In the last 20 years a lot of works in literature analysed and proposed several methods capable to predict the occurrence of seizures from the electroencephalogram (EEG) of epilepsy patients. In spite of promising results presented, more recent evaluations could not reproduce these optimistic findings. This evaluation poses again the issue of the EEG of epileptic patients used for the prediction of seizures used in a joint way with other data (e.g. fMRI). Spatio- and spectro-temporal brain data (STBD) are the most commonly collected data for measuring brain response to external stimuli or to internal events such as epileptic seizures. Spiking neural networks (SNN) are brain-like connectionist methods, where the output activation function is represented as a train of spikes and not as a potential. This and other reasons do SNN models more biologically close to brain principles than any of the previous Artificial Neural Networks (ANN) methods, and for this reason, are presented as the third generation of ANN. In fact, they have great potential for solving complicated time-dependent pattern recognition problems defined by time series and STBD because of their inherent dynamical representation. Nevertheless several challenges have been reported in works in literature for SNN techniques studied. In this presentation we want to present a particular type of SNN, the evolving SNN (eSNN) with a Quantum inspired evolutionary technique for its weights, parameters and features optimization. In fact, the first challenge approached in in this presentation is the feature and parameter optimization in a SNN. A QiEA is a novel type of quantum-inspired evolutionary algorithm (QiEA) for feature and parameter optimization used here in a SNN. The QiEA is inspired by the multiple universes principle of quantum computing, such as a quantum bit and superposition of states. QiEA represents the most recent advance in the field of evolutionary computation thus, as second objective, the architecture of a QiESNN is presented here and proposed for pattern recognition on temporal brain data. The third objective is about the presentation of a framework where Chaotic measurement and the QiESNN presented before are used in an integrated way for better understanding the epileptic brain. This framework concept, architecture and applications are approached with several possible future evolutions.
