What is neurotransmission?

Neurotransmission is how your brain sends messages from one nerve cell to another, like a brain-to-brain phone call.

Imagine you're playing with building blocks. When you want to tell your friend to bring more blocks, you shout across the room. That’s like how neurons, or brain cells, talk to each other when they’re far apart.

How it works

When one neuron wants to send a message, it releases special messengers called neurotransmitters, think of them like tiny bubbles full of "Hey, I need help!" signals. These bubbles float across a little gap between two neurons, called the synapse, and land on the next nerve cell.

The receiving neuron gets the message and can now do something, like making your hand move or helping you remember a song.

The brain's everyday helper

It’s just like when you press a button on a remote control. The signal goes through wires (or, in your brain, through neurotransmitters) to make the TV turn on. Your brain uses neurotransmission every time you laugh, walk, or even blink, it’s the reason you can do all those cool things without thinking about it!
