CAT scan

Does any body know if enlightenment would show up on a CAT scan?
Anybody remember seeing anything posted online?

I'm not sure about CAT scans, Owen was just in a study using fMRI:

mumuwu just posted some lectures/talks regarding enlightenment and changes to the brain:

This may have info on CAT scans specifically, I've only watched the first 30 minutes or so.

CAT Scans are essentially glorified XRAYs, that is the radiation they use. They are good for uncovering bone and other hard tissue changes. They also show gross (very readily apparent) events such as bleeds. MRI looks at changes in soft tissues such as muscle, skin swelling. It can also show some minor brain changes.

The only scan that really shows any of a "functioning" tissue in vivo is fMRI or functional MRI.

www.fmri.org/fmri.htm
Functional MRI is based on the increase in blood flow to the local vasculature that accompanies neural activity in the brain. The main advantages to fMRI as a technique to image brain activity related to a specific task or sensory process include 1) the signal does not require injections of radioactive isotopes, 2) the total scan time required can be very short, i.e., on the order of 1.5 to 2.0 min per run (depending on the paradigm), and 3) the in-plane resolution of the functional image is generally about 1.5 x 1.5 mm

Richard J. Davidson at U Wisconsin Madison has looked at fMRI imaging of Tibetan Monks.

In terms of how that would be able to show whether someone is enlightened - I don't think the technology is there yet.

Thanks this is very helpful everybody!
