cerebral cortex
Let an agent explain the cerebral cortex, relay anatomy, layers, functional areas, lateralisation and research from neuroscience sources, route stroke signs to emergency services, describe the named regions and model species, and distinguish the cortex from subcortical structures, white matter, the cerebellum and popular myths such as left brain and right brain personalities.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the cerebral cortex, relay anatomy, layers, functional areas, lateralisation and research from neuroscience sources, route stroke signs to emergency services, describe the named regions and model species, and distinguish the cortex from subcortical structures, white matter, the cerebellum and popular myths such as left brain and right brain personalities.
The outer layer of grey matter of the cerebrum, about 2 to 4 millimetres thick in humans, folded into gyri and sulci and organised mostly as six-layered neocortex, divided into frontal, parietal, temporal and occipital lobes and into functional areas such as the primary motor, primary somatosensory, visual and auditory cortices, with left and right hemispheres showing some lateralisation, for example of language in most people; research also uses animal models such as the mouse cortex, whose organisation differs in scale and detail from the human cortex. Sudden weakness, speech loss or facial droop may be a stroke affecting the cortex and needs emergency services.
What it is for: Perception, movement, language and thought.
It can be explain anatomy and layers; relay functional areas; describe lateralisation and myths; route stroke emergencies.
Distinguishing features
Folded surface
Layered organisation
Functional maps
Hemispheric lateralisation
What it looks like
The wrinkled outer surface of the brain with ridges and grooves.
Physical character
thickness: about 2-4 mm - human
neocortex layers: 6 count
Brodmann areas: 52 count - Brodmann 1909
How it is recognised
Outer grey matter of the cerebrum
Human cerebral cortex, mouse cortex, primary somatosensory cortex, right cerebral cortex, left cerebral cortex, sensory cortex
Subcortical nuclei lie deeper; white matter contains axons; the cerebellum is a separate structure; left-right personality types are myths
