Sex differences in the human brain are of interest for many reasons: for example, there are sex differences in the observed prevalence of psychiatric disorders and in some psychological traits that brain differences might help to explain. We report the largest single-sample study of structural and functional sex differences in the human brain female, male participants; mean age Males had higher raw volumes, raw surface areas, and white matter fractional anisotropy; females had higher raw cortical thickness and higher white matter tract complexity. There was considerable distributional overlap between the sexes. Subregional differences were not fully attributable to differences in total volume, total surface area, mean cortical thickness, or height.

Neuroscience of sex differences

Pop neuroscience has long been fascinated with uncovering secret biological differences between male and female brains. The question of whether men and women have innately different brains rarely fails to get people riled up. Just last year, the Google engineer James Damore caused an uproar after publishing a manifesto detailing the various ways women were biologically different from men. It seems to depend on what exactly is being measured. For example, a large study in the U. What does that mean for how the brain works? Eliot said that Damore has a misunderstanding of neuroscience and that his letter overstated the role of testosterone in male and female bodies.

Are Male and Female Brains Biologically Different?

Do men and women have different brains? Previous neuroimage studies sought to answer this question based on morphological difference between specific brain regions, reporting unfortunately conflicting results. In the present study, we aim to use a deep learning technique to address this challenge based on a large open-access, diffusion MRI database recorded from 1, young healthy subjects, including men and women healthy subjects. The proposed 3D CNN was applied to the maps of factional anisotropy FA in the whole-brain as well as specific brain regions. The entropy measure was applied to the lowest-level image features extracted from the first hidden layer to examine the difference of brain structure complexity between men and women. The proposed 3D CNN yielded a better classification result

Are Male and Female Brains Biologically Different?

On a gray day in mid-January of , Lawrence Summers, then president of Harvard University, suggested that innate differences between the male and female brain might be one factor underlying the relative scarcity of women in science fields. His remarks reignited a debate that has been smoldering for a century, ever since some scientists sizing up the brains of both sexes began using their main finding—that female brains tend to be smaller—to bolster the view that women are intellectually inferior to men. To date, no one has uncovered any evidence that anatomical disparities might render women incapable of achieving academic distinction in math, physics or engineering [ see box on page 11 ]. And the brains of men and women have been shown to be quite clearly similar in many ways. Nevertheless, over the past decade or so investigators have documented an astonishing array of structural, chemical and functional variations in the brains of males and females.
