In the Cat with a penicillin motor focus, a transcortical reflex (RTC) can be triggered by stimulation of the muscle or the cutaneous branch of the radial nerve (DR - SR). We tried here to identify at a suprabulbar level, the proprioceptive pathway involved in triggering RTC. Cerebellar ablation did not modify the reflex. On the other hand reversibly inactivation of a rostral-dorso-medial part of VPL (VPLr) receiving short latency proprioceptive afferents, reversibly abolished the TRC elicited through DR stimulation, while SR stimulation was still effective. It is thus assumed that muscle and cutaneous afferents responsible for eliciting the RTC run in parallel pathways with distinct relay zones within the VPL nucleus.U
在具有青霉素运动中枢的猫中，通过刺激肌肉或桡神经皮支（DR - SR）可触发皮质下反射（RTC）。我们在此试图在延髓上水平识别参与触发RTC的本体感觉通路。小脑切除并未改变该反射。另一方面，接受短潜伏期本体感觉传入纤维的VPL（VPLr）嘴侧背内侧部分的可逆性失活，可逆性地消除了通过DR刺激引发的TRC，而SR刺激仍然有效。因此可以假定，负责引发RTC的肌肉和皮肤传入纤维在VPL核内具有不同中继区的平行通路中运行。
