Abstract
IN each segmental ganglion of the leech, pairs of colossal cells (cell of Retzius) are found and bidirectional electrotonic type of transmission exists between these two neurones1,2. The amplitude of the spike is small, in the range of 20–30 mV. Because the resting potential of the cell is 30–50 mV, no obvious overshoot occurs. It is thought that no conduction of impulses occurs in the cell bodies of colossal cells1,2. This communication considers the effect of various ions on the electrical activity and electrical connexion between these cells.
