title: Brain acetylcholinesterase activity in Wistar and August rats with low and high motor activity (a cytochemical study).
abstract: Acetylcholinesterase activity was quantitatively evaluated by cytochemical method in brain structures (layers III and V of the sensorimotor cortex, caudate nucleus, nucleus accumbens, hippocampus CA3 field) of August and Wistar rats demonstrating high and low motor activity in the open field test. In August rats, acetylcholinesterase activity in the analyzed brain structures prevailed in animals with high motor activity in comparison with rats with low motor activity. In Wistar rats, the differences between the animals demonstrating high and low motor activity were less pronounced, but varied depending on the experimental series of studies. Comparisons of August rats with low motor activity and Wistar rats with high motor activity (maximum difference of motor function in these animals) revealed significant excess of acetylcholinesterase activity in layer III of the sensorimotor cortex in August rats and no differences in other brain structures of the examined animals.
