Researchers at Tel Aviv looked at MRI scans of 1,400 brains and concluded that “the brain does not reflect a clear dichotomy based on gender difference,” reported the online Science magazine on November 30, 2015.
The study found that human brains do not fit neatly into “male” and “female” categories. In fact, although researchers have identified several structural differences between the brains of men and women, it’s impossible to tell the sex of an individual based solely on MRI images of the brain.
