a: visual cortex ~
b: a crumpled sheet


"Rather than lining the skull, as the retina lines the eye, the visual cortex is like a crumpled sheet stuffed into the skull. Each location where the folded cortex forms a ridge visible from the exterior is called a gyrus, while each shallow furrow that separates a pair of gyri is called a sulcus."
