title: [Effect of amizil and the ACTH4-10 fragment on the ability of mice to extrapolate the direction of movement].
abstract: Mice possessing the ability to extrapolate the direction of movement (100% of correct choices) were injected i.p. with different doses of m-cholinolytic amizil 2 hours before experiment. Doses of 2-5 mg/kg reduced the percentage of correct choices, the adequate solving strategy being replaced by stereotyped unidirectional reactions or stereotyped alternating responses. Doses of 8-12 mg/kg induced "refusals" to solve extrapolation problem. When amizil treated mice were intraventricularly injected with 1 mg/kg of ACTH4-10, their extrapolation ability was restored. This compensatory action of peptide could be mediated by its influence on cholinergic as well as on other neurotransmitter systems.
