This abstract aims to help address multiple comparison issues in functional MRI experiments. It does this through the utilization of directly registered tissue segmentation maps obtained through a multiple-echo, echo planar imaging (EPI) acquisition. The tissue maps are used to mask out the gray mater, which reduces the amount of voxels being analyzed, and provide a functional map with fewer false positives and negatives.
