What are the synapse weakens?

A synapse weakens when the connection between two brain cells gets slower or weaker over time, like a phone line that starts to crackle and lose clarity.

Imagine your brain is full of little messengers who run from one room to another, telling each other what to do. These messengers are called neurons, and they talk to each other at special meeting places called synapses, think of them like tiny phone booths where the messengers pass notes.

At first, these messengers shout really clearly, so their friends understand every word. But as time goes on, maybe the messages get quieter, or the phone booth gets dusty and doesn't work as well. That’s when the synapse weakens, it's like a whisper instead of a shout.

This can happen if you don’t use that connection very much, kind of like how a bike gets rusty if you leave it in the garage for too long. The messengers still talk, but they need to work harder to be understood.

Sometimes, this weakening is normal, it's part of growing up or getting older. But if too many synapses weaken at once, it can make things harder to learn or remember, like trying to read a book with all the letters missing!
