How Does Excitation and inhibition of neurons Work?

Neurons talk to each other using excitation and inhibition, like when you shout or whisper to your friend.

Imagine a neuron is like a kid on a swing. When it gets excited, it goes high, that's excitation. It sends a message to the next neuron by sending a spark all the way down its arm (called an axon), which makes the next kid go high too. This happens when something fun or exciting happens.

But sometimes you want to quiet your friend so they don’t keep talking. That’s like inhibition, it’s when something stops the message from going through. It’s like a hand on the swing, slowing it down. If a neuron is inhibited, it doesn’t go as high, and the next kid might not get the full message.

Think of your brain like a big playground with lots of kids. Some shout ("excite") and others whisper ("inhibit"). This mix helps you decide what to do, like whether to laugh or think quietly when someone interrupts your game.

Sometimes, the messages from excitation and inhibition balance out, just like when two friends pull on opposite sides of a rope.
