1. The voltage responses to light of dark-adapted cockroach photoreceptors were recorded from the somata in the retina and the axons below the two basement membranes. 2. One or more spike-like fast depolarizations superimposed on the graded receptor potential were recorded in photoreceptor axons identified by Lucifer yellow injections. These spikes are voltage dependent in as much as they could be elicited with depolarizing current pulses as well as with light stimuli. In photoreceptor somata… CONTINUE READING
