Why do people almost never act out their dreams during REM sleep? The major postural muscles are paralyzed during REM sleep. What does it indicate if a sleeper's EEG shows long, slow, high-amplitude waves?
Most neurons are active in synchrony with one another.
In which state will a person be wakeful but not very aware?
A vegetative state
is when a person is awake but showing no signs of awareness. On recovery from the coma state, VS/UWS is characterised by the return of arousal without signs of awareness. In contrast, a coma is a state that lacks both awareness and wakefulness.

What is the difference between persistent vegetative state and minimally conscious state?
Two different aspects must be assessed:
alertness
(wakefulness) and awareness. The persistent vegetative state (PVS) is characterized by a lack of reproducible responses to the environment. As soon as simple responses to the environment are seen, the patient is said to be in a minimally conscious state (MCS).
