Is there any information on the brain activity of a Lucid Dreamer opposed to a non Lucid Dreamer? Perhaps certain braincentres being more active and indications of certain brainchemicals being released/inhibited, or released in higher/lower than usual quantities? And specifically to point out the difference between the brainchemistry of Lucid dreaming and non lucid dreaming?

Only then could we begin to see what brainchemicals should be decreased/increased and by what supplements those changes would be caused. Cheese, Garlic, Melatonin....all illusive and irreliable to me.

anyone?
