What are false sensory experiences, such as seeing something in the absence of an external visual stimulus?
Hallucinations
What are recurring problems in falling or staying asleep?

Who was the neurologist whose theory suggests that human behavior is influenced by unconscious memories, thoughts, and urges?

Cognitive Neuroscience
What is “rapid eye movement sleep”?
REM sleep
What is a complex neurobiological state that involves the brain, body, and hormones?
Sleep
What is a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings?
Sleep Apnea
What is the sequence of images, emotions, and thoughts passing through a sleeping person’s mind?

What is focusing conscious awareness on a particular stimulus?
Selective Attention
What is the ability of the brain to process multiple stimuli simultaneously?

Alpha Waves
What is the sleep disorder characterized by uncontrollable sleep attacks where the affected person may lapse directly into REM sleep, often at inopportune times?
Narcolepsy
What is the tendency for REM sleep to increase following REM sleep deprivation?
REM Rebound
What is the principle that information is often simultaneously processed on separate conscious and unconscious tracks?

What are the large, slow brain waves associated with deep sleep?
Delta Waves
BONUS: Around how many times do we daydream an hour?
