Gender differences were observed in two clusters, one encompassing the dorsal visual stream and the other the ventral visual stream during the Calculation, compared to the Identification task (p < .01, corrected for multiple spatial comparisons at p < 0.05; cluster extent = 306 voxels). Localization of brain activation in the two clusters are shown, along with the corresponding Brodmann Area (BA), significance level of the cluster, effect size indicated by Cohen’s d value, the number of voxels in the cluster, the Z-score of the peak activated voxel, and the MNI coordinates.
