Elektroencefalografie a audiovizuální stimulace

Abstract

This thesis deals with questions of scanning electric activity of brain,¬ so-called electroencephalograph (undermentioned EEG), methods of audiovisual stimulation (undermentioned AVS) and a data-measurement processing. Theoretical part of the thesis is engaged in a theory of EEG signal creation, history and even in current methods of purchasing and processing of the EEG signal, theory of AVS and a theory of biofeedback. For measuring EEG signal with or without an application of AVS methods has been used EEG diagnostic device by Alien company. Its attributes are described in the thesis as well. For elaboration and analysis has been created a programme aplication EEG_xhroze00.fig which realizes frequency spectrum analysis using Fast Fourier Transform algorithm (FFT) and another programme aplication brain_mapping.fig for mapping activity of brain using designed algorithm.

Tato diplomová práce se zabývá problematikou snímání elektrické aktivity mozku, takzvanou elektroencefalografii (dále jen EEG), metodami audiovizuální stimulace (dále jen AVS) a zpracováním naměřených dat. Teoretická část diplomové práce se zabývá teorií vzniku EEG signálu, historií i současnými metodami pořizování a zpracování EEG záznamu, teorií AVS a teorií biologické zpětné vazby (biofeedback). Pro měření EEG signálů bez aplikace AVS metod, a s aplikací AVS metod, je použit EEG diagnostický přístroj firmy Alien, jehož vlastnosti jsou v práci popsány. Pro zpracování a analýzu signálu je navržena programová aplikace EEG_xhroze00, která realizuje frekvenční spektrální analýzu pomocí algoritmu rychlé Fourierovy transformace FFT, a programová aplikace brain_mapping pro mapování mozkové aktivity (brain mapping) pomocí navrženého algoritmu.
