“An increasing cadre of neuroscientists is utilizing complex technology — plus some quite complicated mathematics — to catch what happens in 1 mind, two brains, as well as 12 or 15 in a time when their owners are engaged in eye contact, storytelling, joint attention centered on a topic or object, or any other action which needs social give and take,” reports Scientific American. “Though the subject of interactive social neuroscience is in its infancy, the hope remains that distinguishing the neural underpinnings of actual social exchange will change our basic comprehension of communication and ultimately improve education or educate treatment of many psychiatric disorders that involve social impairments.” Here’s an excerpt from the report: [T]he first study to track two brains in precisely the exact same time took place almost 20 years ago. Physicist Read Montague, today at Virginia Tech, and his coworkers put two people in separate functional magnetic resonance imaging (fMRI) machines and observed their brain activity as they participated in a simple competitive game in which one participant (the sender) transmitted a sign about whether they had only seen the color green or red and the other participant (the recipient ) needed to choose if the sender was telling the truth or lying. Guesses resulted in rewards. Montague known as the technique hyperscanning, along with his work proved it was possible to detect two brains at once.
Initially, the guide of Montague was followed mostly by other neuroeconomists instead of social neuroscientists. But the term hyperscanning is now applied to any brain imaging research that involves more than one individual. Use of these methods, a number of them new, made hyperscanning less clumsy and, as a result, much more popular and has broadened the range of experiments that were possible. The report also mentions a study from earlier this season which”used hyperscanning to show that eye contact interrupts the societal brain to empathize with activating the very same areas of every individual’s brain simultaneously: the cerebellum, which helps predict the sensory consequences of actions, and the limbic mirror method, a set of brain areas that become active both once we move any part of the body (including the eyes) and once we observe someone else’s moves”
