On a sagittal section, it is oval in shape, having a long vertical diameter that measures about 5 mm.
In 1991 brain studies performed by Laura Allen and Roger Gorsky of UCLA noted that the Anterior Commissure was found to be 1/3 larger in men with a homosexual orientation.
Its fibers can be traced laterally and backwards on either side beneath the corpus striatum into the substance of the temporal lobe.
