In this report BOLD fMRI to investigate the functional deficits of subjects with long-term occupational solvent exposure. Subjects underwent fMRI while performing a Sternberg task and N-back working memory task. We used an exploratory voxel-wise and an ROI analysis to test the hypothesis that the occupationally exposed subjects show hypo-activation in regions associated with working memory when compared to a carefully matched control group. the results suggest that prolonged occupational solvent exposure is related to a decreased activation in regions associated with working memory.
