Sex Differences in the Principal Orientation of Corpus Callosum on Midsagittal Plane

Abstract

We investigated sex differences in the corpus callosum measured by MRI on the midsagittal plane using Fourier descriptors and central moments. In the result, we showed that females tend to have stooping corpus callosum relative to males at significance level 10-¹⁷%. The finding suggests that there may exist sex differences in the callosal configurations in cranium rather than in the shape and/or size of the corpus callosum.
