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.
