Abstract: The suction pipette technique was used to investigate the recovery of toad rod photoreceptors following small bleaches of 0.2‐3% of the rhodopsin. The reduction in sensitivity and the increase in noise elicited by bleaches were measured, and from these measurements the underlying rate of occurrence of photon‐like events was calculated as a function of time after the bleach. Exposure to hydroxylamine solution was used to hasten the decomposition of the meta‐rhodopsin photoproducts. The outer segment was exposed to 110 mm hydroxylamine in a...
