Unnecessary footnote
Brief continuation from previous item, much less important than the main point of neglected measurement.
Along with the mismeasure of area, there's a misdescription of the difference between the cortex and the cerebellum, which shows the same neglect and disdain of SKILL.
In the cerebral cortex, regions representing different parts of the body are arranged roughly like they are in the actual body: juxtaposed and orderly. But in the cerebellum, they were placed more randomly.
This could be an oversimplification by the editor, but nevertheless it's not accurate.
On one side, the arrangement in the cortex is not strictly orderly. Unrelated parts are juxtaposed.
Here's the classic 'homunculus' for mapping of sensory regions:
On the other side, the cerebellum IS arranged in an orderly way. It's ordered by SKILL, not by body parts. Each subsection of one folium was set up 'on the fly' by repeated rehearsal and performance of a specific action involving various parts.
The input command arrives from sensory centers in the brainstem via the blue and green paths. The neurons in this folium have been programmed by repetition to perform one specific action for one specific PURPOSE. They run through the action, sending sequential commands toward the spine via the dentate nucleus (brown).
Organization by SKILL is seen as random by the theory-only scientists.
