Across
- 3. Rhythm the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle
- 4. a sleep disorder characterized by uncontrollable sleep attacks. The sufferer my lapse directly into REM sleep, often at inopportune times
- 7. a cluster of neurons in the hypothalamus in the brain that governs the timing of circadian rhythms
- 8. Suggestion a suggestion, made during a hypnosis session, to be carried out after the subject is no longer hypnotized; used by some clinicians to help control undesired symptoms and behaviors
- 9. according to Freud, the underlying meaning of a dream
- 12. Dependence a psychological need to use a drug, such as to relieve negative emotions
- 13. drugs that reduce neural activity and slow body functions
- 16. our awareness of ourselves and our environment
- 17. false sensory experiences, such as seeing something in the absence of an external visual stimulus
- 18. the discomfort and distress that follow discontinuing the use of an addictive drug
- 19. the diminishing effect with regular use of the same does of a drug, requiring the user to take larger and larger doses before experiencing the drug's effect
- 22. a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings
- 23. recurring problems in falling or staying asleep
- 30. a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terrors occur during Stage 4 sleep, within two or three hours of falling asleep, and are seldom remembered
- 31. the major active ingredient in marijuana; triggers a variety of effects, including mild hallucinations
- 32. a powerfully addictive drug that stimulates the central nervous system, with speeded-up body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels
- 34. a physiological need for a drug, marked by unpleasant withdrawal symptoms when the drug is discontinued
- 35. Neurotransmitter
- 37. a powerful hallucinogenic drug; also known as acid
Down
- 1. according to Freud, the remembered story line of a dream
- 2. a social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
- 5. compulsive drug craving and use, despite adverse consequences
- 6. drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgment
- 10. a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood cognition
- 11. opium and its derivatives such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety
- 12. a chemical substance that alters perceptions and moods
- 14. the large, slow brain waves associated with deep sleep
- 15. drugs that excite neural activity and sped up body functions
- 20. psychedelic ("mind-manifesting") drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input
- 21. non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep
- 24. a split in consciousness, which allows some thought and behaviors to occur simultaneously with others
- 25. A hormone manufactured by the pineal gland that produces sleepiness.
- 26. the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakenings during REM sleep)
- 27. drugs that stimulate neural activity, causing speeded-up body functions and associated energy and mood changes
- 28. an altered state of consciousness reported after a close brush with death; often similar to drug-induced hallucinations
- 29. rapid eye movement sleep; a recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active
- 33. the relatively slow brain waves of a relaxed, awake state
- 36. a sequence of images, emotions, and thoughts passing through a sleeping person's mind. Dreams are notable for their hallucinatory imagery, discontinuities, and incongruities, and for the dreamer's delusional acceptance of the content and later difficulties remembering it
