Twelve normal male subjects were injected with 18 F D-deoxyglucose during either rapid eye movement (REM) (N = 7) or non-rapid eye movement (NREM) (N = 5) sleep, When subsequently awakened they reported their dreams and mentation, which were taperecorded, transcribed, and then coded along dimensions of perceived control. Non-parametric correlations between these verbal reports and localized cerebral glucose metabolic rates obtained from Positron Emission Tomography (PET) scores revealed significant positive and negative correlations throughout the brain. Having control was positively associated with activation of frontal cortex components and negatively correlated with limbic system activation. Showing internal consistency, there was a significant positive correlation between loss of control and limbic system activation, and a significant negative correlation between loss of control and the frontal cortex (right). Potential implications and importance of these findings for the study of control and state specific consciousness, clinical problems such as depression, brain lateralization, and further PET studies are discussed.
