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 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 ]
This area is also known as occipitotemporal area 37 (H). It is a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex . It is located primarily in the caudal portions of the fusiform gyrus and inferior temporal gyrus on the mediobasal and lateral surfaces at the caudal extreme of the temporal lobe .
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.
Above the medial, Y-shaped sulcus lies the cuneus, and the area below the sulcus is the lingual gyrus. Damage to the primary visual areas of the occipital lobe can cause partial or complete blindness.
The inferior surface of the temporal lobe is concave, and is continuous posteriorly with the tentorial surface of the occipital lobe. It is traversed by the occipitotemporal sulcus, also known as the lateral occipitotemporal sulcus [2] which extends from near the occipital pole behind, to within a short distance of the temporal pole in front, but is frequently subdivided by bridging gyri.
In the occipital lobe, the lateral occipital sulcus, where present, divides the lateral, or middle occipital gyrus into a superior and an inferior part, which are then continuous in front with the parietal and temporal lobes.
The lingual gyrus is the hypothetical location of V4 in macaque monkeys. In humans, this area is called hV4. The fusiform gyrus is the hypothetical location of V4α, a secondary area for colour processing. More: Colour centre. Visual area V4 is one of the visual areas in the extrastriate visual cortex.
