Mapped Fruit Fly Brain Powers Bitcoin Trades and Fails at Doom
Software engineers are utilizing the complete male fruit fly central nervous system map containing more than 166,000 neurons to run software and financial tools. A project named Stonkfly uses the brain map to place real Bitcoin trades on Coinbase with $100, though it has not produced profitable results. Meanwhile, the mapped brain has attempted to play Doom over 6,000 times without beating the game. Additional research utilizing the mapping tools reveals that specific brain cells can suppress aggression in both male and female flies, and that neurons construct their identities during their early hours of life rather than inheriting them.
