Predispositions to pendulum movements (PMs) and catalepsy was studied in rat strains selected for predisposition to catalepsy and for enhanced or suppressed PMs. Positive correlation between PMs and catalepsy at earlier stages of selection changed to negative at later stages. Based on these data, it was hypothesized that the genes that determine the predisposition to catalepsy affect the expression of the gene determining PMs in such a way that different PM alleles become dominant in the cases of moderate and strong effects of the catalepsy genes.

UI MeSH Term Description Entries
D002375 Catalepsy A condition characterized by inactivity, decreased responsiveness to stimuli, and a tendency to maintain an immobile posture. The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D019956 Stereotypic Movement Disorder Motor behavior that is repetitive, often seemingly driven, and nonfunctional. This behavior markedly interferes with normal activities or results in severe bodily self-injury. The behavior is not due to the direct physiological effects of a substance or a general medical condition.
