Sex differences in semantic language processing: a functional MRI study.

Predictions based on two models of sex differences in cerebral organization of language were compared by examining fMRI patterns of 10 females and 9 males during a semantic processing task. Both groups displayed activation of left inferior frontal gyrus (IFG), left superior temporal gyrus (STG), and cingulate. Females, but not males, showed bilateral IFG and STG activation. Further analyses revealed females had less diffuse left activation and greater right posterior temporal and insula region activation than males. Results support both an interhemispheric and an intrahemispheric model of sex differences in language, suggesting that the models may not be mutually exclusive.

The neuropsychology of multiple sclerosis: contributions of neuroimaging research.

Multiple sclerosis (MS) is often associated with cognitive and emotional changes that affect daily activities and quality of life. Deficits in memory, executive function, processing speed, and other cognitive domains are frequently reported. In addition, mood disturbances and fatigue are common. In this article, the authors highlight research on individual differences in the neuropsychology of MS, and emphasize neuroimaging studies that help elucidate the basis of the deficits.

Interhemispheric transfer in multiple sclerosis.

Interhemispheric transfer (IHT) was investigated in patients with multiple sclerosis (n = 20) and healthy control subjects (n = 23). On verbal dichotic listening and tachistoscopic reading tests, MS patients showed a pattern of left-sided suppression and/or right-sided enhancement, consistent with impairment of IHT. Patients with chronic-progressive MS were most affected. Clinical and empirical implications are noted.
