Across
- 3. a chemical substance that alters perceptions and moods
- 7. drugs that excite neural activity and speed up body functions
- 8. drugs that depress central nervous system activity, reducing anxiety but impairing memory and judgement
- 10. psychedelic drugs such as LSD that distort perceptions and evoke sensory images in the absence of sensory input
- 12. our subjective awareness of ourselves and our environment
- 15. a social interaction in which one person suggests to another that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
- 19. our biological clock; regular bodily rhythms that occur on a 24 hour basis
- 20. a periodic natural loss of consciousness as distinct from unconsciousness resulting from a coma, anesthesia, or hibernation
- 21. the major active ingredient in marijuana; triggers a variety of effects including mild halluncinations
- 22. a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep often at inopportune times
- 23. a sequence of images, emotions, and thoughts passing through a sleeping person's mind
- 26. the underlying meaning of a dream
- 27. bizarre experiences such as jerking or a feeling of falling or floating weightlessly while transitioning to sleep
- 28. a stimulating and highly addictive psychoactive drug in tobacco
- 31. the tendency for REM sleep to increase following REM sleep deprivation
- 32. a stimulant and mild hallucinogen that produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition
- 34. a disorder characterized by continued substance craving and use despite significant life disruption and/or physical risk
- 36. a powerfully addictive drug that stimulates the central nervous system with accelerated body function and associated energy and mood changes; over time appears to reduce baseline dopamine levels
- 37. a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings
- 38. rapid eye movement sleep; a recurring sleep stage during which vivid dreams commonly occur. The muscles are mostly relaxed but other bodily systems are active
Down
- 1. a split in consciousness which allows some thoughts and behaviors to occur simultaneously with others
- 2. an altered state of consciousness reported after a close brush with death, often similar to drug-induced hallucinations
- 4. Alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use
- 5. the relatively slow brain waves of a relaxed awake state
- 6. the large slow brain waves associated with the deep sleep of NREM-3
- 9. a pair of cell clusters in the hypothalamus that controls circadian rhythm. In response to light, the SCN causes the pineal gland to adjust melatonin production, thus modifying our feelings of sleepiness
- 11. a powerful and addictive stimulant derived from the coca plant; produces temporarily increased alertness and euphoria
- 13. the diminishing effect with regular use of the same dose of a drug requiring the user to take larger and larger doses before experiencing the drug's effects
- 14. remembered storyline of a dream as distinct from its latent, or hidden, content
- 16. the discomfort and distress that follow discontinuing an addicting drug or behavior
- 17. 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
- 18. terrors a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terrors occur during NREM-3 sleep within 2-3 hours of falling asleep and are seldom remembered
- 24. opium and its derivatives, such as morphine and heroin; depress neural activity, temporarily lessening pain and anxiety
- 25. drugs that reduce neural activity and slow body functions
- 27. false sensory experiences such as seeing something in the absence of an external visual stimulus
- 29. recurring problems in falling or staying asleep
- 30. non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep
- 33. a powerful hallucinogenic drug, also known as acid
- 35. a drug that stimulates neural activity, causing accelerated body functions and associated energy and mood changes
