The term vertical occipital fasciculus refers to one of the long association bundles of the cerebral white matter that connects the fusiform gyrus of the temporal lobe with the posterior part of the parietal lobe. It is not readily distinguished in myelin-stained cross-sections ( Crosby-1962 ). Readily revealed by diffusion-weighted imaging and tractography, it is believed to provide a basis for communication between ventral stream regions involved in form perception and dorsal stream regions involved in eye movements and attention" ( Yeatman-2014 ).
