Investigation of epileptic structure properties by transfer function.
The paper deals with the possibility of applying linear control theory and the theory of statistical dynamics to the complex and quantitative analysis of electroencephalographic records. The aim is to specify signals in the brain environment, in particular sources, speed and direction of signals, and the determination from results gained of the model of signal transfer, The possibilities of applying Fourier analysis and correlation analysis are examined. The methodical approach of the transient analysis is suggested. Conditions are discussed for approximate application of linear theory. Experimental results, as well as the calculation of transfer parameters of signals are evaluated. The method of magnetic EEG records, the scanning and processing of data on analogue and digital computers are introduced. The method described of correlation and transient analysis arises from the necessity to detect epileptic structures from an evaluation of SEEG records of the deep brain structure.
