Scientists used artificial intelligence (AI) to uncover distinct patterns of brain organization in men and women. The study around 1,500 brains and trained an AI model to predict the sex of the brain owner 90% accuracy. The researchers focused on three brain networks that are involved in self-referential processing, reward response, and emotion regulation. They found that these networks showed consistent sex differences in their connectivity and activity. The study’s lead author, Vinod Menon, PhD, said that sex plays a crucial role in human brain development, aging, and the manifestation of psychiatric and neurological disorders. He added that identifying sex differences in the healthy adult brain is a critical toward understanding sex-specific vulnerabilities in these conditions. The study some recent claims that there are no biological differences between men and women, especially in the context of transgender issues. However, some critics have whether the observed differences are due to biological or social factors, or a combination of both.
