In the marine mollusc, Hermissenda crassicornis, Type B photoreceptors exhibit an IPSP to both presynaptic hair cell stimulation and microapplication of gamma-aminobutyric acid (GABA) to the terminal branches. It was found that both the endogenous IPSP and the response to exogenously applied GABA were mediated to a large part by an outward current which reversed at approximately -80 mV. Additionally, these hyperpolarizing responses were found to mask a smaller depolarization that was mediated… CONTINUE READING
