When people agreed, their brain activity was harmonious and tended to be focused in sensory areas of the brain such as the visual system, possibly in response to social cues from the other person, according to the authors.
When people disagreed, sensory areas of the brain were less active while there was increased activity brain areas that handle higher order executive functions, such as reasoning.
\”There is a synchronicity between the brains when we agree,\” Hirsch said in a university news release. \”But when we disagree, the neural coupling disconnects.\” She noted that in discord, the two brains engage many emotional and thinking resources \”like a symphony orchestra playing different music.\”
The study was published Jan. 13 in the journal Frontiers of Human Neuroscience.
Understanding how our brains function while disagreeing or agreeing is important as the United States faces sharp political divisions, according to Hirsch.
