Jun 28, 2021 · The collateral sulcus, also known as the medial occipitotemporal sulcus, runs anteroposteriorly on the inferior surface of the temporal lobe and occipital lobe. Anteriorly it is sometimes continuous with the rhinal sulcus 1-3 .

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 collateral sulcus can be seen on the lower surface of the cerebrum, near the back of the brain. It stretches forward from near the occipital pole, but doesn’t reach the frontmost part (i.e. the temporal pole). The collateral sulcus turns into the rhinal sulcus as it continues forward.

Mar 30, 2025 · The collateral sulcus, also known as the medial occipitotemporal sulcus, runs in an anteroposterior direction on the inferior surface of the temporal and occipital lobes. Anteriorly, the collateral sulcus can, in some cases, transition into the rhinal sulcus.

The Collateral Sulcus (ColS) is yet another anteroposteriorly running temporal sulcus. It is the most mesial temporal sulcus and provides the lateral limit of the parahippocampal gyrus. The ColS is best seen with the surface rendering tilted halfway between a …

calcarine sulcus and the parieto-occipital sulcus. Inferior to the calcarine sulcus in the tentorial surface of the lobe, there is lingualgyrus. The collateral sulcus separates the lingual gyrus from the fusiform gyrus. Among the transverse sulci, the most frequently cited sulci are the transverse occipitalis and the lateral occipital sulci.

The term collateral sulcus (cos) refers to a cleft on the mesial aspect of the cerebral hemisphere that separates the lingual gyrus (LNG) of the occipital lobe (OLB) from the fusiform gyrus (FUG) of the temporal lobe (TLB) .

The collateral sulcus is in the ventromedial surface of the temporal lobe, and it defines where the outer reaches of the hippocampal complex are located. This region includes entorhinal, perirhinal, and parahippocampal cortical areas.

Collateral sulcus The collateral sulcus was present in all specimens. It ran rostrocaudally from the anterior-medial temporal basal region to the occipital lobe, separating the parahippocam-pal and lingual gyri, medially, from the fusiform gyrus, lat-erally. …

Apr 18, 2014 · The major landmarks are the collateral sulcus (separated into the rhinal, proper, and caudal segments) and occipitotemporal sulcus (often interrupted), which were always present in this study. The bifurcation of the caudal collateral sulcus is a useful landmark.
