Overlap in brain activation across males and females during Calculation, compared to the Identification, condition (p < 0.01), as assessed using a conjunction analysis. The three major activation peaks in each cluster are shown with their corresponding Brodmann Area (BA), significance level of the cluster, the number of voxels in the cluster, the Z-score of the peak activated voxel, and the MNI coordinates.
