The best thing today is probably an EEG system; you will get a rough idea
of what is going on but hardly any information about which part is more
active than another. Functional methods have so far been rather unwieldy,
static and expensive.
There are several EEG systems on the market that can be used, myself I'm
involved in a very slow moving project to build the Brainmaster interface
(try making a web search on it).
