Why do memories look like movies? It turns out there are “time cells” in the human brain.

According tomedia reports, if you have fallen off your bike, you may have a movie-like memory: the wind blowing through your hair, the pebbles on the road, and then the pain… The memory is now known as situational memory, and now a team of researchers, published in the Proceedings of the National Academy of Sciences, says researchers have found a cell in the human brain that makes memory possible, called “time cells,” that leave a time mark on memory as it forms, allowing us to recall events or experiences in the correct order.

“By getting time cells to create indexes across time, you can put all your memories together in an understandable way,” said study senior author Dr. Bradley Lega, a neurosurgeon at the University of Texas. “

Dr. György Buzsáki, a professor of neuroscience at New York University, said scientists discovered the presence of time cells in rodents decades ago, but the latest study is crucial because “the ultimate arbiter is the human brain.”

By studying 27 patients preparing for severe epilepsy surgery, Lega and the team found time cells in their brains, where electrodes were placed in the mematic body of the brain and another area of the brain associated with navigation, memory and time perception as part of pre-surgery preparation.

In the experiment, patients studied a sequence of 12-15 words that appeared on a laptop screen for about 30 seconds, and then, after a short break, were asked to recall the words they saw.

At the same time, the researchers measured the activity of individual brain cells and found that a small number of cells triggered at a specific time in each word sequence.

“We found time cells that can mark discrete time fragments in a time window of about 30 seconds,” Legar said. These time fragments seem to help people recall when they saw each word, and in their order, and the brain may remember it in the same way as we re-experience experiences like falling off a bike. “

The findings could help explain why people with damaged sea mass may experience strange memory problems, says György Buzsáki. In one experiment, scientists compared the memories of a group of people who had just completed a trip to the University of California, San Diego that included some stage activities.

All the participants remembered most of the things they did, including locking their bikes, receiving water from the water dispenser, etc., but the people with body damage in the sea mass were unable to arrange these events in the correct order, and the sequence of events disappeared completely from their brains.

New research suggests this is because they don’t have time cells in their brains, and time cells allow them to re-create the whole journey in their brains. “While time cells are critical in creating sequences of events, they really don’t tick at the same rate as the clock does, and instead the ticks of time cells are accelerating or slowing down, depending on emotional factors,” says György Buzsáki. “

‘Every day is very long when you have to wait for the election to vote, and when we ask when the new crown outbreak ends, the same is true, and people are going to spend the day during the outbreak, ‘ says György Buzsáki. But when you’re having a great time, you feel like time is passing fast.
