It represents fluctuating dendritic potentials from superficial cortical layers, which are recorded in an organized array pattern and require voltage amplification to be captured.

It is a tracing of voltage fluctuations versus time recorded from multiple electrodes placed over the scalp in a specific pattern to sample different cortical regions. Review the clinical significance of epileptiform abnormalities noted on EEG recordings.Įlectroencephalography (EEG) was first used in humans by Hans Berger in 1924.Describe non-epileptiform abnormalities noted on EEG recordings.Outline the specific electrographic features of epileptiform abnormalities noted on EEG recordings.Identify various epileptiform abnormalities noted on EEG recordings.This activity reviews the abnormal waveforms in EEG recordings to help review these abnormalities for the clinical provider and improve patient outcomes. The electroencephalographer is expected to have the significant skills to recognize artifacts, and also have a thorough understanding of normal benign variants. In order to identify abnormal waveforms indicative of disease on an EEG, the reader should have a basic understanding of the normal EEG pattern in various physiological states in children and adults. Abnormal waveforms seen on an electroencephalogram (EEG) recording include epileptiform and non-epileptiform abnormalities.
