Paper Abstract

Wavelet transforms are used to analyze electroencephalographic (EEG) data recorded from individual subdural electrodes (one dimension) and electrode grids (two dimensions) in direct contact with the brain. Structure in the data is resolved and noise filtered using surrogate data techniques. Spike and seizure detection from individual electrodes are compared with event extraction using windowed Fourier transforms. Wavelet transforms are a powerful means to identify epileptiform activity such as spikes in one dimension from such data, and offer a method to localize the foci of epileptic seizures in two dimensions.
