Anatomical terms of neuroanatomy [edit on Wikidata] |
About 5 centimetres (2.0 in) in front of the occipital pole of the human brain, on the infero-lateral border is an indentation or notch, named the preoccipital notch. It is considered a landmark because the occipital lobe is located just behind the line that connects that notch with the parietoccipital sulcus.
