Let’s go back to when you were a kid and your parents taught you how to wipe your own butt. The first time you wiped it was awkward, you probably wiped poo poo everywhere and had to concentrate really hard. The neurons in your cerebral cortex were firing in the pattern of butt wiping for the first time. Every time you wiped your butt afterward, the neurons practice. Pretty soon those bunch of neurons that fire whenever you have to wipe your butt form a butt wiping team called a neural network. Today you probably do not even have to think when you wipe your tushy because your neural network has formed such a cohesive team- congratulations!!!
