I have a practical kind of question about this kind of research. How do you put a sleeping person in to an MRI machine without waking him/her up?

Usually the fall asleep in the machine.

- People selected don't have sleeping disorders. They must abstain from caffeine and stimulants 24 hours before test.

- Sleep deprivation may be used.

- Ear plugs, active noise cancelation, possibly polyurethane hood in magnet bore

- lower spatial resolution and slower gradient switching speed

When you take measures outside MRI, you may have to play the MRI sound to get comparable results.

The article said they were using cutting edge MRI techniques, whatever that means.
