Tiny Fly Brain, Big Clues About Behavior
Researchers mapped 124 million neural connections in a male fruit fly and compared them with females, finding about 5% wiring differences that drive aggression, courtship, and love-song circuits. While 95% of cells are shared, the wiring differences illuminate how genes shape brain wiring to influence behavior, with potential implications for human conditions such as autism and schizophrenia and possible inspirations for AI design.
