Visualizing Ripples and Fast Ripples in Scalp and Intracranial EEG

Ripples (80-200 Hz) and Fast Ripples (200-600 Hz) are brief (15-200 msec) bursts of spectral energy that can occur superimposed on inter-ictal or ictal epileptiform spikes or superimposed on the EEG background. Both ripples and fast ripples may delineate regions that are necessary and sufficient for seizures known as the epileptogenic zone and correspond with disease severity. BRAIN QUICK can visualize ripples and fast ripples and distinguish these events from artifact. BRAIN QUICK plug-ins can quantify and automatically annotate each ripple, fast ripple, and spike event for higher-level custom analysis approaches using Python or Matlab.
