图1.不同时间记录的单个下橄榄核神经元的逆行动作电位。每个记录是5个叠加扫描。注意，在A中，AB延迟并在2次试验中反应完全失败；在B中，比A略强的刺激总是能引起反应，但B成分在2次试验中失败。另一个橄榄单位的逆行动作电位对4个刺激的反应速度为260次/秒。请注意，第三个应答的B分量在所有试验中都失败了，在4个试验中有3个试验的第四个应答失败。D和E，在两个单独的低阈值刺激的单个橄榄单位的逆行动作电位(见正文)。F和G是单个橄榄核单位对小脑表面两个位点刺激的反应；F是在一个低阈值G处，在另一个只能诱发顺向棘波的点。H，上：逆向场电位的示踪；下：直方图，显示32个不同的低阈值(或最佳点--BPS)刺激后，逆向场电位潜伏期的分布。时间刻度指的是H的顶部和底部。高于C的时间校准适用于C，高于A的时间校准适用于所有其他记录。A旁边的电压校准适用于A、B、C、F和G，D旁边的电压校准适用于D和E；负值为上行。
Fig. 1. A and B, Antidromic action potentials of a single inferior olivary neurone recorded at different times. Each record is 5 superimposed sweeps. Note, in A, AB delay and complete failure of the response in 2 trials; in B, a slightly stronger stimulus than in A always evokes a response, but the B component has failed in 2 trials. C, Antidromic action potentials of another olivary unit in response to 4 stimuli at 260/sec. Note that B component of third response has failed in all trials and of fourth response in 3 out of 4 trials. D and E, Antidromic action potentials of a single olivary unit stimulated at two separate low threshold points (see text). F and G, Responses of a single olivary unit to stimulation at two loci on the cerebellar surface; F, at a low threshold point, G, at another point from which only orthodromic spikes could be elicited. H, Top: tracing of antidromic field potential; Bottom: histogram showing distribution of latencies of antidromic action potentials following stimulation of 32 different low threshold points (or'best points'--BPs). Time scale refers to both top and bottom portion of H. Time calibration above C applies to C, that above A to all other records. Voltage calibration beside A applies to A, B, C, F and G, that beside D to D and E; negativity is upwards.
