Alpha wave
A waveform of 9 to 12 cycles per second recorded by electroencephalogram that usually indicated relaxed waking
Beta wave
A waveform of 15 to 30 cycles per second recorded by an electroencephalogram that usually indicated alert waking
Circadian rhythm
A daily biological rhythm
Consciousness
A state of awareness
Delta wave
A waveform of 1 to 4 cycles per second recorded by electroencephalogram that usually indicated deep non-rapid eye movement sleep
Gamma wave
A waveform of more than 30 cycles per second recorded by electroencephalogram that indicated attention to sensory input
Hallucinogen
A drug that stimulates the experience of false perceptions
Meditation
A voluntary alteration of consciousness characterized by positive emotion and as sense of thought
Narcolepsy
A sleep disorder characterized by the intrusion of rapid eye movement phenomena into waking.

Psychoactive drug
Any drug with the capability of altering a person’s state of consciousness
Rapid eye movement (REM) sleep
The component of sleep characterized by waveforms resembling waking, as measured by electroencephalogram, accompanied by rapid motion of the eyes, muscular paralysis, and sympathetic nervous system activation.
