Mind Hacks: Is the internet making us more intelligent?
I did not read the whole series, but it was interesting. A show from All in the Mind that I just got around to listening to talked about how memory seems to work and the whole hemisphere model is a bit wrong. It seems the right side is more concerned with learning new things, the left side with retaining and recalling things. Still a speculative, but interesting. The bottom line in both cases, though, was that we need to keep trying new things to keep the brain engaged.
