An EPI pulse sequence is performed by an NMR system which acquires images of the brain over a time interval during which the subject performs a function or is stimulated in a pattern. The voxel size of acquired images corresponds to the anatomy of cortical microcirculation structures which range from 1 to 2 mm along all three axes. A centric view order is employed and one-half of k-space is sampled to reduce scan time for each image.
