EEG‐fMRI of focal epileptic spikes: Analysis with multiple haemodynamic functions and comparison with gadolinium‐enhanced MR angiograms
Explore this paper's citation graph
Summary
Co‐registration of statistical maps with gadolinium‐enhanced MRIs suggested that the detected fMRI responses were not in general related to large veins, and Signal loss in the temporal lobes seemed to be an important factor in 7 of 12 patients who did not show fMRI activations with any of the HRFs.
