What is Spike-timing-dependent plasticity (STDP)?

Spike-timing-dependent plasticity (STDP) is like a special memory that helps brain cells learn from each other based on when they fire.

Imagine you and your friend are playing a game where you both have to press buttons. If you press your button just before your friend presses theirs, you get a bonus point, helping you remember that action better next time. But if your friend presses first and then you do, you might lose a point, making it harder to remember that action.

This is exactly what happens with STDP in the brain: when one neuron fires just before another, it helps strengthen their connection, like building a stronger bridge between them. If the order is reversed, the connection gets weaker, like a worn-out bridge.

• Neurons are like little brain cells that send messages.
• A spike is when a neuron fires, it sends an electrical signal.
• If one neuron fires before another, the link between them gets stronger, this is called long-term potentiation.
• If the order is reversed, the link weakens, this is called long-term depression.

STDP helps our brains learn by remembering which actions happen in what order, just like you learning when to press your button for extra points!
