L = left, R = right, DL = dorsolateral, VL = ventrolateral, PFC = prefrontal cortex, CC = cingulate cortex, TC = temporal cortex, PMC = premotor cortex, MC = motor cortex, SMA = supplementary motor area, PPC = posterior parietal cortex, Ant = anterior, Post = posterior. Cluster sizes are reported in mm3. sc indicates that the peak is part of the same cluster as the peak listed immediately above in the table and that its size therefore is included in the preceding reported volume. Numbers in parentheses refer to architectonic areas. The same abbreviations are used in all tables (1–4).
P < 0.005 uncorrected. When no star is indicated P < 0.05 corrected for multiple comparision in single group analysis and P < 0.0001 uncorrected for inter-group analysis.
