C. R.末梢神经病变；触觉刺激对仓鼠前凸的增强作用。中国生物医学工程学报，26(6):867-871,1997。在雌性仓鼠中，研究了手触觉刺激引起的前凸中末梢神经的参与。在前前凸反应后，在5个不同的延迟时间进行手动腰骶触觉刺激，测量前凸潜伏期。术前资料收集后，分别行末梢神经病变（TNX）、对照前脑病变（FBX）和假手术（SH），术后再次对动物进行检测。分别比较术前和术后每次延迟时间对氯剂量的延迟。TNX组术后前凸潜伏期虽小但显著降低。SH组和FBX组的前凸潜伏期没有变化。这些结果表明末梢神经在生殖接触过程中介导感觉加工中起次要作用。
Wirsig-Wiechmann, C. R. Nervus terminalis lesions: Ii. Enhancement of lordosis induced by tactile stimulation in the hamster. Physiol Behav 61(6) 867–871, 1997.—The involvement of the nervus terminalis in lordosis, induced by manual tactile stimulation, was investigated in the female hamster. Lordosis latencies were measured in response to manual lumbosacral tactile stimulation, which was performed at 5 different delay times after the previous lordotic response. Nervus terminalis lesion (TNX), control forebrain lesion (FBX), and sham (SH) surgeries were performed after preoperative data was collected, and animals were tested again postoperatively. Latencies to lordose were compared separately for each delay time between preoperative and postoperative tests. The TNX group showed small, but significant, decreases in lordosis latencies postoperatively. Lordosis latencies for the SH and FBX groups did not change. These results suggest that the nervus terminalis plays a minor role in mediating sensory processing during reproductive encounters.
