Abstract
Synaptic responses of neurons at the low thoracic level to microstimulation of a stepping strip in the dorsolateral funiculus with frequency of 20 and 40 pps were recorded in mesencephalic cats. Histograms of latencies of single neurons were usually monomodal, whereas two modes at 2-3 ms and 5-7 ms occurred in composed histograms. The data obtained show that decremental reverberation exists under these experimental conditions.
摘要
在中脑猫中记录了胸段低位水平神经元对背外侧索中步带以20次/秒和40次/秒频率进行微刺激的突触反应。单个神经元潜伏期的直方图通常是单峰的，而在合成直方图中出现了2 - 3毫秒和5 - 7毫秒的两个峰。所获得的数据表明在这些实验条件下存在递减性折返。
