Your brain “lights up” . . . not
Areas of your brain don’t “light up” or suddenly become active in response to events in the world. “This is an incorrect view of brain activity that dates back to a 1952 study of a piece of a brain cell from a dead giant squid!”

“No human brain cell is ever dormant or switched off. Your whole brain is active all the time. Particular neurons may fire at faster and slower rates, but they’re always in a flurry of activity, dashing off thousands of predictions of what you might encounter next and preparing your body to deal with it. This constant storm of predictions, which scientists call intrinsic brain activity, ultimately produces everything you think, feel, or perceive.”

Thank you for this info from learned scientists. Neuroscience is a large field and quickly growing. It fascinates me. Our brain can increase its capacity by stimulation and learning.
Learning new languages, music, …a multitude of activities will wake up areas that might lay – if not dormant – lazy. 😊

Learning actually grows the brain-new little branches develop from dendrites to link to each other. Learning, exercise and SSRIs (depression medication) all stimulate this growth. So you can have a “bigger” (or denser) brain :-).
