[Pinch-induced catalepsy in rats of various genetic groups with different predisposition to audiogenic epilepsy]. 2010

Proportion of animals which developed pinch-induced catalepsy and the duration of this state were analyzed in rats of several genotypes which differed in audiogenic epilepsy proneness and compared with "audiogenic" catalepsy after a sound-induced seizure fit. The following genotypes were studied: Wistar, KM (Krushinsky-Molodkina) strain and substrains "4" and "0" (selected from KM and Wistar hybrid population for high "4" and low "0" audiogenic epilepsy proneness). Adult KM and substrain "4" rats developed the most intense pinch induced catalepsy, whereas Wistar and 2-month-old KM showed practically no catalepsy. After a single sound exposure pinch-induced catalepsy developed in all animals which demonstrated an audiogenic seizure fit--in KM, substrain "4", part of Wistar rats and several animals of substrain "0", latency of the fit onset in all rats being shorter than initially. After sound exposure pinch-induced catalepsy was revealed even in those substrain "0" rats, which demonstrated no audiogenic fits. It is suggested that despite the phenomenological similarity between cataleptic states of different origin (pinch-induced, "audiogenic") their neurophysiologic substrates overlap only partially. The findings are considered as presenting genetic model for further analysis of catalepsy.

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.

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.

D020195 Epilepsy, Reflex A subtype of epilepsy characterized by seizures that are consistently provoked by a certain specific stimulus. Auditory, visual, and somatosensory stimuli as well as the acts of writing, reading, eating, and decision making are examples of events or activities that may induce seizure activity in affected individuals.
