About 5 centimetres (2.0 in) in front of the [[occipital lobe]] 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 [[parietooccipital sulcus]]. {{ ::occipitallobe.jpg?300|}}
