Knowra Neocortex Neocortex The neocortex is the six-layered part of the mammalian cerebral cortex involved in sensory perception, motor control, and higher cognition. Its layered architecture and specialized areas support complex information processing.
Cortical column : A proposed vertical organization of neurons in the cerebral cortex that respond to related inputs or perform related computations. Columnar organization links neurons across neocortical layers, though its universality and functional meaning remain debated.
Cerebral cortex : The outer layer of the cerebral hemispheres, involved in perception, movement, memory, and cognition. The neocortex is the largest and evolutionarily newest part of the cerebral cortex.
Primary visual cortex : The first cortical region that receives and processes visual signals from the thalamus. This neocortical area illustrates layered processing of sensory input.
Cortical development : The prenatal and postnatal processes that form and refine the cerebral cortex. Neocortical layers arise through precisely timed stages of neuronal production and migration.
Allocortex : Cortical tissue with fewer than six layers, including the hippocampal formation and olfactory cortex. Allocortex contrasts with the neocortex's characteristic six-layer organization.
Pyramidal cell : An excitatory neuron with a pyramid-shaped cell body and branching dendrites, abundant in the cerebral cortex. Pyramidal cells provide much of the neocortex's excitatory signaling and long-range output.
Cerebrum : The largest part of the brain, comprising the cerebral hemispheres and their associated structures. The neocortex forms the outer sheet covering much of the cerebrum.
Primary somatosensory cortex : A cortical region that processes touch, proprioception, and other bodily sensations. Its organized maps show how neocortex represents locations across the body.
Radial glial cell : A neural progenitor cell that generates neurons and guides their migration during brain development. Radial glia help build the neocortex by producing neurons and guiding them toward their layers.
Hippocampus : A medial temporal-lobe structure essential for forming episodic memories and supporting spatial navigation. Its allocortical structure and memory roles differ from neocortical organization and functions.
