Hebbian Theory is a theory that explains how our brains can learn. It suggests that neurons in the brain make connections with each other when they both experience something together. It's like when you're in school and your teacher explains something and keeps repeating it over and over again. After a while, it starts to stick in your head and you remember it much better. The Hebbian Theory says the same thing happens in the brain. When two neurons have similar experiences at the same time often enough, a connection forms between the two neurons. So, the next time the same experience happens, it's easier for the brain to remember it because it already has that connection in place. This is one way our brains learn things and remember them!
