    Behav Neurosci 125:626-31. 2011
    ..Further, these findings suggest that although UCR amplitude is modified by conscious expectations of the UCS, conditioned diminution of the UCR can be expressed independent of learning-related changes in these expectations...

    David C Knight
    Section on Functional Imaging Methods, Laboratory of Brain and Cognition, National Institute of Mental Health, Bethesda, MD 20892, USA

    Section on Functional Imaging Methods, Laboratory of Brain and Cognition, National Institute of Mental Health, Bethesda, MD 20892, USA
    Neuroimage 45:208-14. 2009
    ..These findings demonstrate the distinct roles of these brain regions in explicit and implicit fear memory processes...

    David C Knight
    Unit on Functional Imaging Methods, Laboratory of Brain and Cognition, National Institute of Mental Health, Building 10, Room 1D80, Bethesda, MD 20892, USA
    Neuroimage 26:1193-200. 2005
    ..These results suggest the amygdala not only responds to fearful stimuli, but also generates learning-related changes in human autonomic fear expression...

    Proc Natl Acad Sci U S A 100:15280-3. 2003
    ..These data indicate that conditional fear can be expressed when individuals are unaware of fear-eliciting stimuli and suggest that the degree of conditioning is independent of awareness during differential Pavlovian fear conditioning...
