This BSL PRO Lesson explains how to isolate the gastrocnemius muscle of the frog and its somatic motor nerve (the sciatic nerve) and describes the hardware and software setup necessary to record threshold voltage and contractile responses.
* These objectives are covered in the introductory text and recording template for BSL 4.0.1 or above only.
Isolate the gastrocnemius muscle and stimulate to observe and measure threshold and maximal response, and summation, tetanus, and fatigue.
