[Catatonia as an element of submissive behavior in mice during interspecies agonistic interactions]

A catatonia-like state was elicited in male mice with different experience of social interactions, by pinch of scruff of the neck in a suspended state. In submissive males with long experience of defeat the total time of catatonia reaction during test is considerably greater than in aggressive individuals with a long experience of victories. The change of the social status of the individuals resulting from agonistic interactions leads to a change of the catatonia reaction: manifestation of submissive behaviour is accompanied by an increase of total time of catatonia reaction in the test, the aggressive behaviour is accompanied by its decrease.
