Humans are social beings and often understand each other quite well; however, we still only have a limited knowledge of the brain mechanisms that underlie this astonishing ability. To better understand this, Stolk et al. scanned the brains of pairs of people that worked together to complete a specific task by communicating only through a visual display. The participants' brain activity synchronized in an area called the right superior temporal gyrus when they completed familiar but not unfamiliar tasks. These results suggest that establishing mutual understanding relies on spatially and temporally coherent brain activity between the two people communicating.
