What was done
This paper is a narrative review examining the developmental and evolutionary mechanisms that direct cerebral cortical patterning and the emergence of functionally distinct neocortical areas in mice and humans.
What was found
The abstract provides conceptual background rather than numerical data. It reports that virtually all neocortical areas share a six-layered neuronal architecture, similar thickness, and comparable cell density, forming over roughly the same developmental period despite ultimately subserving divergent sensory, motor, and cognitive functions.
Why it matters
Elucidating the developmental mechanisms of cortical area formation helps explain how anatomical and functional complexity evolved to support advanced mammalian behavior.
Limits
The abstract reports no original experimental datasets, sample sizes, or quantitative outcome measures, serving solely as a high-level narrative overview.

- supports The cerebral cortex is approximately 3 millimeters thick, consists of six layers, and operates using canonical circuitry across regions.
