Document Summary

Mind wandering- when people experience task-unrelated thoughts (much like freud"s concept of a slip of the tongue/ freudian slip) Electroencephalograph (eeg)- a device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp. Circadian rhythms- 24-hour biological cycles found in humans and many other species. Slow-wave sleep (sws)- consists of sleep stages 3 and 4, during which high-amplitude, low- frequency delta waves become prominent in eeg recordings. Rem sleep- relatively deep stage of sleep marked by rapid eye movements; high-frequency, low- amplitude brain waves; and vivid dreaming. Non-rem sleep- consists of sleep stages 1 through 4, which are marked by an absence of rapid eye movements, relatively little dreaming, and varied eeg activity. Ascending reticular activating system (aras)- consists of the afferent fibres running through the reticular formation that influence physiological arousal. Narcolepsy- a disease marked by sudden and irresistible onsets of sleep during normal waking.
