Within group activation maps for sentence completion task (a, b) and verbal encoding/retrieval task (c-e). For the Hayling sentence completion test, contrasts shown are (a) sentence completion versus rest and (b) the parametric contrast representing increasing activation with increasing difficulty. For the encoding/retrieval task, contrasts shown are (c) word classification versus experimental baseline, (d) correct recognition versus experimental baseline, and (e) correct rejection versus experimental baseline. For illustration purposes maps are thresholded at T = 4.5, 4, 6, 5, 5 respectively, extent threshold = 50 voxels. Left hemisphere shown on left of image.
