Abstract

This paper discusses the use of a common signal-processing tool, the spectrogram, in the detection and localization of epileptic seizures. Spectrograms are computed from electrocorticograms (ECoG) obtained by measuring electric potentials directly on the surface of the brain. Chirp-like patterns are observed in spectrograms of single-channel ECoG recordings during seizure activity which appear unique for each patient. Detection and localization of epileptic seizures are illustrated through design of a matched filter based on these patterns.
