AEON: BOLD main effect. 3D whole-brain renderings of the main effects (0th order) in action execution (AEN), action observation (AON) and action execution–observation (AEON) networks. Note, in the AEON, the considerable overlap of effects in both the cerebral cortex and the cerebellum. Different thresholds were used for the 3 maps: P_u < 0.0001 (k ≥ 10; P_u = P uncorrected for multiple comparisons) was used for the AE condition; P_u < 0.05 (k ≥ 10; P_u = P uncorrected for multiple comparisons) was used for the AO condition; and P < 0.05 (k ≥ 10), with a small volume correction applied to the AO map, was used to obtain the AEON.
