In most previous laminar fMRI studies, cortical layers are defined based on an anatomical image that is collected by a different acquisition technique and exhibits different geometric distortion compared to the functional images. We introduce to generate a magnetization transfer (MT) weighted anatomical reference, using identical acquisition design as fMRI measurement. Cortical surface and depth can be reconstructed directly from this MT-weighted anatomical EPI image and all laminar analysis can be performed in the native fMRI image space without the need for distortion correction and registration.
