Approximately 1% of the world's population suffer from epileptic seizures throughout their lives that mostly come
without sign or warning. Thus, epilepsy is the most common chronical disorder of the neurological system. In the
past decades, the problem of detecting a pre-seizure state in epilepsy using EEG signals has been addressed in
many contributions by various authors over the past two decades. Up to now, the goal of identifying an impending
epileptic seizure with sufficient specificity and reliability has not yet been achieved. Cellular Nonlinear Networks
(CNN) are characterized by local couplings of dynamical systems of comparably low complexity. Thus, they
are well suited for an implementation as highly parallel analogue processors. Programmable sensor-processor
realizations of CNN combine high computational power comparable to tera ops of digital processors with low
power consumption. An algorithm allowing an automated and reliable detection of epileptic seizure precursors
would be a"huge step" towards the vision of an implantable seizure warning device that could provide information
to patients and for a time/event specific treatment directly in the brain. Recent contributions have shown that
modeling of brain electrical activity by solutions of Reaction-Diffusion-CNN as well as the application of a CNN
predictor taking into account values of neighboring electrodes may contribute to the realization of a seizure
warning device.
In this paper, a CNN based predictor corresponding to a spatio-temporal filter is applied to multi channel
EEG data in order to identify mutual couplings for different channels which lead to a enhanced prediction
quality. Long term EEG recordings of different patients are considered. Results calculated for these recordings
with inter-ictal phases as well as phases with seizures will be discussed in detail.
