Explanation / Answer

40.a) acetylcholine neurons

Aggregates of hyperphosphorylated tau proteins and neurofibrillary tangles increase in the case of Alzheimer's.

41. d) hypnogogic hallucinations during the waking state.

REM sleep is characterised by hallucinations.

42. c) sleep apnea

43. b) sudden loss of muscle tone.

cataplexy is a condition of sudden weakening of muscles followed by full consciousness.

44. a) REM sleep

46. a) EEG

EEG is used to measure the brain activity during REM sleep.
