“…Several groups of researchers (e.g., Livingston & Escobar, 1971;Persinger & Makarec, 1987; Roberts, Varney, Hulbert, Paulsen, Richardson, Springer, Smith-Shepard, Swan, Legrand, Harvey, & Strichen, 1990), using different methods and perspectives, have suggested that the behaviors and experiences of patients who display or who are inferred to display electrical lesions within the hippocampal-amygdaloid regions are extreme examples of the normal population. Roberts and associates (Roberts, Paulsen, Marchman, & Varney, 1988; Roberts, Varney, Hulbert, et al, 1990; Roberts, Varney, Paulsen, & Richardson, 1990) have shown repeatedly that patients who exhibit quantitative increases in complex partial epileptic-like signs also display dichotic listening deficits and multiple elevations on the MMPI. Both the dichotic listening and MMPI scores improve (Springer, Garvey, Varney, & Roberts, 1991) after treatment with the anticonvulsant carbamazepine (Tegretol).…”
