Originální abstrakt

In functional magnetic resonance imaging (fMRI), detection of activation is often realized using the general linear model (GLM). The measured signal is modeled using convolution of stimulus time-course and hemodynamic response function (HRF). Both accurate knowledge of experimental stimulus time-course and accurate knowledge of HRF are necessary to obtain valid and meaningful results. The aim of this work is to find how much the results depend on inaccurate knowledge of stimulus time-course
