The Talairach coordinates of the significant ALE clusters are presented for the conjunction of externally-paced and self-paced tapping (p < 0.01, FDR corrected) as well as for the contrasts of External > Self and Self > External (p < 0.05, uncorrected). The ALE values for the conjunction represent the minimum ALE value from either the externally-paced or self-paced ALE maps. The ALE values shown are the true values times 10‒3. The statistical contrasts between the two ALE maps are given as z-scores for External > Self and Self > External. BA, Brodmann area; IPL, inferior parietal lobule; M1, primary motor cortex; PMCd, dorsal part of the premotor cortex; PMCv, ventral part of the premotor cortex; S1, primary somatosensory cortex; SMA, supplementary motor area; SPL, superior parietal lobule; STG, superior temporal gyrus; VL, ventral lateral nucleus of the thalamus.
