Jens is right, it would be very interesting. The scientific part of this wouldn't be too tough. However, the logistics- getting the people together to be tested, finding "normal" non-divers, and the costs of doing the scans and psychometric tests would be the killer. In order to make it scientifically "clean", the divers and controls (I would foresee two groups- recreational divers and non divers as controls) would all have to be tested both in terms of MRI's and psychometrics by either the same medical center, or all of the studies would have to interpreted by the same docs, none of whom could know who was in each group. Basic problem is money. There are two sources of funding for this type of science- big companies who would hope to make a profit from it or some government agency that has funding for the research. We could always get a bunch of guys to go to their doctors and tell them that they're having real bad headaches and get confused easily. The studies would get done, but the "double blind" and quality control wouldn't be there.
