Sorry I can't provide an absolute answer to your question, but I can only give you my opinion.
As someone has mentioned, neurons are unlike muscle cells that can regrow and replace itself.
But, will inactive neurons die off? That I'm not sure. (It'd be helpful if someone can provide some proof to this)
However, I know for a fact that if one sharpens his/her mind, the brain can be used more efficiently.
Practice makes perfect perhaps?
Correction. Muscle cell can't grow and replace itself.. When you have a tear or an injury on a skeletal muscle, fibrous tissue will grow in it's place, thus replacing the muscle tissue in it's place. Thus you'll never gain 100 percent of it's function back...As someone has mentioned, neurons are unlike muscle cells that can regrow and replace itself.

And why would skeletal muscle seems to grow larger when we go to gym or workout? They undergo hyertrophy which is an increse in cell size, not hyperplasia which is an increase in number of cells...
