Abstract
The photoreceptors of the giant barnacle are distinguished anatomically by large axons, visible under the dissecting microscope even to their presynaptic terminal arborizations. Intracellular recordings made from these cells near their presynaptic arbor have shown that the ocellar response to light is conducted with little decrement to the presynaptic terminals, and have demonstrated the presence of voltage-sensitive calcium channels in this region of the cell (Hudspeth & Stuart, 1977; Ross & Stuart, 1978; Edgington & Stuart 1979,1981). Using optical methods, Ross and colleagues have studied the time course of the resulting changes in intracellular calcium concentration (Stockbridge & Ross, 1984).
