Abstract

It has been shown that Ca2+ plays important roles in controlling sensitivity of invertebrate photoreceptors. Lisman and Brown (1972) showed that during intracellular ionto-phoretic injection of Ca2+ into Limulus ventral photoreceptors, there was a progressive diminution of the light response. They postulated that light stimulation leads to an increase in intracellular Ca2+which in turn reduces responsiveness to light stimulation. Direct measurement of intracellular Ca2+ concentration in Limulus ventral photoreceptors and Balanus photoreceptors indicates that illumination does induce an increase in the intracellular Ca2+ concentration (Brown and Blinks 1974). Hanani and Hillman (1976) showed that the barnacle photoreceptor sensitivity either decreased or increased after exposure to illumination, and both phenomena were influenced by external Ca2+ concentration. In a study on the retina of the honey bee drone. Bader et al. (1976) showed that an increase in intracellular Ca2+ concentration played a central role in light adaptation.
