Chapter 5 narcolepsy, a serious sleep disorder in which those who suffer from it often fall asleep uncontrollably during their everyday routine. Consciousness is the awareness of internal and external stimuli. Recognizing that consciousness is in constant flux, william james (1902) long ago named this flow the stream of consciousness. Mind wandering refers to people"s e(cid:454)perie(cid:374)(cid:272)e of task-unrelated thoughts, In addition to an eeg, the other two crucial devices are an electromyograph (emg), which records muscular activity and tension, and an electrooculograph (eog), which records eye movements. Biological rhythms are periodic fluctuations in physiological functioning. Circadian rhythms are the 24-hour biological cycles found in humans and many other species.

The ascending reticular activating system (aras) consists of the afferent fibres running through the reticular formation that influence physiological arousal.
