Abstract:

By measuring EEG frequencies by Burch method (analysis of periods), determining the exact times of various EEG frequencies, which the specialist sees by visual inspection, we can obtain more precise and certain information regarding the comitial focus than by FFT, as this technique provides wave indexes for each frequency. Frequency analysis by FFT also finds inexistent frequencies on the route, resulted by decomposing in Fourier sequences, and therefore sometimes the result is false. In order to observe the spreading of ample, super-voltage comitial-type discharges on the cerebral cortex, an original technique was implemented, which determines graphically by maps the time measured in milliseconds in which the comitial wave spreads on the cerebral cortex (time mapping).
