Motor skills trigger two distinct physical brain changes
Learning a new physical task causes brain cells to temporarily swell before building a permanent network of dense connections in motor regions.
When you learn a new motor skill, your brain undergoes a physical transformation that occurs in two distinct stages. The first is a rapid, temporary expansion of cell bodies across every region of the brain involved in the task. This widespread swelling acts as a short lived homeostatic response, essentially a burst of cellular activity that prepares the brain for the work of learning.
