Areas of increased GM concentration in heterosexual women compared to homosexual women.

<p>Regional differences in GM concentration are characterized by the cluster extent, stereotactic MNI coordinates and T-value of the voxel showing the peak difference. P-values were corrected by the False Discovery Rate. R = right; L = left.</p

Mean GM, WM, and CSF volumes (ml) of heterosexual and homosexual men and women.

<p>Mean volume values as delivered by SPM segmentation algorithm.</p><p>GM = grey matter, WM = white matter, CSF = cerebrospinal fluid.</p

Heterosexual men and homosexual women compared to heterosexual women.

<p>Areas of decreased GM concentration in heterosexual men are shown in blue and areas of decreased GM concentration in homosexual women are shown in yellow (p<0.05; FDR corrected, sagittal section at x = −29). Reduced GM concentration of homosexual women (relative to heterosexual women) is located within a sex dimorphic brain area.</p

Areas of increased GM concentration in heterosexual women compared to homosexual women.

<p>Coronal sections from y = 8 to y = −6 (p<0.05; FDR corrected). Left brain side is to the left.</p
