Neurochemical Changes in Specific Regions of Rat Brain During Different Phases of Conditioning,
Abstract
The activity changes of RNA polymerase, choline acetyl transferase, acetylcholinesterase and monoamine oxidase in five brain areas were investigated in groups of water deprived rats trained to run for water reward, extinguished after training or retrained after extinction. Marked increases in RNA polymerase and choline acetyl transferase activities were observed in the hippocampus of the experimental animals. A pronounced increase in the activity of RNA polymerase was also found in the posterior hypothalamus of trained rats. No significant changes in the activities of the other enzymes tested were observed as a result of training. (Author)
