Human brain’s parts sleep for shorter periods of time to recharge — resulting in forgetfulness and absent mindedness, a team of researchers have found.
Human brain consists of tiny zones and numerous complex parts comprising of arteries and complicated networks of nerve cells. Among these nerve cells many parts stop working for a very minute period of time and as a result we observe that normally brain stops working and mind goes totally blank for some moments.
Research is carried out in University of Wisconsin’s Electroencephalograms (EEGs) — a special device that detects the activity of neurons in the human brain were used in it.
According to Professor Chiara Cirelli, who is a famous psychiatrist and author of this research says that the activity and nap times of brain can be pre-calculated and used in order to anticipate that one should take rest or avoid a job that requires alertness.
Even before you feel fatigued, there are signs in the brain that you should stop certain activities that may require alertness. Specific groups of neurons may be falling asleep, with negative consequences on performance.
We have seen with EEGs that even while we are awake, we can experience shorts periods of micro sleep.
Some experiments were done on rats, and when they were forced to stay awake for a long time, their brain neurons went off despite of the fact that apparently rats were awake.
Even when some neurons went offline, the overall EEG measurements of the brain indicated wakefulness in the rats.
This shows the importance of sleep for a human brain otherwise neurons can go to sleep hindering the daily routine very badly.
Research says that these sleepy neurons are situated in the motor cortex part of the brain which is solely responsible for carrying out the tasks of human body. Part is that this sleep activity happens in a very minute quantity of cells approximately at 10-20% of a neuron zone.
This research is published in Journal called nature and is widely being classified as a vitally useful work in determining the behavior of human brain.
