That's exactly what I meant actually: combined FMRI and MEG within the same experiment. You get data from each simultaneously and combine them afterwards, using the spatially precise FMRI data to pin down the temporally precise MEG data. It's hard to squeeze a MEG rig into an FMRI machine at the moment, particularly without using ferrous metals (ouch). But I'm sure they'll figure it out in the near future. Hopefully they don't yank off anyone's head in the process. 7 Tesla magnets are scary. -Brad ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
