Effects of Early Weaning on Some Free Amino Acids and Acetylcholinesterase Activity of Rat Brain

The effects of environmental conditions upon the brain composition of young animals have become increasingly evident. The first papers in this field were those of Levine et al. [8] and of Bennett et al. [2]. These two groups studied the effects of handling upon phospholipid accumulation and level of acetylcholinesterase activity, respectively. No studies have been made, to the best of our knowledge, on amino-acid changes in brain due to environmental manipulations.
