In neuroanatomy, a sulcus (Latin: "furrow"; pl.: sulci) is a shallow depression or groove in the cerebral cortex. One or more sulci surround a gyrus (pl. gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals. The larger sulci are also called fissures.
Specifically, different patterns appear in the superior frontal sulcus, Sylvian fissure, inferior frontal gyrus, superior temporal gyrus, and olfactory sulci. [45] These areas relate to working memory, emotional processing, language, and eye gaze, [ 46 ] and their difference in location and level of gyrification when compared to a non-autistic ...
Differences between genders regarding the average width of the central sulcus as one ages has also been shown. [10] The average width of the central sulcus in males tends to increase more rapidly over time than that of females. [10] The surface area of the central sulcus has proven to have an effect on the handedness of an individual. [11]
In the human brain, the superior temporal sulcus (STS) is the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe of the brain.A sulcus (plural sulci) is a deep groove that curves into the largest part of the brain, the cerebrum, and a gyrus (plural gyri) is a ridge that curves outward of the cerebrum.
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 . Structure
The predetermined language-calculation network was limited to the left inferior frontal gyrus, angular gyrus, superior parietal lobule, and the horizontal portion of the intraparietal sulcus. The results were significant to support that there was a pattern of left lateralization for each of these tasks all activating the Perisylvian fissure ...
The superior temporal gyrus (STG [1]) is one of three (sometimes two) gyri in the temporal lobe of the human brain, which is located laterally to the head, situated somewhat above the external ear. The superior temporal gyrus is bounded by: the lateral sulcus above; the superior temporal sulcus (not always present or visible) below;
Brodmann area 45 (BA45), is part of the frontal cortex in the human brain.It is situated on the lateral surface, inferior to BA9 and adjacent to BA46.. This area in humans occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of the lateral sulcus (H), a portion of the orbital part of the inferior frontal gyrus (H).
