The Normal EEG,. During these years, the EEGs of normal persons have been recorded in numerous situations and under a wide variety of conditions. Tracings have been taken during performance of a virtually endless list of different tasks and activities, as well as during different states of consciousness, from pers

This knowledge can be gained only by going over a large number of EEG tracings and becoming familiar with the various physiological and pathological alterations commonly and uncommonly seen in the EEG.

Average Evoked Potentials,ncy brain-stem auditory-evoked potentials, as well as short- and intermediate-latency cortical-evoked potentials, lately have proved to be valuable clinical tools for objectively testing afferent functions in patients with neurological and sensory disorders. This being the case, there is need for th

To address this problem, a special technique known as seizure monitoring is increasingly being used at many hospitals and epilepsy centers. In some EEG laboratories, seizure monitoring is used routinely with patients suspected of having seizures. Additionally, some laboratories

Clinical Use of Brain Electrical Activity Mapping,techniques is brain electrical activity mapping (BEAM)., defined as the topographic analysis of scalp-recorded EEG or evoked-potential (EP) data (Duffy FH, Burchfiel JL, and Lombroso CT, 1979; Duffy FH, 1986). Technically, topography refers to the analysis of spatial dimensions, whereas topographic

Before considering these data and entering into a discussion of the current ideas concerning the origin of the EEG, it is essential that we look at the neurons — the cellular units of the nervous system. We will examine them from the points of view of anatomical structure and generation of bioelectric activity.
