4

alpha waves

5

6

hallucinations

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

7

delta waves

9

insomnia

recurring problems in falling or staying asleep

10

narcolepsy

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

11

14

manifest content

18

19

dissociation

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

20

psycho active drug

a chemical substance that alters perceptions and moods

21

tolerance

the diminishing effect with regular use of the same dose of a drug

22

withdrawal

the discomfort and distress that follow discontinuing the use of an addictive drug

23

physical dependence

a physiological need for a drug, marked by unpleasant withdrawal symptoms when the drug is discontinued

24

psychological dependence

a psychological need to use a drug, such as to relieve negative emotions

25

addiction

compulsive drug craving and use, despite adverse consequences

26

depressants

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

27

barbiturates

drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgement

28

opiates

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

29

stimulants

drugs (such as caffeine, and nicotine) that excite neural activity.

30

amphetamines

drugs that stimulate neural activity, causing speeded up body functions and associated energy and mood changes

31

methamphetamine

stimulates the central nervous system, speeds up body functions, associated energy and mood changes

32

ecstasy (MDMA)

a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy.

33

hallucinogens

psychedelic drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input.

34
