Okay kiddo, let me tell you about n200 in neuroscience! When we think or do anything, our brains send electrical signals that we can measure with special machines, like an EEG.
Now, the N200 is one of the signals we can see on the EEG. It's like a little wave that appears around 200 milliseconds after we see or hear something important, like a loud noise or a bright light. This wave happens because our brain is working hard to process that information and figure out what it means.
Scientists have found that the N200 wave is especially strong when we see something that we weren't expecting. For example, imagine if you were walking in the woods and you suddenly saw a dinosaur! Your brain would be very surprised and confused, and we would see a big N200 wave on the EEG.
Overall, the N200 is just one way that scientists can learn about how our brains work and how we process information. It's a little wave that tells us when our brain is working extra hard to make sense of the world around us!
