At the beginning of the seizure (20–40 s) the occurrence of epileptic spikes re-
sulted in a low value of D

; in time-frequency energy distribution it was reected
by very broad-band structures of short duration. During the period of chaotic behav-
ior (60–80 s) characterized by atness of the plot we can see random distribution
of time-frequency structures. Interesting is the period (150–170s) when the system
tends toward limit ...
