The new neuropsychology of dreaming

What can sleep neurophysiology and the new neuropsychology tell us about lucid dreaming, and how can we use that information to increase our access to that state And what, beyond entertainment, can we learn about the brain-mind from a scientific exploration of lucid dreaming The last question has one ready answer by placing experienced lucid dreamers in a PET scanner (or preferably an fMRI), we could test the hypothesis that, when lucid, dreamers increase the blood flow to their dorsolateral prefrontal cortices as that cortex reactivates to a level consistent with wake state executive function.
