2023年10月30日 · A gyrus (plural: gyri) is a ridge on the surface of the brain. Each ridge is surrounded by fissures known as sulci (singular: sulcus). Gyri are unique structures that have an important evolutionary function; they increase the surface area of the brain up to an impressive 2000 centimeters squared.

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 .

2023年5月9日 · Gyrus Functions. Each type of gyrus has a specific function that contributes to the overall functioning of the brain. Here is an overview of the functions of different types of gyrus: Precentral Gyrus Function. The precentral gyrus is responsible for …

2023年10月30日 · On its surface, the frontal lobe contains four principal gyri: the precentral, superior frontal, middle frontal, and the inferior frontal gyrus. The functions of the frontal lobe are numerous. It is associated with higher cognitive functions, such as decision making, motivation, problem-solving, planning and attention.

2023年9月19日 · Gyri (gyrus): These are the raised, convex ridges on the surface of the cerebral cortex. They increase the surface area of the cortex, allowing for greater cognitive processing. Prominent gyri, like the precentral gyrus, are associated with …

颞中回（英語： Middle temporal gyrus ）是大脑 颞叶的一个脑回，位于颞下沟与颞上沟之间 [1] [2] 。 结构上， 外侧沟 与 枕前切迹 之间可划出一条虚拟连线，被视为颞中回的后部界限。

2024年9月30日 · Gyri are the raised ridges on the surface of the cerebral cortex, the outermost layer of the brain. They’re like the mountains in a landscape of neural activity, working in tandem with their valley-like counterparts, the sulci.

2023年10月30日 · The cingulate gyrus is a part of the human brain on the medial aspect of each of the cerebral hemispheres. Along with the parahippocampal gyrus, it makes up the limbic cortex of the brain’s limbic system .

2023年7月24日 · The precentral gyrus is the anatomical location of the primary motor cortex, which is responsible for controlling voluntary motor movement on the body's contralateral side. The primary motor cortex is topographically organized and creates a somatotropic map. Texts often refer to this map as the motor homunculus, or “little man.”

There is considerable interest in the structural and functional properties of the angular gyrus (AG). Located in the posterior part of the inferior parietal lobule, the AG has been shown in numerous meta-analysis reviews to be consistently activated in a variety of tasks. This review discusses the i …
