The neuroscience of sex differences is the study of characteristics that separate the male and female brain. Psychological sex differences are thought by some to reflect the interaction of genes, hormones and social learning on brain development throughout the lifespan. Some evidence from brain morphology and function studies indicates that male and female brains cannot always be assumed to be identical from either a structural or functional perspective, and some brain structures are sexually dimorphic.

Sex-biased psychophysiology, behavior, brain function, and conditions are extensive, yet underlying structural brain mechanisms remain unclear. There is contradicting evidence regarding sexual dimorphism when it comes to brain structure, and there is still no consensus on whether or not there exists such a dimorphism for brain white matter. Therefore, we conducted a voxel-based morphometry VBM analysis along with global volume analysis for white matter across sex. We analyzed T1-weighted MRI brain images male, female to investigate any differences in white matter WM between males and females.

By Jessica Hamzelou. Doctors could use this information to make a case for delaying puberty to improve the success of a sex change later. Medics are keen to find concrete physical evidence to help those children who feel they are trapped in the body of the opposite sex.

Irvine, Calif. January 20, -- While there are essentially no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence. The study shows women having more white matter and men more gray matter related to intellectual skill, revealing that no single neuroanatomical structure determines general intelligence and that different types of brain designs are capable of producing equivalent intellectual performance.

Here's the introduction to the bookthe chapter about topographic mappingthe chapter about mirror neuronsand my post about the most important idea in neuroscience. Summary : Subtle observable differences exist between male and female brains, but how exactly these relate to differences in behaviour is unknown. Such gender variations in the brain are often exaggerated and misappropriated, not only by the mass media but also by scientists, to reinforce stereotypes and perpetuate myths.

Sexual dimorphism in human brain structure is well recognised, but little is known about gender differences in white matter microstructure. We used diffusion tensor imaging to explore differences in fractional anisotropy FAan index of microstructural integrity. A whole brain analysis of matched subjects 90 men and 45 women using a 1. A region of interest ROI analysis was used to confirm those results where proximity to CSF raised the possibility of partial-volume artefact.
