Scientists from the University of California conducted a study in which they found a “second hand” in the internal clock of the brain. They managed to figure out how the organ works by scolding short time intervals.

The brain's ability to tell time has long been known to biologists. Many living things have a built-in clock. Thanks to them, they feel the approach of the change of day and night or the arrival of the season. However, until recently, there was no information on whether mammals are able to distinguish between short periods. To find out, and at the same time to understand the principle of the biological mechanism, experts conducted an experiment with the participation of laboratory mice. Rodents, each time before serving food, six and three seconds before filling the container, received signals in the form of food aroma. They have learned to determine exactly when food will emerge from the hole. By studying the brains of the rodents, the researchers realized the “second hand” corrects the sequence of neurons' signals. They compared the process to the effect of a falling snake made of dominoes. Each time the short-term periods of their fall are equal, the brain also feels the flow of seconds.
The scientists stated that their discovery is of great value for science. A person's ability to measure time is the cornerstone of many other possibilities. By understanding how this mechanism works and tracking neurons, you can see deviations in time, according to Planet Today.
