Spatial Interaction Image of Electroencephalography Signal during Epileptic Seizure on Flat Electroencephalography

Abstract

Electroencephalogram (EEG) is widely used for recording the brain electrical activity. It plays an important role in the detection and classification of epilepsy seizures. In addition, it is believed to possess the ability to detect the location of epileptic focus to some degree. In this study, an EEG data during seizure obtained is analysed and transformed into an image form, namely Flat EEG (fEEG). The fEEG is a method for mapping high dimensional signal into a low dimensional space. The EEG of the obtained signal is clustered and the interactions of the cluster centers are studied and presented in this study.
