$1 million plus for the low-end, I think. It's hard to find price lists online. The companies' websites brag about having "30 installed units" and things like that, so its not cheap stuff, that's for sure. > > > > > *the physical resolution is amazing (down to a few cubic milimeters > with the latest > > equipment) but the time-resolution sucks compared to EEG--minutes vs > .01 seconds-- > > and samadhi lasts only a few seconds to a minute. > > > Lets hope those 80 core processors hit the market soon. > > But on that, I have seen brain images on TV that seem to change in > real time.

There's MEG (magnetoencephlography) that is real-time. http://www.ctf.com/products/meg/overview/technology.htm and I'm sure there's other stuff I've never heard of.

I think that there's some PET work with Daniel Amit on ADHD as well. He's in Iowa, IIRC. Things may change due to that pain study. Cho is co-inventor of PET, IIRC and is a pioneer in newer brain imaging techniques. If they can get him to work with them on future TM studies it may open a LOT of doors. http://www.senate.uci.edu/5_FacAwards/03_4Awrds/ChoBio.htm Neuroreport. 2006 Aug 21;17(12):1359-63. Links Neuroimaging of meditation's effect on brain reactivity to pain. Orme-Johnson DW, Schneider RH, Son YD, Nidich S, Cho ZH. Institute for Natural Medicine and Prevention, Maharishi University of Management, Fairfield, Iowa, USA. [EMAIL PROTECTED] Some meditation techniques reduce pain, but there have been no studies on how meditation affects the brain's response to pain. Functional magnetic resonance imaging of the response to thermally induced pain applied outside the meditation period found that long-term practitioners of the Transcendental Meditation technique showed 40-50% fewer voxels responding to pain in the thalamus and total brain than in healthy matched controls interested in learning the technique. After the controls learned the technique and practiced it for 5 months, their response decreased by 40-50% in the thalamus, prefrontal cortex, total brain, and marginally in the anterior cingulate cortex. The results suggest that the Transcendental Meditation technique longitudinally reduces the affective/ motivational dimension of the brain's response to pain.
