Just as sleep onset and maintenance are influenced by a complex soup of neurotransmitters, so waking up involves changes in brain chemical levels and the activity of certain neurons. Norepinephrine, acetylcholine, serotonin, and histamine are among the substances that make major level changes during the wake-up process, and orexins are critical for keeping the brain awake during the day.
From a physiological/EEG point of view, awakening involves a large increase in electrical activity in the cortex. "
