Research indicates that the stronger your social connections the healthier and longer you may live. Scientific studies show that your brain is not just a passive device, disconnected from other brains, alone in the world. You are literally on the same wave-length with people in your life.
Here are excerpts from two interesting studies:
Students Syncing up
“On 11 days over the course of one semester, researchers hooked up all 12 of the students in a biology class to portable devices called electroencephalograms (EEGs) that measured their brain waves.”
The more synced up a student’s brain waves were with the brain waves of the rest of the students in the class, the more likely that person was to say that he or she enjoyed the class that day. For example, when the researchers analyzed brain waves called alpha waves, they found that students’ waves were more likely to rise and fall at the same time as other students’ waves when they were highly engaged in the class
Likewise, when a student’s brain waves were less synced with those of the rest of the class, the student was less likely to say that he or she was engaged.
“How well our brain waves sync up with those of another person appears to be a good predictor of how well we get along and how engaged we are,” lead study author Suzanne Dikker, a psychology research scientist at New York University”.
Monkey See, Monkey Sync
“New tools which involve electrodes implanted into the brains of animals can probe the brains of living animals while they are engaged in social interactions, providing insights into how the brain controls certain behaviors.”
These tools have also revealed that brains likely don’t operate in isolation. There is biological evidence that two minds really can be on the same wavelength.
“What could be more social than brains acting in sync? Similar brain activity may be fundamental for how animals, including humans, interact to form social bonds, according to Dr. Miguel Nicolelis, a professor of neuroscience at Duke University School of Medicine in North Carolina.”
“Nicolelis’ group built an experiment in which one monkey drives a vehicle to get a fruit reward while another monkey watches. Each time the driver monkey gets a fruit reward, the spectator monkey gets one, too. So they are linked, Nicolelis said during the news conference.”
“To our shock, what we found is that as these animals are interacting … both brains are highly synchronized,” Nicolelis said. “We have, in fact, in some instances, 60 percent of [the firing of neurons] in the motor cortexes of both monkeys [happening] precisely the same time.”
The synchronicity became more precise as the monkey got closer to the fruit reward or, as shown during a second experiment in the study, as the spectator monkey helped control the vehicle remotely, Nicolelis said. The finding suggests that the optimal performance of social tasks, such as gathering food, requires synchronization of brain activity across the brains of all subjects involved — in other words, with everyone being on the same wavelength.
Conversely, Nicolelis said that some antisocial neurological disorders, such as autism, may result in an inability to establish such interbrain synchronization. He said he hopes to test this in his lab with human subjects.
“We’re beginning to see a striking aspect of the brain … that brains are wired for social interactions,” said Dr. Robert Green, a professor of neuroscience and psychiatry at the University of Texas Southwestern Medical Center.
Do you wonder if your brain syncs up with animals too?
