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.
Radial glial cells, whose fibers serve as a scaffolding for migrating cells and a means of radial communication mediated by calcium dynamic activity, [21] [22] act as the main excitatory neuronal stem cell of the cerebral cortex [23] [24] or translocate to the cortical plate and differentiate either into astrocytes or neurons.

The mammalian cerebral cortex, the grey matter encapsulating the white matter, is composed of layers. The human cortex is between 2 and 3 mm thick. [11] The number of layers is the same in most mammals, but varies throughout the cortex. 6 layers can be recognized in the neocortex, although many regions lack one or more layers.
Cortical patterning is a field of developmental neuroscience which aims to determine how the various functional areas of the cerebral cortex are generated, what size and shape they will be, and how their spatial pattern across the surface of the cortex is specified. Early brain lesion studies indicated that different parts of the cortex served ...
The outer part of the cerebrum is the cerebral cortex, made up of grey matter arranged in layers. It is 2 to 4 millimetres (0.079 to 0.157 in) thick, and deeply folded to give a convoluted appearance. [21] Beneath the cortex is the cerebral white matter. The largest part of the cerebral cortex is the neocortex, which has
To better understand how exercise affects brain health and helps reduce cognitive decline, we spoke with Marat Reyzelman, M.D., a specialist in neurology and clinical neurophysiology at Wellstar ...
Neurons formed in the ventricular zone migrate to their final locations in one of the six layers of the cortex. [1] The process occurs from embryonic day 10 to 17 in mice and between gestational weeks seven to 18 in humans. [2] The cortex is the outermost layer of the brain and consists primarily of gray matter, or neuronal cell
The Protomap is a primordial molecular map of the functional areas of the mammalian cerebral cortex during early embryonic development, at a stage when neural stem cells are still the dominant cell type. [1] The protomap is a feature of the ventricular zone, which contains the principal cortical progenitor cells, known as radial glial cells.
