A two stage experiment concerned with the neurochemical effects of visual deprivation was conducted. In Stage I rats were enucleated at 15 days of age and sacrificed at either 30, 50, 75, or 100 days. Stage 2 research involved removing the eyes at 100 days and sacrificing at 115, 135, 160, or 185 days of age. A littermate normal was housed with each enucleate. No differences were present in the visual cortex in Stage 1 but the control animals had greater protein values and RNADNA and proteinDNA ratios in Stage 2. Several other significant results occurred and are discussed. The period of greatest cellular activity was at 50 days or 75 days in all tissues. Author
