Learning EEG
An interactive, modular course for learning how to read electroencephalograms (EEG).
EEG Terminology and Waveforms - Learning EEG
Recognizing the frequency of the waveforms is fundamental to interpreting EEG. Frequency describes how many waves there are per second, and is measured in hertz (Hz). There are four main frequencies of the human brain seen on scalp EEG, in …
normal variants - Learning EEG
A big part of learning EEG is recognizing what is normal from abnormal, especially benign variants that may at first glance appear concerning.
The Normal Awake EEG - Learning EEG
The normal awake EEG should show good organization with variability, reactivity, continuity, and a good posterior dominant rhythm (PDR).
EEG Montages and Technical Components - Learning EEG
Here we'll review the placement of each individual electrode, how to connect them into various montages, and how to get started reading EEG from a technical standpoint.
basic electrophysiology - Learning EEG
Learning eeg. This site is meant for neurology residents, epilepsy or clinical neurophysiology fellows, and EEG technicians. Please reach out with questions, concerns or suggestions; we're always working to improve our content.
the pediatric eeg - Learning EEG
pediatric syndromic eeg patterns. From infancy into adulthood, there are a number of classic EEG patterns and syndromes that you should be familiar with, because each has different treatment requirements and prognosis. Here we'll give a brief overview on the more common ones that have a particular EEG signature. Ohtahara syndrome (EIEE)
The Normal Asleep EEG - Learning EEG
The asleep EEG goes through four phases: stage I, stage II, slow wave, and rapid eye movement (REM). Each phase has characteristic EEG findings.
seizures - Learning EEG
Seizures are an abnormal, synchronous firing of neurons. They can vary in appearance on EEG, but must evolve temporally or spatially.
Epileptiform Activity on EEG - Learning EEG
Epileptiform activity on EEG is indicative of cortical hyperexcitability, which carries an increased risk for seizures and the presence of an epileptic network within the brain. There are several types of epileptiform activity, including single discharges (sharps and spikes) and rhythmic and/or periodic activity.
