2023年9月19日 · Sulci are grooves that surround each gyrus, with deeper grooves termed fissures. They increase the cerebral cortex’s surface area and create boundaries between brain lobes. Primary sulci form independently before birth, while secondary sulci develop afterward due to other factors. Sulci can be complete (very deep) or incomplete (shallow).

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.

2024年9月30日 · Brain sulci, derived from the Latin word “sulcus” meaning furrow or groove, are the deep folds that characterize the surface of the cerebral cortex. They’re like the Grand Canyons of your cranium, carving out distinct regions and increasing the surface area of the brain.

2019年10月9日 · Gyri (singular: gyrus) are the folds or bumps in the brain and sulci (singular: sulcus) are the indentations or grooves. Folding of the cerebral cortex creates gyri and sulci which separate brain regions and increase the brain's surface area and cognitive ability.

他第一次颠覆了前人脑沟脑回杂乱无章的认识，提出了额颞顶枕脑叶（lobe）的概念，从种系发生描述了各条初级脑沟（primary sulci）和次级脑沟（secondary sulci），以“plis de passage”指代相邻脑回的连接（fold）。

2018年1月7日 · Gyri (singular gyrus) refer to the ridges between two clefts on the cerebral surface of the brain. The clefts that surround a gyrus are called sulci. The surface area of the brain is increased by the presence of gyri. The increased surface area gives a better cognition inside a limited size by the skull.

2024年9月30日 · Brain sulci, labeled meticulously by anatomists, are the grooves or furrows that crisscross the surface of the brain. They’re not just random dents or creases; each sulcus has a specific name, location, and function, working in harmony with its neighboring structures to orchestrate the symphony of human cognition.

In this article we propose a robust voxel-coding methodology to automatically extract and parameterize the sulcal surfaces from volume data sets. We describe sulci as a collection of 2D contours generated from successive data slices. The contours are parameter curves of the sulci.

One of the grooves or furrows on the surface of the brain, bounding the several convolutions or gyri; a fissure. 2. Any long, narrow groove, furrow, or slight depression. 3. A groove or depression in the oral cavity or on the surface of a tooth. 4.

2023年8月1日 · Cerebral sulci are the furrows or depressions that demarcate the highly convoluted external surfaces of the brain hemispheres into a series of folds called gyri. These sulci are the extension of the subarachnoid space. They are referred to as fissures when they are deep and anatomically consistent.
