How is the brain affected by lack of sleep?
Scientists measuring sleepiness have found that sleep deprivation leads to lower alertness and concentration. It’s more difficult to focus and pay attention, so you’re more easily confused. This hampers your ability to perform tasks that require logical reasoning or complex thought. Sleepiness also impairs judgment.

Does sleep deprivation cause permanent brain damage?
At a more advanced level, sleep deprivation can over-stimulate parts of the brain and even lead to permanent brain damage, according to a report on sleep deprivation among students published by The Guardian. “This is because of the brain’s ‘neural plasticity’ – which means its ability to adapt to new situations.

Which of the following are happening during stages 3 and 4 of sleep?
In stage 3, extremely slow brain waves called delta waves begin to appear, interspersed with smaller, faster waves. By stage 4, the brain produces delta waves almost exclusively. It is very difficult to wake someone during stages 3 and 4, which together are called deep sleep.
What are the stages of sleep deprivation?
There are generally thought to be five stages of sleep deprivation, which, as they progress, have growing repercussions. Stage 1 of sleep deprivation is one night or 24 hours without sleeping.

What happens to your brain in the deep sleep stage?
In the deeper sleep stages (stage 3 and 4) you enter into a near coma-like state, during which physiological cleansing and detoxification processes in the brain take place. Once in REM sleep the eyes will dart back and forth quickly under the eyelids and the brain will become stimulated allowing for increased mental fortitude and memory formation.
