abstract：:Rats kept in the dark (i.e., less than 0.1 lux) from birth until 15 days were exposed to light. In vivo incorporation of 14C-leucine into acid insoluble material and in vitro aminoacylation of tRNAleu were studied in visual, somaesthetic and motor brain cortices. A significant increase of both 14C-leucine incorporatio...
