Originální abstrakt

This work deals with the joint EEG-fMRI analysis based on the heuristic model. There is described principle of the heuristic model which assumes that the BOLD (blood oxygen level depend) signal measured by fMRI (functional magnetic resonance imaging) is directly proportional to the spectral shift in the EEG signal. The paper describes algorithm of calculations which was implemented and tested on real data from 22 subjects. The study also monitors effect of different EEG information selection from electrodes of interest (averaging or principal component analysis).

Český abstrakt

Tato práce se zabývá společnou EEG-fMRI analýzou založenou na heuristickém modelu. Je zde popsán princip heuristického modelu, který předpokládá, že BOLD (míra okysličenosti krve) signál, měřený pomocí fMRI (funkční magnetické rezonance) je přímo úměrný spektrálnímu posunu v EEG signálu. Článek popisuje algoritmus výpočtu, který byl realizován a testován na reálných datech 22 subjektů. Studie také sleduje vliv rozdílného výběru užitečné informace z elektrod zájmu EEG (průměrování nebo analýza hlavních komponent).
