Quantitative EEG - An Introduction

Quantitative Electroencephalography (qEEG) is the digital analysis of the raw EEG data with the application of mathematical and analytical techniques to characterize the EEG signal.

Basics of EEG

20 minutes of artifact-free recording of epileptiform activity that consists of synchronized depolarization and repolarization of thalamic and cortical neurons. 20-electrode placement system along with bipolar and referential montages allows comparison of epileptiform activity on both sides of the brain as well as localization of seizure. Many provocative techniques such as hyperventilation, intermittent photic stimulation, and sleep are used to produce epileptiform waves.
