- 2. waves the large, slow brain waves associated with deep sleep.
- 3. non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep.
- 6. the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.
- 8. false sensory experiences, such as seeing something in the absence of an external visual stimulus.
- 10. 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.
