摘要

在电触觉(皮电)刺激下，记录了支配灵长类指垫的3条RA纤维的动作电位。负脉冲所需的电流是正脉冲的1.3-1.5倍。强度-持续时间常数约为151微米。与30 hz电触觉脉冲同步的超阈值正弦振动对电触觉夹带电流有轻微改变，表明可能存在电-机械转导相互作用。

The afferent neural response to electrotactile stimuli: preliminary results.

We recorded action potentials from three RA fibers innervating primate fingerpad, while applying electrotactile (electrocutaneous) stimulation. Negative pulses required 1.3-1.5 times more current than positive ones for entrainment. The strength-duration time constant was approximately 151 micros. Suprathreshold sinusoidal vibration synchronized to 30-Hz electrotactile pulses changed the electrotactile entrainment current slightly, indicating a possible electrical-mechanical transduction interaction.
