Brain 'never sleeps' when a person goes to bed

Even when a person is asleep in bed, there is still activity taking place in their brain, scientists have claimed.

According to Softpedia, it has previously been thought that the brain enters a hibernation-like state when a person is sleeping in bed.

This means their senses can only be activated by outside stimulus of the body's internal clock.

However, researchers have now discovered that slow electrical changes do exist in the brain, even when the body is in the deepest stages of sleep, although they are uncertain why this occurs.

Yuval Nir, a neurobiology student at the Weizmann Institute, involved with the study, said: "In the old approach, the senses are 'turned on' by the switch of an outside stimulus.

"This is giving way to a new paradigm in which the brain is constantly active and stimuli change and shape that activity."

The Sleep Council explains that a good night's rest in bed is essential as it helps people to remain alert and refreshed throughout the day.
