Abstract

Touch is an active process, but how do the body's somatic sensors influence its movement? In this issue of Neuron, Nguyen and Kleinfeld show that afferent activity from the whiskers on a rat's face trigger rapid and prolonged excitation of the motor neurons that drive movements of the same whiskers. Positive feedback through this sensorimotor loop may serve to optimize the interaction between sensors and stimuli.

摘要

触觉是一个主动过程，但身体的躯体传感器如何影响其运动呢？在本期《神经元》杂志中，阮和克莱因费尔德表明，来自大鼠面部胡须的传入活动会触发驱动相同胡须运动的运动神经元的快速且持续的兴奋。通过这个感觉运动回路的正反馈可能有助于优化传感器与刺激之间的相互作用。
