Fight On Or Give Up? It Comes Down To 1 Brain Circuit
Scientists studying fish found one brain circuit that predicts the winner and loser of a fight, and humans have the same circuit.By Evan Thomas | March 31, 2016
Lots of animals fight, from big predators all the way down to fish. But it turns out winning and losing could have less to do with brawn and more to do with one specific part of the brain.
Studying zebra fish, which feud for tank space, scientists found a brain structure called the habenula that determines the outcome of a fight.
In that structure, they found two pathways: one that's more active in fish that eventually win fights and one that's more active in fish that lose.
