In Vivo Measurement of the Compound Muscle Action Potential in a Rat

Source: Wild, B. M., et al. In Vivo Electrophysiological Measurement of the Rat Ulnar Nerve with Axonal Excitability Testing. J. Vis. Exp. (2018) This video demonstrates the procedure for recording compound muscle action potential (CMAP) in rats by applying electrical stimuli to the ulnar nerve, adjusting electrodes for optimal signal, and increasing stimulation to assess nerve functionality. This method enables the in vivo investigation of the peripheral nerve functions in neurological disorders.
