Abstract: In a series of experiments, electrical stimulation of the ventral fornix columns in rats was found to be highly rewarding although response rates were not as high as in medial forebrain bundle-lateral hypothalamic (MFB-LH) self-stimulation. Septal lesions selectively reduced fornix but not MFB-LH self-stimulation behavior. Responding for fornix stimulation was unaffected by cortical and MFB-LH lesions. The results established the reinforcing properties of fornix stimulation and point to the presence of a major reward pathway independent of MFB influences.
