Opposition spike

Okay kiddo, you know how sometimes when you're playing a game with your friends, you want to do something different from what they want to do? It's like you have an opposite idea from theirs. Well, that's kind of what happens in our brains too.

Our brains have lots of nerve cells called neurons that talk to each other to help us do everything, like walk, talk, and even think. And sometimes when one group of neurons wants to do something, another group of neurons will say "wait, I don't think that's such a good idea." That's called opposition.

When lots of neurons all start saying "wait, stop, don't do that" at the same time, it creates a big burst of activity in our brains which is called a spike. And that's what an opposition spike is. It's when a bunch of neurons all signal at once to block an action or thought.

Opposition spikes help our brain decide what to do and what not to do, like when we need to make a choice between different things. And scientists study these spikes to learn more about how our brains work.
