In rats raised from birth under a regular dark-light cycle, retinal dopamine (DA) levels were low at 12 days, increased progressively and steeply at 16, 20, 30 and 60 days and peaked at about 75 days postnatally. Dark-rearing from birth suppressed the magnitude of the normal developmental pattern of DA concentrations in retina and at 20, 30 and 60 days of age they were markedly smaller compared with those in age-matched controls grown under regular cyclic illumination. In adult rats reared up… CONTINUE READING
