Abstract

A tactile stimulator was built for studying motion processing in the somatic sensory system of primates. This stimulator is used for assessing the responses of neurons of the somatic sensory system to stimuli moving in any traverse distance (range: 2-20 mm), with a variety of velocities (range: 4-120 mm/s), forces (range: 0-60 gf), and in any scanning direction. The stimulator is highly automated and can be used in combined psychophysical and neurophysiological studies in humans and in behaving monkeys.

摘要

为研究灵长类动物躯体感觉系统中的运动处理过程，构建了一种触觉刺激器。该刺激器用于评估躯体感觉系统神经元对在任何横向距离（范围：2 - 20毫米）内移动、具有多种速度（范围：4 - 120毫米/秒）、多种力（范围：0 - 60克力）且沿任何扫描方向移动的刺激的反应。该刺激器高度自动化，可用于人类和行为猴子的心理物理学与神经生理学联合研究。
