Abstract
ELECTRICAL excitability is more complex in cell bodies than in axons. In various nerve cells there is a voltage-sensitive permeability to calcium as well as to sodium and potassium. Furthermore, increased calcium in the cytoplasm of nerve cell bodies increases their potassium permeability. In voltage-clamped Helix neurones, Meech and Standen1,2 reported that a substantial fraction of the potassium conductance activated during a depolarisation depends on an inward calcium current.
