[Relation between the strength of stimulation of hypothalamic structures in the rabbit and behavior in the form of striking with the paws].
The behaviour in the form of tappings with forepaws after electric stimulation of 5 s duration was studied in rabbits with electrodes chronically implanted in the diencephalon. This species-specific behaviour is described following stimulations of threshold strength and gradually increasing to three thresholds. It has been found out that frontal, medial and posterior nuclei of the hypothalamus possess the greatest ability for eliciting such behaviour. During stimulation motor signs of avoidance behaviour dominate. The tappings are observed only in the post-stimulation period. Stimulation with two thresholds strength elicits the greatest number of tappings. There is a reliable relation between the number of tappings and total duration of the reaction. The possibility of reinforcing properties of the tappings based on emotional fear reaction to stimulation is discussed.
