following the finding that rabbit schwann cells exhibit a large binding capacity for saxitoxin ( ritchie and rang , 1983 ) electrophysiological studies have shown that these cells not only express plasmalemmal voltage-gated sodium channels but also voltage-gated potassium channels ( chiu , shrager and ritchie , 1984 ; shrager , chiu and ritchie , 1985 ) .
