Anatomical terminology

In human neuroanatomy, the longitudinal striae (also "striae lancisi" or "nerves of Lancisi") are two bundles of fibres of the supracallossal gyrus running along the corpus callosum of the brain. They were originally described by Italian physician, epidemiologist and anatomist Giovanni Maria Lancisi.[1] The striae are categorized as medial longitudinal stria and lateral longitudinal stria; the area between the striae are a useful neurosurgical mark of the middle of the corpus callosum.
