Walsh & Hoyt: Cortical Area V1

In the human, the primary visual cortex is situated along the superior and inferior banks of the calcarine fissure, corresponding to area 17 of Brodmann. This area often is called the striate cortex because of a prominent white band of myelinated fibers known as the stria of Gennari, which forms horizontal connections within the cortex. The striate cortex envelops the posterior pole of the hemisphere, extending laterally about 1.5 cm. Rostrally and medially, V1 extends anteriorly beyond the juncture of the parieto-occipital and calcarine fissures, especially ventrally.
