Positively loaded voxels were primarily associated with tasks involving lexical–semantic processing, naturally including many comprehension tasks. Negatively loaded voxels were associated with tasks involving phonological–motor processing, including many production tasks. We give the percentage of positive and negative voxels for the regions of interest constituting the dorsal and ventral streams and the mean of positive and (separately) negative voxels. For each stream, the table lists 15 regions of interest with the highest percentages of positive (ventral stream) and negative (dorsal stream) voxels.
