Description	Ve funkční magnetické rezonanci (fMRI) využíváme obvykle k detekci aktivace obecného lineárního modelu (GLM). Měený signál je modelován na základě konvoluce impulsní odezvy hemodynamiky (HRF) a časového průběhu experimentální stimulace. Přesná znalost obojího je nutná k získání validních výsledků. Cílem práce je ohodnotit, jak nepřesná znalost časového průběhu stimulace ovlivní výsledky fMRI analýzy využívající GLM. (cs) 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 In functional magnetic resonance imaging (fMRI), detection of activation is often realized using the general linear model (GLM).
