Abstract

When patients with epilepsy cannot be helped with medication, they stay one week in an epilepsy monitoring unit in order to localise the part of the brain that is causing the seizures. The electroencephalogram (EEG) is then recorded over several days as it is the direct measurement of electrical brain activity. We developed a method to extract localising information out of the EEG, even at low signal-to-noise ratios or when the ictal EEGs are severely contaminated. In this survey-paper, we write a manual how to apply the method and illustrate it.
