Excerpt

We came across this strange word (Latin for “little man,” or we could say “little person”) before, in Francis Crick’s assertion that there is no such entity inside your head that is responsible for and explains the fact of your consciousness—although it can very much feel that way when we get caught up in the sense of I, me, and mine and don’t pay too close attention to who we are talking about, or who is thinking such thoughts, or any thoughts at all for that matter. …

One example of experience-driven neuroplasticity was shown in a study comparing the brains of experienced London cabdrivers with those in training for the licensing exam required to become a taxi driver in London. The posterior hippocampus in the experienced, licensed drivers was much larger and their anterior hippocampus correspondingly smaller than was the case for those training to become cabdrivers, who had not yet learned to get around facilely in the medieval maze of London streets. It turns out that the posterior hippocampus plays a major role in spatial orientation. It seems as if it got physically bigger to “contain” the street map of London, and the related knowledge of all the roundabouts, one-way streets, and intricate traffic patterns. Just for fun, imagine if doing the body scan over and over again were to grow and reshape your somatosensory cortex and other associated regions of the brain in a similar way. With years of practice, we of course become intimately more in touch with the body, and the brain may very well be rearranging itself in response to such a daily discipline. Let’s not forget that your body is far more complex than the layout of London’s streets, that curiously, the cabdrivers call “the knowledge.”
