[The influence of damage to the septum pellucidum on the effects of electrical stimulation of the hypothalamus in rabbits].
In chronic experiments the influences of septal lesions on the behavioural emotional effects of electrical stimulation of various hypothalamic nuclei were investigated. The total ablation of the septum caused irreversible increase of the lateral hypothalamus self-stimulation and reversal of the negative emotional responses (escape--avoidance) to the medial hypothalamus stimulation into the positive self-stimulation behaviour. When the septal ablation was only partial, involving mainly the medial nucleus, effects were weaker and lasted only 2-3 days after the surgery. The role of the septum in the septohippocampal behavioural inhibition system (J. Gray) is discussed.
