title: [Effect of long-term hypokinesia on characteristics of phasic-tonic motor activity in monkeys].
abstract: Male rhesus-monkeys, 5-6 years old, were kept in recumbency for a long period of time during which they had to perform phasic-tonic motor tests. The monkeys showed significant changes in the tonic component of the motor act which led to a substantial deterioration of performance parameters on hypokinesia days 20 to 30. The process of recovery began immediately after exposure and on readaptation days 14-15 the tonic component of the motor act returned to normal. The motor skill which is a consecutive chain of phasic and tonic components can be viewed as an adequate model of a voluntary motor act. This may be used for measuring quantitatively functional changes of the motor apparatus and for studying the effect of different agents on primate motor functions.
