In my country there is a fairly common expression "det sitter i ryggmärgen" literally "it's in the spinal cord" which means that you have practiced something a whole lot and know it by heart. The implication being that the spinal cord can do the task on its own without involving the brain. It's so common that it wouldn't surprise me if 1st grade teachers used it without even reflecting on the literal meaning.

Now whether the spinal cord actually can learn motor skills seems to be a bit of an open question, but it can perform some instinctive tasks like shying away from painful stimuli.

Love that expression.

There’s a book, The Talent Code. One of the central premises is neuroplasticity and more precisely the process of muslin “wrapping” certain neuropathways making them more efficient.

This happens all the time - for connections deemed by the brain as important. While demoting “unimportant” ones.

So yes, the brain undergoes constant change - iterating on continuous improvement.

Intentional practice activates this process.

This, what we call “talent”, more often than not, is the result of intentional practice.

Mialin, not muslin obviously.
