Electroencephalography (EEG) enables clinicians to
study and analyze electrical fields of brain activity by
recording amplified voltage differences between electrodes placed on the scalp, directly over the cortex (e.g.,
with subdural electrodes), or within the brain (with
depth electrodes). For each electrical field, the clinician
attempts to determine the nature, location, and configuration of the generator of EEG patterns and whether
they are normal or abnormal. The clinical interpretation
of the EEG findings must correspond to the patient’s
symptoms, findings on physical examination, and
results of other investigations, such as brain imaging.
