Diagram of gyri of brain viewed on lateral hemisphere. Occipital gyri shown lower right. The border between the occipital lobe and the parietal and temporal lobes is characterized by different gyri: the superior occipital gyrus (also known as gyrus occipitalis superior), middle occipital gyrus (or gyrus occipitalis medius), inferior occipital gyrus (or gyrus occipitalis inferior), and ...
The occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The name derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. [1]

The fusiform gyrus, also known as the lateral occipitotemporal gyrus, [1] [2] is part of the temporal lobe and occipital lobe in Brodmann area 37. [3] The fusiform gyrus is located between the lingual gyrus and parahippocampal gyrus above, and the inferior temporal gyrus below. [4]
The lingual gyrus is a structure in the visual cortex that plays an important role in the identification and recognition of words. [12] Studies have implicated the lingual gyrus as being involved in modulating visual stimuli (especially letters) but not whether or not the stimulus was a word. Further, the gyrus is related to the naming of stimuli.
The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 cm in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure ...
In the human it is located in parts of the cuneus, the lingual gyrus and the lateral occipital gyrus (H) of the occipital lobe. It is bounded on one side by the Brodmann area 17 , from which it is distinguished by absence of a band of Gennari , and on the other by the peristriate area 19 (Brodmann-1909).
Here, it is joined at an acute angle by the medial part of the parieto-occipital sulcus. [1] The anterior part of this sulcus gives rise to the prominence of the calcar avis in the posterior cornu of the lateral ventricle. The cuneus is above the calcarine sulcus, while the lingual gyrus is below it. [2] [3]
