The cerebral cortex, also known as the cerebral mantle, [1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals.It is the largest site of neural integration in the central nervous system, [2] and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
BGP tends to show excessively folded and fused gyri of an abnormally thin cerebral cortex, and an absence of the normal six-layered structure. The abnormally thin cortex is a key factor that distinguishes this form of polymicrogyria from the others, which are characterized by an abnormally thick cortex.
A cortical column is a group of neurons forming a cylindrical structure through the cerebral cortex of the brain perpendicular to the cortical surface. [1] The structure was first identified by Vernon Benjamin Mountcastle in 1957. He later identified minicolumns as the basic units of the neocortex which were arranged into columns. [2]
The human cerebral cortex divided into Brodmann areas on the basis of cytoarchitecture. Cytoarchitecture (from Greek κύτος 'cell' and ἀρχιτεκτονική 'architecture'), also known as cytoarchitectonics, is the study of the cellular composition of the central nervous system's tissues under the microscope.
The Urdu Dictionary Board (Urdu: اردو لغت بورڈ, romanized: Urdu Lughat Board) is an academic and literary institution of Pakistan, administered by National History and Literary Heritage Division of the Ministry of Information & Broadcasting. Its objective is to edit and publish a comprehensive dictionary of the Urdu language.
The cerebral cortex is divided into layers. Each layer is formed by radial glial cells located in the ventricular zone or subventricular zone, and then migrate to their final destination. [8] Layers of the cerebral cortex, oriented from most superficial (top of image) to deepest (bottom of image).
The senses of vision, audition, and touch are served by the primary visual cortex, the primary auditory cortex, and primary somatosensory cortex. The cerebellar cortex is the thin gray surface layer of the cerebellum , consisting of an outer molecular layer or stratum moleculare , a single layer of Purkinje cells (the ganglionic layer), and an ...
Gyrification is the process of forming the characteristic folds of the cerebral cortex. [1] The peak of such a fold is called a gyrus (pl. gyri), and its trough is called a sulcus (pl. sulci). The neurons of the cerebral cortex reside in a thin layer of gray matter, only 2–4 mm thick, at the surface of the brain. [2]
