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 ...
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.
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 ]
Brodmann area 18, or BA18, is part of the occipital cortex in the human brain.It accounts for the bulk of the volume of the occipital lobe. It is known as a "Visual Association Area" or V2 and is a first stage in processing or feature extraction of retinotopic images from V1.
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 ] Gyri and sulci create the folded appearance of the brain in humans and other mammals .
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 collateral fissure is a large sulcus on the tentorial surface of the cerebral hemisphere and extends from near the occipital pole to within a short distance of the temporal pole. It is also known as the medial occipitotemporal 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.
