Sleep walking is a disorder of ------- - a person who's sleep walking is partly awake in the sense that they're engaged in activities normally associated with the waking state, but they're also asleep.
Arousal

Sleep walkers are in a deep sleep (SWS) which means that it's very --------- to rouse the sleep walker.
Difficult

Recordings of brain activity made during sleep walking show a mixture of delta waves typical of SWS and beta waves which are characteristic of the ----- state - SW occurs when someone in deep sleep is awakened but arousal of the brain is incomplete.

The fact that risk factors trigger sleep walking in only some people suggests that some individuals may have an --------- vulnerability for sleep walking.
Inherited

One possibility for why sleep walking is more common in childhood is that it happens because children have ---- SWS than adults.

Who suggested that that system that normally inhibits motor activity in SWS isn't sufficiently developed in some children & it may also be underdeveloped in some adults?

Who examined the motor excitability of adult sleepwalkers during wakefulness & found, compared to normal controls, the sleepwalkers had signs of immaturity in the relevant neural circuits?

Who found the prevalence of sleep walking in 1st degree relatives (parents, siblings & children) of an affected subject is at least 10 times greater than that in the general population?

Who reported about 50% concordance in identical (MZ) twins compared to 10-15%% in DZ twins, and also identified a gene that may be critical in sleep walking (the DQB1*05 gene)?

The diathesis-stress model proposes that genes merely provide a ------------- (diathesis) for a disorder but the disorder only occurs in situations of environmental stress, which seems likely in the case of sleep walking.
Vulnerability

Who studied people who were referred to a sleep lab for suspected SW? In the lab participants were prevented from falling asleep. 1st night = 50% showed signs of SW. 2nd night = 90%. Sleep deprivation doesn't lead to SW & was acting as a 'stressor'.
Zadra et al

The diathesis-stress model can also explain the higher frequency of sleep walking in -------- - the higher levels of SWS in childhood acts as a diathesis, so that children are more likely than adults to have episodes of sleep walking.

1 belief about SW is that it results when a person acts out dreams representing repressed traumas & anxieties but the fact that SW occurs during ---- (SWS) sleep means it's unlikely to be associated with dreaming.
