We provide direct evidence of columnar organization of direction selective features (DSF) in human area MT using spin echo BOLD based fMRI at ultra high fields (7 tesla). We demonstrate that the functional selectivity and sensitivity of high field high resolution SE BOLD fMRI is sufficient to resolve the fine grained organization of feature representations within higher level folded cortical areas.
