Poker players rely on a special region of the brain, as well as a poker face, when deciding whether to bluff or call, according to Duke University research made public Thursday.
As proof, the region reacted differently when someone was playing a human or a computer.
The research could be used in learning more about human emotions such as empathy. Researchers observed the neural reactions of people competing at a poker game, both against a computer and against an opponent the participants knew to be human.
