What are postsynaptic neurons?

Postsynaptic neurons are the receivers in the brain’s communication system.

Imagine you and your friend are playing a game where you pass notes to each other under the table during lunch. You write a note, pass it under the table, and your friend reads it, that's like how neurons talk to each other. The neuron that sends the message is called the presynaptic neuron, and the one that gets the message is the postsynaptic neuron.

When a postsynaptic neuron gets a message, it can react, just like your friend might laugh, jump up, or start drawing a picture after reading your note. The message comes in through tiny "doorways" called synapses, and the postsynaptic neuron uses that message to decide what to do next.

Without postsynaptic neurons, your brain couldn’t understand anything, like if your friend never read your notes, the game wouldn't make any sense. These little receivers help us think, move, feel, and learn every day!
