tokens: Our results show that the most affected frequency bands were delta , theta , beta - 2 and gamma - 2 bands during the epileptiform activity and there were marked differences in terms of spectral densities between three investigated episodes ( basal activity , latent period and epileptiform activity ). Our results may help to analyze novel data obtained using similar experimental models and the simple analysis method described here can be used in similar studies to investigate the basic neuronal mechanism of this or other types of experimental epilepsies
