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.
