Active brain regions.

Active regions are significant at Z>2.7, except for the activity in the medial orbitofrontal cortex which was not significant (n/s) at this threshold. All reported brain coordinates are in the standard space of MNI (Montreal Neurological Institute).
List of active brain regions (from the integrated z-map in figure 1) in an implicit task attending a change in colour of a fixation during which infant and adult faces were presented for 300 ms but, crucially, did not help complete the task. As expected, both infant and adult faces elicited significant activity mainly in striate cortices and along ventral and dorsal pathways. Importantly, however, there was significant activity in the medial orbitofrontal cortex only to the infant faces but not to the adult faces.
