When a muscle spasms randomly, is the brain telling it to do that or is it doing it on its own?

Question

I’m talking about when your eye twitches or you get a charley horse. Is it your brain mistakenly telling that muscle to move, or is it moving without being told?

Answer 1

I’ve heard that a lot of your random spasms/cramps are a result of magnesium or potassium deficiency.
