The cerebral cortex is the outer neural layer of the cerebrum and supports major cognitive and perceptual functions.
The cerebral cortex (also called the cerebral mantle) is the outer layer of neural tissue covering the cerebral hemispheres in humans and other mammals. It is the brain’s largest site of neural integration and is essential for higher functions including attention, perception, awareness, thought, memory, language, and consciousness. The cortex is divided into left and right hemispheres by the longitudinal fissure, and the hemispheres are connected beneath the cortex by the corpus callosum and other commissural fibers. Structurally, the cortex is folded into gyri (ridges) and sulci (grooves), which increase surface area and help organize brain circuitry within the skull. The majority of the cortex is the six-layered neocortex (about 90%), while the remaining portion is allocortex with three or four layers. Neurons are organized both horizontally into layers and vertically into microcircuits such as cortical columns and minicolumns. Functionally, different cortical areas specialize—for example, the motor cortex supports movement, the visual cortex supports sight, and association areas integrate information across domains.
The cerebral cortex is the outer neural layer of the cerebrum and supports major cognitive and perceptual functions.
Cortical folding into gyri and sulci increases surface area and is important for functional organization.
The neocortex is six-layered and dominates the cortex; neurons are organized into layers and vertical columns that underpin specialized cortical processing.
Different cortical regions (motor, sensory, association) have distinct functions, such as movement in motor areas and vision in visual areas.
The cerebral cortex is the outer layer of neural tissue of the cerebral hemispheres that enables major functions such as perception, thought, memory, language, and consciousness.
The neocortex is the six-layered portion of the cerebral cortex that makes up about 90% of the cortex in mammals.
Allocortex is the smaller part of the cerebral cortex with three or four layers, including regions such as the hippocampus and olfactory cortex.
A gyrus is a ridge or peak on the surface of the cerebral cortex.
A sulcus is a groove or trough on the surface of the cerebral cortex.
A cortical column is a vertical microcircuit spanning cortical layers that supports coordinated processing of information.
