Abstract

Behavior PaSadena, California California Institute of Biology, of Technology, THE DISCOVERY of behavior by Olds Milner (20), much work has been devoted to problems of localization of the neuroanatomical structure mediating this behavior. It is by now established that the anatomical region which is most closely associated with behavior is the medial forebrain bundle (23). This bundle in the rat (6, 7, 14, X7, 30) courses from the paleocortex through the lateral hypothalamus to the midbrain, in both directions. In contrast to the increasingly detailed information available regarding the loci of stimulation patterns of response for brain reward, little has been established about the neurophysio!ogical events in the medial forebrain bundle itself, or in other brain areas which underlie the phenomenon of . The present studies were carried out in search of the secondary further neurons activated when rewarding stimuli were applied to the medial forebrain bundle fibers. Preliminary studies utilizing anesthetized animals had failed to locate either evoked potentials or driven- responses evoked by stimulation of the critical areas.
