The ECD height is shown as a percentage ratio of the distance from the calcarine sulcus, and the depth is the ratio from the occipital pole to the total length of the calcarine sulcus, that is from the occipital (O) pole to the parieto-occipital (PO) sulcus.
The caudal point of the calcarine sulcus is defined as the zero point, and the upper side of the calcarine sulcus is assumed to be positive.
The coordinate plane is similar to a coronal section of the MR image, with the longitudinal fissure as the ordinate and the calcarine sulcus as the abscissa.
Occipital lobe (468 words)
The primary visual area is Brodmann area 17, located in the interior portion of the occipital lobe at the calcarine sulcus and sometimes continuing onto the surface of the lobe.
The front edge of the occipital lobe is separated from the parietal lobe by the Parieto-occipital sulcus.
Above the medial, Y-shaped sulcus lies the cuneus, and the area below the sulcus is the lingual gyrus.
