Every time you experience something new, electrical charges fire through the white matter in tour brain, creating chemical links that form a network of pathways out of neurons. Your memories are stored in these connected neurons, and the connections become stronger and expand into other neurons with repeated exposure to the new experience. Practicing a song on the guitar makes the same neural networks fire again and again, becoming stronger and thus making the song easier to play. Spending time with a new friend reinforces old connections and builds new ones as you learn about your pal’s habits. As you learn and gain new memories, your brain’s structure changes and makes new connections. The brain you have today will be different tomorrow.
