Voltage-sensitive conductances increase the sensitivity of rod photoresponses following pigment bleaching.


KEY POINTS Following substantial bleaching of the visual pigment, the desensitization of the rod photovoltage is not as substantial as the desensitization of the rod outer segment photocurrent. The block of cation conductances during the internal dialysis of Cs+ further desensitizes the photovoltage thereby eliminating its difference in desensitization with… (More)
