Abstract

Single unit recordings from dorsal column neurons were made during application of mechanical somatic stimuli moving at controlled velocities across the neuron's receptive field. The neurons responded in stereotypic patterns which changed with altered stimulus parameters of velocity, direction and intensity. Spatial analysis of the response patterns indicates that the neurons generate action potentials when the stimulus probe activated particular discrete locations within the receptive field.

摘要

在对背柱神经元施加以可控速度在神经元感受野上移动的躯体机械刺激期间,进行了单细胞记录。神经元以刻板模式做出反应,这种模式会随着速度、方向和强度等刺激参数的改变而变化。对反应模式的空间分析表明,当刺激探针激活感受野内特定离散位置时,神经元会产生动作电位。
