Original Abstract

The aim of this paper is to describe and mutually compare the commonly used methods for evaluating functional brain connectivity, i.e. correlation analysis, principal component analysis and independent component analysis, and for effective brain connectivity, i.e. psycho-physiological interaction and dynamic causal modelling. For this purpose, all approaches are performed on the same data set, and the mutual relationships among these methods are pointed to.

Czech abstract

Cílem této práce je popsat a vzájemně porovnat metody běžně používané pro výpočet funkční mozkové konektivity jako je: korelační analýza, analýza hlavních komponent a analýza nezávislých komponent, a method pro výpočet efektivní mozkové konektivity jako je: psycho-fyziologická interakce a dynamické kauzální modelování. Za tímto účel jsou všechny přístupy realizovány na stejném souboru dat a vzájemné vztahy mezi těmito metodami jsou patřičně zdůrazněny.
