title: Are emotion and motivation localized in the limbic system and nucleus accumbens?
abstract: Groups of control rats without surgery or groups of rats prepared with surgical lesions of the septal nuclei, amygdala, cingulate cortex, accumbens nucleus, section of the fornix, or sham surgical operations, were tested in a simple autonomic conditioning situation (conditioned defecation). Control rats and rats with lesions of the accumbens nucleus were also tested in a straight alley maze under varying conditions of water deprivation. In general, the lesions had little effect except that amygdaloid damage impaired acquisition of conditioned defecation. The theory that 'emotion' and 'motivation' can be localized in the 'limbic system' and nucleus accumbens is discussed critically.
