Experimental model of psychic stress.
An experimental model for the induction of an informational psychic stress in the rat, comparable with the psychic stress in man, is described. The method consists in the production of the emission of significant acoustic signals by an "emitting" group of animals, subjected in an aleatory manner to electroshocks. The acoustic nociceptive signals are heard by a "receiving" group of animals. In this "receiving" group are studied the behaviour and the neuroendocrine changes. This experimental model may be useful for studies of psychopharmacology, for the research of psychotropic drugs and for the determination of their action upon the harmful effect of informational aggressions and psychic stress.
