Ephaptic influence of the electrical activity of muscle on the neighboring nerve.
Experiments were performed on isolated nerve-muscle and leg preparations of frog in order to investigate the excitatory influence of the electrical activity of muscle on the contiguous nerve under various conditions. The results show that the active muscles are able to induce multiple transmission of excitation from muscle to nerve and to modify the excitation travelling in the nerve being in contact with the muscle. It is concluded that under some special circumstances the ephaptic influence of the electrical activity of muscle on the nerve in its neighborhood can play an occasional role in the processes related with the nerve and muscle excitation.
