Cerebral cortex - Wikipedia
Layer III, the external pyramidal layer, contains predominantly small and medium-size pyramidal neurons, as well as non-pyramidal neurons with vertically oriented intracortical axons; layers I through III are the main target of commissural corticocortical afferents, and layer III is the principal source of corticocortical efferents.

Cerebral cortex: Structure and functions - Kenhub
2023年10月30日 · The cerebral cortex (cortex of the brain) is the outer grey matter layer that completely covers the surface of the two cerebral hemispheres. It is about 2 to 4 mm thick and contains an aggregation of nerve cell bodies. This layer is thrown into complex folds, with elevations called gyri and grooves known as sulci.

The Cerebral Cortex - ScienceDirect
2017年1月1日 · The human cerebral cortex consists of a 2–5-mm-thick layer of gray matter containing 10–14 billion neurons that, for most of its surface, is stratified in six layers. The six-layer cortex is described as “neocortex” to distinguish it from a much less extensive region of cortex having fewer layers (allocortex).
Hierarchical organization of cortical and thalamic connectivity
