fMRI

[Guest guest]

Todd: What would the functional MRI (fMRI) map of the brain

look like in gan qi yu jie? What parts of the brain would

demonstrate changes in activity in response to coursing the

liver and rectifying qi? Or, would both of these questions be

answerable only by comparing pre- and post-treatment images?

 

Sean: My understanding (based on my reading of the reference

below) is that the subjects were only partially placed into the

fMRI tube (headfirst). Under " Materials and Results, " mention

is made of a " standard head coil. " Only brain images were

obtained; only foot points were needled (outside the tube).

Thus there were no needles within the magnetic field of the

fMRI.

See Cho ZH et al, " New findings of the correlation between

acupoints and corresponding brain cortices using functional

MRI, " Proc Natl Acad Sci USA 1998;95:2670-2673. A seminal work.
