Elaborate Hour Sensitive Brain Makes Us Against Time

Clockwise position and the position of the sun in the sky going by itself, yet somehow, people can figure out how much time has passed. A recent study revealed the reasons behind such capabilities. The study revealed that the brain does not have guidelines for hours, but more than that, each of the circuits of the human brain can learn to explain the time.

"People will think of when they need to give time to something, there is some clock circuit in the brain that can give us clues," said study author, Geoffrey Ghose, who is also a scientist who studied the nerve at the University of Minnesota.

"What we have indicated in the study actually very different. For each task, mild action and decision you make, you have the potential to be able to develop a picture of the time. "Sensitive sense of time is very fundamental for living, says Ghose told LiveScience.

"Often times you use the directions as well as events from the outside to find out the current time, like when you look out and see where the position of the sun, or look at the clock," says Ghose. "But you have a sense of time that does not depend on all these things."

To see how the brain keeping time, the researchers trained two monkeys to be able to move the eyes from side to side in a very accurate manner. The room where the monkeys are not having a clue from the outside to help the monkeys know the time.

"They basically do as well as a metronome to move the eye to the right and to the left," says Ghose.

Then, Ghose and colleagues used electrodes implanted into the brains of monkeys to measure electrical signals from neurons, or brain cells, in the parietal corte, which is part of the brain associated with eye movements.

Approximately 100 neurons work to keep the eye movements of monkeys in a timely way, said Ghose. When the monkeys had to move their eyes, sinyak electrically arises, then gradually declined until the monkey was looking in another direction. The researchers believe that the electrical activity gradually decreased a typical signal to determine the time.

Interestingly, the researchers did not think that 100 is the timing of the neurons in the brain. Instead, Ghose and colleagues concluded that the brain can learn the internal sense of time for all activities, both to meet friends to go drinking coffee or playing the piano.

"Every small circuit for any mild activity can develop the ability to know the time," says Ghose.

Because the internal sense of time can be learned, they are often late may not be able to blame their internal clock error, he said.

"Maybe with enough practice, it is important for one to be able to develop kepakaan very good time," he said. "People who do not have a good sense of time, it has been decided that the sensitivity is not important or valuable."
