Abstract
The reconstruction of efficient models from experimental time series often requires special approaches. The coupling between rat intracranial electroencephalogram channels (as models of absence epilepsy) is analyzed using improved predictive models by means of nonlinear Granger causality. The calculations have shown the coupling growth 1.5-2 seconds before an epileptic seizure. The scenario of coupling level changes during the seizure is not the same for different electroencephalogram channels.
