Conjunction analysis was conducted at the first level on each event of interest in the speaking tasks and writing tasks using subjects' individual SPMs of the minimum t statistic over the contrasts specified in each task (speaking: Spic>Ssyl; writing: Wpic>Wchr). The results were thresholded at voxel-level p < 0.001 with cluster-level FWE corrected p < 0.05. Spic: speaking picture naming, Ssyl: speaking syllable repeating, Wpic: written picture naming, Wchr: normal word copying, BA: Broadman's area.
