Prime-like structures in EEG signal matrices: A framework for analysing EEG signals in epilepsy

Epilepsy is a neurological condition affecting millions worldwide.  It is characterised by recurrent seizures.  Electroencephalography remains one of the important investigations into the diagnosis and management of epilepsy, imaging electrical activities of the brain to outline patterns that precede seizures.  Mathematical modeling of seizure patterns requires identifying specific antecedent features of seizures in EEG recordings.  Better understanding of such patterns could contribute to better management and improvement in the quality of life for persons living with
