[Minute rhythms of haloperidol catalepsy in rats].
Haloperidol-induced (0.25-1.0 mg/kg) catalepsy in rats is characterized by rhythmic time fluctuations. Marked catalepsy was accompanied by slow regular waves at 2-4 and 5-7 min period. Natural or L-dopa-induced inhibition of the process involves the phase of irregular and frequent fluctuations. The study of time fluctuations of the muscular tone are believed important for predicting the development of drug-induced Parkinson's disease.
