躯体定位对于帕金森震颤和痉挛性斜颈的治疗效果很重要。
