title: Gamma aminobutyric acid effect on acetylcholine level and metabolism in rat cerebral cortex.
abstract: Gamma aminobutyric acid injected into the lateral brain ventricle of white rats in doses of 0.6, 0.8 and 1.6 mg raised the level of acetylcholine and in doses of 0.2, 0.4, 0.6, 0.8 and 1.6 mg increased acetylcholine synthesis. The effects were greatest 15 minutes after injection. Gamma aminobutyric acid injected intraventricularly in doses of 0.6 mg increased the activity of choline acetyltransferase but had no effect on the activity of choline esterase.
