Brain "code" marks where you go

as new cases of coronary pneumonia increase, distance from others has never been more important. A new study from the University of California, Los Angeles, recently showed that the human brain produces a common code to mark its relationship with them. The study was published in Nature in December 2020.
we looked at how people react when they are in a physical space (first individually, then with others). The study's author, Nanthia Suthana of the Institute of Psychiatry at the David Geffen School of Medicine at the University of California, Los Angeles, said. Suthana's lab studies how the brain forms and recalls memories.
our study shows that when we are in a place to think about others, the brain produces a universal label. She added.
Suthana and colleagues looked at people with epilepsy, and their brains were surgically implanted early to control seizures. The electrodes are located in the inner temporal lobe, the center of the memory-related brain and are thought to regulate navigation, much like GPS devices.
study has shown that low-frequency brain waves produced by neurons in the inner temporal lobe can help rodents track their location as they navigate new places. Mattias Stangl, lead author of the study and a postdoctoral student at Suthana Labs, said, "We wanted to study the idea in people and see if they could monitor the people around them, but that idea was hampered by existing technology."
a $3.3 million prize from the Brain Project at the National Institutes of Health, the lab invented a special backpack containing a computer that can wirelessly connect to brain electrodes. This allowed her to conduct research while the subjects were moving freely, rather than just lying motionless in a brain scanner or connected to a recording device.
the experiment, each patient was asked to carry a backpack and was asked to explore an empty room, find a hidden place, and remember it for future search. As they walk, backpacks record their brain waves, eye movements, and paths through the room in real time.
when participants searched the room, their brain waves flowed in a unique pattern, suggesting that each person's brain drew walls and other boundaries. Interestingly, when patients sit in a corner of the room and watch others approach their hidden positions, their brain waves flow in a similar way.
findings suggest that people's brains produce the same patterns to track our location in shared environments with others. "Daily activities require us to constantly deal with other people in the same place." "Consider choosing the shortest airport security line, finding a seat in a crowded parking lot, or avoid bumping into someone on the dance floor," Suthana said. At
, the UCLA team also found that what people are concerned about may affect the way the brain maps locations. For example, when patients look for a hidden location, or when they see another person approaching the location, their brain waves flow more powerfully than when they simply explore the room.
"s findings support the idea that this brainwade pattern can help us identify boundaries in a particular mental state. Stangl says, for example, when people focus on a goal and look for something.
future research will explore how people's brain patterns respond in more complex social situations, including outside the lab. The UCLA team has provided the backpack to other researchers to speed up the discovery of brain and brain diseases. (Source: Feng Weiwei, China Science Journal)
