(biological clock). Usually when deprived of sleep, often show signs of depression, difficualties in learning new informatuon, paying attention, and slowed reaction times. 5. 2 identify the different stages of sleep and the neural activity and dreaming behaviours that occur in each (text p. 176); Stage 1- light sleep, lasts 5- 10 minuts, our brain activity powers down by 50% or more, producing theta waves, which occur 6-7 times per second. These waves are slower than beta waves of 13 or more times per second produced during active alert states and the alpha waves of.
