Commutative (neurophysiology)
Let's pretend you have two toys, a red ball and a blue car. You could either play with the red ball first and then the blue car, OR you could play with the blue car first and then the red ball. And guess what? It doesn't matter which one you do first because the end result is the same - you'll have played with both toys! This is what we call "commutative."
In neuroscience, "commutative" means that the order of things happening in your brain doesn't affect the final outcome. For example, if one neuron (that's a tiny brain cell) sends a message to another neuron and then that neuron sends a message back, it doesn't matter which one happens first - you'll still get the same final result.
So just like with your toys, the order of things happening in your brain can be commutative. Whether one neuron sends a message first or another neuron sends a message first, the end result will be the same.
