Multiple light-evoked conductance changes in the photoreceptors of Hermissenda crassicornis.

Abstract

1. Light responses were recorded from the photoreceptors of Hermissenda crassicornis. The response to a flash is a complex potential change involving an initial depolarization, a hyperpolarization, and a depolarizing tail. None of the phases of the response are due to synaptic interactions.2. Polarization of the membrane by extrinsic current indicates that… (More)
