I merged precentral gyrus with this article and redirected that page here. If anyone has any comments, please let me know. Semiconscious ( talk  · home) 09:51, 17 August 2005 (UTC)

Subdivisions of Primary Motor Cortex
While reading a paper on Betz cells, stumbled upon such lines:

"..and Brodmann’s original delineation of the primary motor cortex has been revised by other investigators, who described an intermediate precentral area, an area precentralis A, area FA� (von Economo and Koskinas, 1925), area 42 (Vogt and Vogt, 1926), area 4� (agranular, containing the Betz cells), area 4a (agranular, devoid of Betz cells), and area 4s (agranular, without Betz cells, but containing large cells in superior part of layer IV (von Bonin, 1949)), and a frontal ganglionic core, all of which are to some extent part of the original description of Brodmann’s area 4. More recent studies have shown that the primary motor cortex can be divided into two different subareas, 4a (anterior) and 4p (posterior), which differ by their cytoarchitecture and distribution of various neurotransmitter binding sites (Geyer et al., 1996)."

Maybe these subdivisions could be included in the article? --CopperKettle 08:09, 26 February 2007 (UTC)

Please update with: "A census of cell types in the brain’s motor cortex"
I think it would be good to add info from these studies to the article / revise the article's content using it. It's currently featured in 2021 in science like so:

With 17 studies a consortium of researchers concludes the first phase of a long-term project to generate an atlas of the entire mouse (mammalian) brain, releasing an atlas and census of cell types in the primary motor cortex.

There are also CC BY images that could be added to the article.

I think it should at least be mentioned with a text like the above and that it would be best results from the study were instead neatly integrated into the article.
