Part of your brain sleeps even when you are awake, says study
have felt that feeling that your body continues to "sleep", even after some awake time. However, a Stanford University study found that this is not just an impression: part of your brain sleeps, even when you are awake.
Scientists explain that when we sleep, areas of the brain display a certain alertness, and this makes these areas have cycles that are independent of our routine, and can wake and fall asleep in alternating periods compared to the rest of the body.
While we sleep, it is easier to find these brain activities than when we are awake; small regions act in a few seconds or even less. This was the first time scientists have discovered areas with clusters of neurons alternating their states between active and less active. Until then, this had only been noticed in individual neurons.
These changes in the activity levels of the neurons when we are awake may explain why, on some days, we tend to forget things or lose focus.
