Abstract
MICROELECTRODE studies of inner smooth muscle cells of unstimulated rabbit carotid arteries show a stable membrane potential1,2, as do sucrose-gap records from sheep carotid arteries3,4, the latter method records only from cells that are widely interconnected electrically. Information about the electrical behaviour of the outer muscle of arteries is particularly important as only the outer muscle is innervated, and it is much less sensitive than inner muscle to vasoconstrictor agents5.
