Environmental light and heredity are associated with adaptive changes in retinal DHA levels that affect retinal function.
Retinas of rats and mice react to environmental and genetic stimuli by altering the level of DHA in their rod outer segment membranes. We propose that this adaptation is a neuroprotective response to control the number of photons captured by rhodopsin and the efficiency of visual transduction, under conditions where excessive activation of the transduction cascade could lead to cell death.
