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]
Diagram of gyri of brain viewed on lateral hemisphere. Occipital gyri shown lower right Animation. Occipital lobe (red) of left cerebral hemisphere. The two occipital lobes are the smallest of four paired lobes in the human brain. Located in the rearmost portion of the skull, the occipital lobes are part of the posterior cerebrum.
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.
In larger mammals, including humans, the surface of the cerebral cortex folds to create gyri (ridges) and sulci (furrows) which increase the surface area. [3] The cerebral cortex is generally classified into four lobes: the frontal, parietal, occipital and temporal lobes. The lobes are classified based on their overlying neurocranial bones. [4]
Gray's FIG. 726 – Lateral surface of left cerebral hemisphere, viewed from the side Gray's Fig. 727 – Medial surface of left cerebral hemisphere. In neuroanatomy, a gyrus (pl.: gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg.: sulcus). [1]
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.
Brodmann area 19, or BA 19, is part of the occipital lobe cortex in the human brain.Along with area 18, it comprises the extrastriate (or peristriate) cortex. In humans with normal sight, extrastriate cortex is a visual association area, with feature-extracting, shape recognition, attentional, and multimodal integrating functions.
