The comments of Diana Sidtis are gratefully appreciated. Do women really have more bilateral language representation than men? Sexual dimorphism in the human corpus callosum: its evolutionary and clinical implications. As brain sex differences corpus callosum ultrasound in Norfolk, there was also a significant linear tendency for the CCA to decrease with age.

In particular, future studies are needed that relate macro- and microstructural CC morphology to behavior and functional and structural brain asymmetries. To automatically find the CC on a test image: We segmented all scans in our cohort using this method.

Therefore, a large sample size is required to demonstrate a significant gender difference. A rectangular bounding box was defined on the midsagittal slice that contained the CC.

A novel approach for modeling neural responses to joint perturbations using the NARMAX method and a hierarchical neural network. Evolving knowledge of sex differences in brain structure, function, and chemistry. We performed DTI data preprocessing includes format conversion, b0 image extraction, brain extraction, eddy current correction, and tensor FA calculation.

In the final step we use dtifit to calculate the tensors to get the FA, as well as mean diffusivity MD , axial diffusivity AD , and radial diffusivity RD values. In contrast, for the corpus callosum, there was a pattern of reduced radial as well as increased axial diffusivity which suggests both increased myelination and higher axonal quality Song et al.

It can reflect alterations in various tissue properties including axonal size, axonal packing density, and degree of myelination Chung et al. A map was then obtained based on the classification accuracies of different ROIs to show their distribution in the brain.

This quantitative MRI study reports measurement of corpus callosum area taken from midsagittal brain images in 51 healthy men and 41 healthy women, spanning the adult age range (22 to 71 years). Men had larger brains and corpora callosa than women, but callosal size did not correlate with age in either by:
