[Increased food motivation in rabbits during prolonged automatic electric stimulation of lateral hypothalamic...

An automatic electric stimulation elicited a long-term focus in food motivation centers in rabbits, whose food-getting instrumental activity, EEG and some vegetosomatic parameters were studied. The focus induced the epileptiform EEG activity spreading from the hypothalamus up to the cerebral cortex. The food instrumental responses were either abruptly intensified or inhibited depending on the electrode localization. After cessation of the electric stimulation the focus remained without any sign of fading for one month.
