AI Shows Promise in Distinguishing Male and Female Brains
-
An AI can distinguish between male and female brain scans with around 90% accuracy using a new technique called dynamic functional connectivity fMRI.
-
The AI was trained on brain scan data from 1,000 people and tested on scans from two additional groups totaling 400 more people.
-
The AI focuses on patterns of activity and connectivity between different brain regions rather than just brain size.
-
The technique may help explain why some medical conditions and types of neurodiversity differ between the sexes.
-
More testing is needed on larger, additional datasets to confirm the 90% accuracy level across diverse groups.
