t test reflects the statistical difference between the two conditions, as computed by SPM99. Regions accompanied by an asterisk also demonstrated a significant Dm effect for impression formation trials (i.e., impression-hits > impression-misses). The coordinates refer to the Montreal Neurological Institute stereotaxic space.
