"We have developed many ways to communicate in the modern world, and we have fewer physical interactions," said Pavel Goldstein, lead author of the study and researcher at the Boulder Neuroscience Laboratory. University of California. But this article illustrates the strength and importance of human contact. "
The first study, which focused on the synchronization of brain waves in the context of pain, shed light on the role that brain-brain coupling can play in the attenuation resulting from touch, or healer touch.
This study is part of a growing body of research that explores a phenomenon called "synergy between people", where people physiologically reflect people living with them.
"I wanted to test this in the lab: can we really reduce pain to the touch, if so, how?" Pursued Goldstein after discovering his daughter by touching her.
He and his colleagues recruited 22 couples between the ages of 23 and 32, who had been together for at least a year and were placed in several two-minute scenarios, and then measured their brain wave activity.
Situations included sitting together without touching each other. Sit together and by hand, sit in separate rooms. They then repeated several scenarios in which the woman suffered from severe arm pain.
The experiment led to the conclusion that the mere presence of each of the two pairs, one with the other, with or without contact, resulted in some synchronization of the alpha-waveform. mu, a wave length associated with the concentration of attention. When they held hands during the pain, their association increased.
These results correspond to those already published in the same study which revealed that heart rate and respiratory synchrony disappeared when male participants could not touch their carbide to reduce their pain.
Goldstein says, "It seems that the pain completely interrupts this synergy between the couples and the back."
Subsequent tests revealed the level of empathy with the male partner, plus their pain coincided with their brain activity. The more their brain is synchronized, the more painful it becomes.
Goldstein pointed out that more studies are needed to obtain more detailed information, but he offered some explanations to his co-authors: emotions can make a person feel a concept that, according to previous studies, can activate reward mechanisms for destruction of the brain.
"A personal touch can blur the boundaries between oneself and others," the researchers wrote.
