Abstract

The purpose of this technical note is to present the design of an eight-channel telemetry system of dimensions and weight small enough to record muscular forces and EMGs simultaneously from gastrocnemius, soleus, plantaris and tibialis anterior muscles of a freely moving cat. All schematics for constructing the telemetry device are shown in detail. Using this system, we were successful in measuring force and EMG data of all four instrumented muscles in freely moving animals. The telemetry system presented here has the advantage over a conventional cable system that recordings may be obtained at any time in the freely moving animal without interference by an experimenter.

摘要

本技术说明的目的是介绍一种八通道遥测系统的设计，该系统的尺寸和重量足够小，能够同时记录自由活动猫的腓肠肌、比目鱼肌、跖肌和胫骨前肌的肌肉力量和肌电图。文中详细展示了构建该遥测设备的所有原理图。使用该系统，我们成功地测量了自由活动动物体内所有四块被测肌肉的力量和肌电图数据。此处介绍的遥测系统相对于传统的有线系统具有优势，即可以在自由活动的动物身上随时获取记录，而不受实验者的干扰。
