The Membrane Potential of the Anterior Byssus Retractor Muscle of Mytilus edulis

Naturevolume 187page1121 (1960) | Download Citation



As yet no reports of intracellular recording from the anterior byssus retractor muscle appear to have been made. The membrane potential can be measured with coventional glass micro-pipettes filled with 2.5 M potassium chloride, but satisfactory recordings have only been obtained with electrodes possessing tips of about 0.5µ or less in external diameter. Very few such electrodes are free from large tip potentials; but some satisfactory recordings have been obtained from the muscle in situ, using selected electrodes.
