as if the brain is highly modular and specific areas of it are involved soley with certain kind of reactions. now, clearly certain parts of the brain are more involved, more heavily in mediating certain kinds of reactions. we know that be the -- but that part of the brain figures prominently in processing perceptions of novelty or surprise, so there's not a one-to-one correspondence. in fact, circuitry where is it is and all neuroscientists know this and i mean again a lot of the problem here is how this -- how popular neuroscience has been -- has come to the media. there's wonderful science journalists who know their background and are very careful and others a little less so. and then there's a whole crop of people called neuro -- neuroentrepreneurs, who are trying to make -- frankly, trying to make a buck off selling things that have to do with education in neuroscience and a lot of fads that one has to be very careful about. so really, circuitry is where it is, and that's where neuroscientists are focusing most of their energy. how the various regions interact with each oomph it's enormo
