Syncing our brain activity may help us interact with each other

It's said that imitation is the sincerest form of flattery. Monkeys synchronise their brain activity during social interactions, possibly helping them to learn from each other. Understanding how this might work in humans could help groups of people work together more efficiently. To study brain activity in social situations, Miguel Nicolelis at Duke University Medical Centre, in Durham, North Carolina and his colleagues developed a wireless system that can record the neuronal activity from two monkey brains simultaneously. During the experiment, one monkey was propelled in an electric wheelchair towards a fruity treat, while a second monkey sat across the room and watched.
