Alcohol researchers are interested in other functions of the limbic system as well. Damage to certain parts of the limbic system leads to abnormalities in emotional functioning, the sense of smell (i.e., olfaction), and the ability to use one sense (e.g., vision) to learn something in another sense (e.g., touch) (i.e., cross-modal functioning). In all these categories of function, researchers have observed deficits in alcoholics (Evert and Oscar-Berman 1995). Moreover, alcoholics with KS appear to have greater impairment in some of these functional areas than do non-KS alcoholics.
