Restoration Explanations

1. Growth hormone is secreted during SWS (stimulates growth & is thus important during childhood - also important in adulthood as it enables ------- synthesis & cell growth to take place. (7)
5. Who woke sleeping volunteers as soon as their eyes started to dart about and found that they had an increased tendency to go into REM sleep when they went back to sleep and, on recovery nights, the amount of time in REM increased (50%)? (6)
6. Who found that, when sleep-waking cycles are reversed by 12 hours (person goes to sleep in morning and gets up at night), the release of GH with sleep is also reversed? Shows that GH release is controlled by neural mechanisms related to SWS. (6, 2, 2)
7. Who suggests that the more we know about the sleep patterns of other species the more it becomes apparent that environmental pressures rather then restoration provide the key to understanding sleep? (5)
10. Who suggested the amount of REM sleep in any species is proportional to the immaturity of the offspring at birth? (the platypus is immature at birth & has 8 hours of REM sleep a day, whereas the dolphin can swim from birth & has almost no REM sleep). (6)

2. The effects of partial sleep deprivation may lead to what's called 'REM -------' - the need for more REM sleep after a night deprived of REM sleep. When someone's deprived of sleep there's not the same effect, it only appears related to REM & SWS. (7)
3. Who demonstrated SWS rebound effects using acoustic stimulation which suppresses all SWS sleep by arousing a participant whenever their EEG appears to be going into deep sleep/SWS? (7, 2, 2)
4. A second consequence of 'sleep as restoration' is that increased physical exercise should lead to --------- sleep in order to restore the proteins and biochemicals used, which appears to be the case in some studies. (9)
8. The study of sleep deprivation is generally restricted to case studies/observational studies of a small group of participants - the main difficulty with this is that such participants are likely to be ------. (6)
9. Research found that the amount of growth hormone released correlates with the amount of --- & the decline of growth hormone in older age has also been associated with reduced ---. (3)
