RESTORATION THEORY OF Sa a 5 MINUTES 1) According the RESTORATION THEORY, what is the function of SLEEP? 2) What did Adams and Oswald (1983) theorise? (What is REM sleep for?) What is SWS for? It was suggested that; REM SLEEP – the brain restores itself SLOW WAVE SLEEP (stages 3 and 4) – the body restores itself. 5 MINUTES 3) Describe OSWALD (1969) and his research into patients with CNS damage and patients who have taken an overdose. 4) How does the sleep of NEWBORN BABIES support the theory that REM sleep is for GROWTH OF BRAIN TISSUE? OSWALD (1969) 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. 5 MINUTES 5) What effect does sleep have on our levels of NEUROTRANSMITTERS? It is also suggested that sleep is an important way of CONSERVING NEUROTRANSMITTERS. What are NEUROTRANSMITTERS? They are CHEMICAL MESSENGERS which carry ELECTRICAL SIGNALS from neuron to neuron. They are important to keep us alert and for our body to function. SLOW WAVE SLEEP It is hypothesised this is necessary for RESTORATION of the BODY. During this stage of sleep GROWTH HORMONE is released. This stimulates PROTEIN SYNTHESIS i.e. Production of new body tissue. HORNE (1988) – 5 MINUTES What did HORNE label SWS and REM sleep? Why does Horne state this sleep is important? What does HORNE label stages 1 and 3 of sleep? HORNE (1988) Horne (1988) labelled SLOW WAVE SLEEP (SWS) and REM as ‘CORE SLEEP.’ He stated that during this stage, brain repairs for vital functioning. WHAT IS BEING RESTORED?  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? FFI MICHAEL CORKE SLEEP DEPRIVATION STUDIES How would such studies add to the argument? PETER TRIPP RANDY GARDNER A02 – RANDY GARDNER and PETER TRIPP? Case studies……(ELABORATE) Lack of control…….(ELABORATE) May have been experiencing MICRO- SLEEP…………(ELABORATE) REM and DEPRESSION What is the purpose of REM according to the theory?  Studies into individuals with depression suggests LACK of REM SLEEP has positive consequences. WU ET AL (1999) – symptoms of depression are reduced in people DEPRIVED of REM.
