I want to let you in on a little secret. We neuroscientists are actually quite jealous of the physicists. They may lament the fact that their unified theory of everything hasn’t turned up yet, but they’re sitting pretty with a bevy of universal laws, forces, constants and equations that do a bang up job explaining the universe. We neuroscientists are still on the hunt for some all-encompassing laws and principles that would explain brain function at a larger scale than the operation of single neurons (on which, I must say, we’ve done a pretty awesome job).
