Chapter 5: Consciousness
1) The pineal gland releases a hormone called melatonin, which is critical to maintaining the
sleep-wake cycle.
Correct: The SCN communicates signals about light levels with the pineal gland. The pineal
gland releases a hormone called melatonin, which peaks at nighttime and is reduced during
wakefulness. Thanks to this system, light is the primary stimulus regulating our circadian
rhythm and it tells us to sleep at night and stay awake for the day.

Objective: Understand how the sleep cycle works.
4) Young children sometimes experience night terrors, which can cause them to wake from
NREM sleep screaming.
Correct: A person experiencing a night terror may call out or scream, fight back against
imaginary attackers, or leap from the bed and start to flee before waking up. Unlike
nightmares, night terrors are not dreams. These episodes occur during NREM sleep, and the
majority of people who experience them typically do not recall any specific dream content.
