Clinical SignificanceĮEG waveforms may be characterized based on their location, amplitude, frequency, morphology, continuity (rhythmic, intermittent or continuous), synchrony, symmetry, and reactivity. Even before one starts the analysis, you need to have information regarding several confounding variables including patient's age, state of consciousness, physical and mental activity and the presence of different biological, environmental stimuli and pharmacological agents which can affect the waveforms. It is extremely important to follow a systematic approach while interpreting the waveforms in an EEG recording. The normal EEG is extremely diverse and has a broad range of physiological variability. Analyzing and interpreting the EEG is both an art and science.

Outline normal EEG waveforms, and explain the role of the interprofessional team in providing care of patients who are evaluated by EEG.ĮEG activity reflects the temporal summation of the synchronous activity of millions of cortical neurons that are spatially aligned.

Explain how EEG waveforms are characterized.
