[Use of the indicators of spectral power of cortical biopotentials for evaluation of the processes of generalization of epileptic activity].
Spatial density of spectral power of bioelectric cortical activity was analyzed in patients with primary-generalized (PG) and secondary-generalized (SG) epilepsy within a range of 0.5-30 Hz divided by 22 narrow bands. The range 0.5-7.0 Hz was shown to play a special role in epileptic activity generalization. The PG forms and SG epilepsy with a focus in the left hemisphere are characterized by the predominance of spatial density of spectral power in some bands of the low-frequency range in the cortical structures of the left hemisphere. On the contrary, SG epilepsy with a focus in the right hemisphere is marked by the same features in the cortical structures of the right hemisphere.
