| Abstract | The technique of functional magnetic resonance imaging (FMRI) allows the measurement of functional cerebral blood flow changes occurring with specific tasks. However, the spatial relationship between neuronal activity and functional cerebral blood flow changes is not known yet. This study compares the centre of neuronal activation (measuired by magnetoencephalography) with that of the blood flow response (measured by FMRI) to unilateral motor stimulationin eight subjects. The results show a mean localization difference of 1.6 cm and demand application of methodological improvements as recently suggested. | |
