Women’s brains act younger than men’s
When it comes to the battle of the brains, ladies rule.
A new study reveals that female brains, on average, act nearly four years younger than their chronological age, while men’s brains act more than two years older.
The study, in Proceedings of the National Academy of Sciences, used positron emission tomography scans to measure the flow of glucose and oxygen in subjects’ brains. The brain needs sugar as fuel. How it metabolizes glucose indicates a great deal about its metabolic age.
Scientists hope to learn if brain metabolic differences play a protective role for women, who tend to score higher on problem-solving and cognitive tests for reason and memory.
