A procedure for chronic recording of diaphragmatic electromyographic activity.
A simple procedure for recording of diaphragmatic electromyographic activity in awake, freely behaving animals is described. This procedure produces highly stable recording of muscle activity for very long periods. Because of its ease of use, the procedure has become the technique of choice for acute recording in our laboratories as well. The present procedure can also be adapted for chronic recording of electromyographic activities from nonrespiratory muscles. This option thus offers a variety of applications to those involved in investigations into the central neuromotor control of movement, pattern generation and autonomic functions.
