It is important to know that EEG and MEG are complementary, but they together are much better than IQ and Neurologic score: I advise to read the following paper:

Thanks very much, I agree. It seems that nowadays the way of making an EEG or MEG is much more elegant than in 1998, when we did our study. Now  a hood has sensors with wireless contact with the computer, so it can be done more easily than 15 years ago. As ever janna
