摘要
Abstract
To address the challenges of prolonged reward training and uncontrollable speed in activating forward movement during rat locomotion regulation,an optimized forward motion activation method of rats based on the traditional method and a speed-controllable regulation approach were proposed.The medial forebrain bundle(MFB)stimulation strategies were improved by investigating the regulatory mechanism of MFB electrical stimulation on rat forward locomotion.At the same time,speed-controllable modulation was achieved through adjustments in stimulation amplitude and frequency.It is found that the forward movement can be successfully activated without reward training using the optimized MFB electrical stimulation strategy,achieving a successful rate of movement execution exceeding 95%and the fastest controllable speed of 24.52 m/min.Compared with existing studies,this approach reduced the modeling time of speed-controllable rats markedly and realized precise regulation of rat forward movement utilizing lower stimulation parameters.关键词
