Optimization of Granger causation method parameters for the study of limbic epilepsy

Purpose. The aim is to reveal the dependence of Granger causality results on chosen time scales of constructed empirical models in application to the task of investigation of evolution of coupling between brain areas during limbic seizures.

METHOD FOR DETECTING OF TWO TYPES OF BRAIN NEURAL ENSEMBLE ACTIVITY DURING SLEEP ACCORDING TO ELECTROENCEPHALOGRAPHIC RECORDS

Method for detecting of two different types of sleep spindles on electroencephalogram was offered. High precision of this method was demonstrated; it can be used in neurophysiological research of regularity of appearing of different patterns on electroencephalogram.

OPTIMIZATION OF BASIS FUNCTION SET FOR MODEL MAP RECONSTRUCTION OF SHORT ELECTROENCEPHALOGRAM TRACINGS DURING EPILEPTIC SEIZURE

The problem of compact mathematical model reconstruction of short electroencephalogram tracings during epileptic seizure is solved. This kind of model map can be useful in many applications, for example, in time series segmentation with following clustering of obtained fragments. Optimization methods are proposed as a solution. It is shown that application of optimization methods allows to obtain adequate model at that time decreasing number of modeling map basis functions.
