According to the presenter, the problems covered a range of
difficulty from purely random boards to easy problems to hard
problems. All of the problems shown to the subjects were not
given in the paper. The same set of problems were shown to all
subjects.
It would be difficult, but not impossible to conduct a tournament
with the participants inside an MRI machine. MRI machine time
is worth something like $2000 per hour, so cost would add up
quickly.
I agree, it would be very interesting to see if brain volume usage
goes up at the same time the pro uses lots of time.

Question: were the experts analyzing problems which were difficult
at their level, or the same problems analyzed by non-experts? I
suspect that expert players are able to obtain better results for
the same problem with less effort than average players. To borrow
from some now-ancient research done in cognitive psychology at CMU
by Simon, it is probable that one develops cognitive "chunks" which
permit higher-order processing at greater speeds.
It would be interesting to see what percentage of the brain is used
under tournament conditions by expert players, especially when they
need to dig deep into their resources.

At the 3rd International Conference on Baduk there was a paper
presented on fMRI images of the brains of expert and non-expert
players analyzing Go problems. The conclusion of the research
is that experts use far less of their brains than non-experts. The
volume of the brain used by experts is quite small.
