A study, published in Cerebral Cortex, suggests that brain androgyny does exist, and it is common. Psychological androgyny is thought to be psychologically protective. Scientists have long argued over how different male and female brains really are. There are many reports of differences between male and female brains in the literature. Other researchers argue that these differences are tiny, and the categories are anything but absolute. One study suggested that, psychologically, most of us are in fact probably somewhere on a spectrum between what we stereotypically consider a male and a female. To test this, a brain continuum was created using a machine-learning algorithm and neuroimaging data. While male and female brains are similar, the connectivity between different brain areas have been shown to differ.
