Okay, so inside your brain there are little things called neurons that help your brain work. Neurons are like little electric wires that send messages around your brain so you can think and feel things.
Sometimes, when a neuron gets damaged or needs to grow in a certain direction, it can move towards an electric current like a magnet. This is called neuronal galvanotropism. It's like if you were playing with a toy car and you put a magnet on one side of the room, the car would roll towards it.
But neurons are much more complicated than toy cars. They have special proteins on their surface that can sense the electric fields around them and help them move in the right direction. This is important because if neurons didn't move in the right way, your brain might not work correctly.
Scientists are studying neuronal galvanotropism to learn more about how neurons grow and develop, and how we might be able to help them when they get damaged. So it's like they are detectives looking for clues to solve the mystery of how our brains work!
