Abstract :
This paper reports the first experiments conducted to display three dimensional (3D) data resulting from the Time-Frequency Representation (TFR) of 3 StereoElectroencephalographic (SEEG) signals, acquired by linear in-depth electrodes. This visualization approach is aimed at facilitating the interpretation of the spatio-temporal patterns and the relations observed in epilepsy, both during ictal and interictal episodes
