Current Research Areas

Our research focuses on how the brain and the visual system process affective information, and how these processes contribute to the onset and maintenance of stress states and disorders. We take a systems neuroscience approach to translational investigations of the interrelations of the neural circuitry and neuroendocrine cascades associated with stress.

Our goal is to map some of the candidate neurobiological and behavioral mechanisms that underlie maladaptive attention in stress states and stress-related disorders by integrating tools from cognitive science, neuroscience, neuroendocrinology, and clinical science. We examine the interactions of perception (cognition), arousal and valence (affect), and stress states on the continuum from normative to maladaptive (psychopathology). Our long-term goal is an enhanced understanding of the onset and maintenance of symptom episodes in posttraumatic stress disorder, with an ultimate goal of prevention.

Our lab utilizes a variety of methods, including computerized experimental tasks modified from vision science, eye-tracking, immunoassay of saliva analytes, functional magnetic resonance imaging (fMRI), and diffusion weighted imaging (DWI), to investigate the mechanisms underlying both normative and maladaptive affective processing. In particular, we pursue three related lines of research. First, we investigate the role of the allocation of visual attention in stress-related states and disorders using behavioral paradigms developed by vision scientists. Second, we investigate the phenomenology of post-traumatic stress, with particular emphasis on the re-experiencing and hyperarousal symptoms, using measurement methods that include stress hormone assay. Third, we use fMRI and DWI to investigate some of the structural and functional neural systems involved in affective processing in stress states and disorders. Our current work integrates these lines as we work toward mapping the systems and trajectories of pathological affective processing in stress states and disorders.
