The amount of visual information an animal can extract from its environment is ultimately limited by the signaling performance of its photoreceptors. To maximize their performance photoreceptors must be able to accommodate large changes in input caused by the dynamic properties of the visual environment and the animal's own behavior. This is likely to require a range of adaptation mechanisms operating over multiple time scales. Using intracellular recordings, we investigated the effects of developmental light rearing conditions, and the effects of two-hour light or dark exposure prior the experiment, on the signaling performance of adult Drosophila melanogaster photoreceptors. We show that light-rearing amplifies photoreceptors' voltage responses to light contrast changes by at least 20% and accelerates them by 3 ms. We argue that these differences mostly reflect changes in the timing of the early phototransduction reactions, some of which are persistent. However, being born and nurtured in certain lighting conditions does not set an ultimate limit for the signaling performance of Drosophila photoreceptors. Two-hour light exposure prior to the experiment can improve the information capacity of dark-reared photoreceptors close to the values of light-reared photoreceptors by reducing voltage noise. This effect may originate from plastic changes in the utilization of phototransduction proteins and ion channels.
