From ghosts to bats
When research on so-called diencephalon synchronization appeared in the 2000s, some scientists claimed to find evidence of the wonders of parapsychology, ghosts, the afterlife, and other paranormal phenomena in the 1960s and 70s. I rejected it as a field.
For example, in 1965 there were two ophthalmologists Release An absurd study of 15 pairs of prestigious journals of identical twins, Science. Each twin with electrodes on the scalp was placed in a separate room and was asked to blink on command. Studies have shown that in two of the pairs, one twin showed a characteristic pattern of brain activity when the siblings blinked in the other room. Doctors called it “extrasensory induction.”
“This treatise is hilarious,” said Guillaume Dumas, a social physiologist at the University of Montreal, who has been studying brain-to-brain synchronization for over a decade. In the distant era, he said, “there were many treatises with methodologically questionable conclusions claiming to demonstrate diencephalic synchronization with the two.”
However, since then, many healthy studies have shown that brain synchronization emerges between human interactions. Collect and merge data from two brain scanners At the same time the two played a competitive game. This allowed researchers to observe how both brains reacted to each other and were activated. In a 2005 scientific paper, this “hyperscan” technique showed a correlation between the activities of the two brains. I played the game based on trust..
In 2010, Dr. Dumas used scalp electrodes and discovered that two people voluntarily used scalp electrodes. Imitated the movement of each other’s hands, Their brains showed a pattern of combined waves. Importantly, there was no external metronome. musics Or Turn-taking game — It spurred the pair to “tune in” with each other. It happened naturally in the process of their social interaction.
“There is nothing telepathic or creepy,” said Dr. Dumas. Interacting with someone else is complex and requires a continuous feedback loop of attention, prediction, and reaction. Scientists still know little about how that happens, but it makes sense that the brain has some way of mapping both sides of its interaction (your behavior and that of others) at the same time. ing.
