slide5
Any regular biological rhythm, such as body temperature and sleep-wakefulness, that follows a 24-hour cycle.

circadian rhythm

The sleep stage in which the brain and eyes are active, the muscles are relaxed, and vivid dreaming occurs; also known as paradoxical sleep.

hidden observer

slide22

Chemical substances that alter mood and perception. They work by affecting or mimicking the activity of neurotransmitters. (Includes stimulants, depressants, and hallucinogens.)

psychoactive drugs

slide23

The diminishing of a psychoactive drug’s effect that occurs with repeated use and the need for progressively larger doses in order to produce the same effect.

tolerance

slide25
A physiological need for a drug that is indicated by the presence of withdrawal symptoms when the drug is not taken.

physical dependence

slide27
Psychoactive drugs, such as alcohol, opiates, and barbiturates, that reduce neural activity and slow body functions.

depressants

slide28
Psychoactive drugs, such as caffeine, nicotine, amphetamines, and cocaine, that excite neural activity and speed up body functions.

stimulants

slide29
Psychoactive drugs, such as LSD and marijuana, that distort perception and evoke sensory imagery in the absence of sensory input.

hallucinogens

slide31
Depressants derived from the opium poppy, such as opium, morphine, and heroin; they reduce neural activity and relieve pain.

opiates
