Abstract

To appraise the extent of light responsivity of the retinal dopaminergic system in the early postnatal period, dopamine content (DA) of retinas of cycling-light-reared and dark-reared guinea pigs was determined. DA storage postnatally was suppressed in dark-reared animals. Their retinas responded to a brief light stimulus by rapidly increasing DOPA synthesis and DA utilization, but not to the extent of the response of cycling-light-reared animals. Dopaminergic retinal neurones depend on light stimulus for the complete development of some of their neurochemical characteristics.
