Coordinates are in millimeters according to Talairach and Tournoux (1988) and are based on spatial normalization to a template provided by the Montreal Neurological Institute (Evans et al., 1994).

*p value corrected for entire brain volume; **pvalue corrected for volume of interest; ***p value uncorrected, only reported because of symmetric significant activation on the right.
