Olds¹ showed that stimulation of many areas of the brain could be used as a "reward" to maintain bar pressing and other behavior. The neurological basis for the "rewarding" effects elicited from these areas remains unknown. Several bits of evidence summarized elsewhere² suggest a link between self-stimulation phenomena and specific activity of the rhinencephalon. If such localized specific activity were essential for self-stimulation it should be possible to abolish self-stimulation effects from a remote electrode by surgical removal of the crucial parts of the rhinencephalon. In a previous study² the septal areas and the continuity of the fornix columns were found not to be essential for maintained basal tegmental self-stimulation. Another area which has been thought to be closely involved with motivational systems and self-stimulation is the amygdala. Schreiner and Kling³ produced marked changes in eating habits, sexual behavior, and general activity by producing lesions in . . . [Full Text PDF of this Article]
