Slice selection and functional domains in human visual cortex. a depicts the optimal region of flat gray matter in primary visual cortex (parallel to the calcarine sulcus) in one subject from which columnar level fMRI maps of ODC (b) and orientation preference (c) are generated and characterized. The functional maps in b and c are zoomed views of the ROI in a. The red and blue colors in b indicate preferences to right or left eye stimulation, whereas the color distribution in c represents a given voxel's fMRI time course phase, which is indicative of its preferred stimulus orientation.
