[The escape reactions in cats during electrical stimulation of the hypothalamus leading to the occurrence of aggressive behavior].
The influence of brain electrical stimulation, which induced some elements of agonistic behavior, on the preference of an animal of one of two compartments of the experimental chamber was studied in 7 male cats with implanted hypothalamic electrodes. The animals avoided the compartment in which they were stimulated. Self-stimulation reaction could not be formed on the basis of the electrical brain stimulation inducing certain elements of agonistic behavior. Passage latencies were shorter when an animal left the less preferential compartment that in the case when in started from the more preferential one. The obtained evidence suggests that hypothalamic stimulation producing certain elements of agonistic behavior evokes in an animal a negative internal state.
