Abstract
Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG is derived from a summation of postsynaptic potentials in the apical dendrites of the pyramidal neurons of the cerebral cortex. While modern neuroimaging techniques are capable of disclosing subtle brain lesions, EEG is still an important tool for examining measures of consciousness, the sleep cycle, the effects of hypoxia on the human brain, and epileptic activity. In this chapter, we describe basic and general information about EEG, the clinical usefulness of EEG, and characteristic EEG readings. We also briefly review how anesthetic agents affect EEG readings.
