The Laboratory for Neuroimaging of Anxiety and Respiratory Psychophysiology uses neuroimaging modalities to study the pathophysiology and treatment of mood and anxiety disorders. As a complement to our research efforts in mood and anxiety the laboratory holds particular scientific interest and expertise in the neuroimaging of respiratory and autonomic stress responses. We currently utilize functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) to study healthy volunteers and subjects with anxiety disorders. Our studies employ cognitive activation, mood induction, and respiratory symptom provocation paradigms, while acquiring neuroimaging and psychophysiological data. These studies allow us to enhance our understanding of normal emotional processing and respiratory symptom perception as well as abnormalities in affective and/or cognitive processing in subjects with mood and anxiety disorders.
