121 " Our conscious memory is full of gaps, of course, which is actually a good thing. Our brains filter out the ordinary and expected, which is utterly necessary to allow us to function. When you drive, for example, you rely automatically on your previous experiences with cars and roads; if you had to focus on every aspect of what your senses are taking in, you’d be overwhelmed and would probably crash. As you learn anything, in fact, your brain is constantly checking current experience against stored templates—essentially memory—of previous, similar situations and sensations, asking “Is this new?” and “Is this something I need to attend to?” So as you move down the road, your brain’s motor vestibular system is telling you that you are in a certain position. But your brain is probably not making new memories about that. Your brain has stored in it previous sitting experiences in cars, and the pattern of neural activity associated with that doesn’t need to change. There’s nothing new. You’ve been there, done that, it’s familiar. This is also why you can drive over large stretches of familiar highways without remembering almost anything at all that you did during the drive. This is important because all of that previously stored experience has laid down the neural networks, the memory “template,” that you now use to make sense out of any new incoming information. These templates are formed throughout the brain at many different levels, and because information comes in first to the lower, more primitive areas, many are not even accessible to conscious awareness.
