Histological evidence in humans and non-human primates suggests a functional sub-division of extra-striate visual areas V2/V3, with a patchy or stripe-like pattern of neurons belonging to different information pathways of the visual system. Here, using 3D EPI BOLD at 7T and a dedicated surface coil, we show in vivo evidence of these sub-divisions in humans.
