1

consciousness

our awareness of ourselves and our environment

2

hypnosis

a social interaction in which one person (the subject) responds to another person's (the hypnotist's) suggestions that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur

3

posthypnotic 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

4

dissociation

a split in the consciousness, which allows some thoughts and behaviors to occur simultaneously with others

5

circadian rhythm

the biological clock; regular bodily rhythms that occur on a 24-hour sleep cycle (ie: of temperature and wakefulness)

6

REM sleep

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

7

alpha waves

the relatively slow brain waves of a relaxed, awake state

8

sleep

periodic, natural loss of consciousness - as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation

9

hallucinations

false sensory experiences, such as seeing something in the absence of an external visual stimulus

10

delta waves

the large, slow brain waves associated with deep sleep

11

NREM sleep

non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep

12

suprachiasmatic nucleus (SCN)

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

13

insomnia

recurring problems in falling or staying asleep

14

narcolepsy

a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times

15

sleep apnea

a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings

16

night terrors

a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terrors occur during NREM-3 sleep, within two or three hours of falling asleep, and are seldom remembered

17

dream

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

18

manifest content

according to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content)

19

latent content

according to Freud, the underlying meaning of a dream (as distinct from its manifest content)

20

REM rebound

the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakenings during REM sleep)

21

substance use disorder

continued substance craving and use despite significant life disruption and/or physical risk

22

psychoactive drug

a chemical substance that alters perceptions and moods

23

tolerance

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 effect

24

addiction

compulsive craving of drugs or certain behaviors despite known adverse consequences

25

withdrawal

the discomfort and distress that follow discontinuing an addictive drug or behavior

26

depressants

drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions

27

what is alcohol use disorder also known as

alcoholism

28

alcohol use disorder

alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use

29

barbiturates

drugs that depress central nervous system activity, reducing anxiety but impairing memory and judgment

30

opiates

opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety
