The Restoration Theory of Sleep suggests that the body and brain restore themselves during sleep. According to this theory, REM sleep is essential for brain restoration, while SWS (stages 3 and 4) is crucial for body restoration. Oswald's research on patients with CNS damage and overdose patients showed increased REM sleep, suggesting it might be for brain tissue growth. Newborn babies also exhibit more REM sleep due to their rapid brain growth. Sleep is also important for conserving neurotransmitters, which are chemical messengers that carry electrical signals from neuron to neuron. During REM sleep, neurotransmitters are replenished for use during wakefulness. Horne labeled SWS and REM as 'core sleep,' believing that brain repairs occur during this stage. However, he also suggested that restoration can take place during wakeful rest.

They suggested NEW TISSUE GROWTH occurs during sleep.
It was suggested that; REM SLEEP โ the brain restores itself SLOW WAVE SLEEP (stages 3 and 4 ) โ the body restores itself.
Found in patients with damage to their CNS (spinal cord/brain) and patients who have taken an overdose (that may have damaged the brain) that they engaged in more REM sleep than normal subjects.
As we go through the day, the amount of NEUROTRANSMITTERS in our bodies DECREASES. REM Sleep replenishes NEUROTRANSMITTERS for use during wakefulness
Oswald ( 1969 ) โ 5 MINUTES
Horne ( 1988 ) labelled SLOW WAVE SLEEP (SWS) and REM as โCORE SLEEP.โ He stated that during this stage, brain repairs for vital functioning.
Shapiro et al (1981) Researcher marathon runners โ slept for about an hour more for TWO NIGHTS. SWS increased โ SUPPORT OR CONTRADICT THEORY? Horne and Minard (1985) โ put participants through exhausting tasks โ went to sleep quicker but did not sleep for longer.
๏ Theory says NEUROTRANSMITTERS ARE INCREASED. Think about what you know about brain activity during sleep, especially REM. Would this be the case? ๏ Horne (1988) AMINO ACIDS (what make up proteins) are only available for 5 hours after a meal. ๏ Therefore do you think PROTEIN SYNTHESIS (making proteins) would be possible during sleep?
