Basic neurophysiology and the cortical basis of EEG

Abstract

Clinical neurophysiological studies are based on the recording of both spontaneous electrical activity, as with the EEG, or with stimulated responses, such as evoked potentials. The electrical signaling within these neuronal circuits is responsible for both the spontaneous and evoked electrical activity that is routinely measured in the clinical neurophysiology laboratory. This chapter will review some of the basic concepts of neuronal signaling that are important to the understanding of clinical neurophysiology. © 2007 Humana Press Inc.
