My research interests in emotion are in understanding the physiological, neuroanatomical and molecular bases of fear and anxiety. To approach these problems, we study fear-related behaviors that have defined neuroanatomical circuits, such as fear-potentiated startle and fear-induced freezing or immobility in rats. Experiments are designed to study the pharmacology, biochemistry and molecular biology of fear within the neural circuits that mediate these fear-related behaviors. We use numerous techniques including brain stimulation and lesions, anatomical tracing, administration of drugs, and detection of proteins and messenger RNA using in situ hybridization, immunohistochemistry, and Northern and Western blotting.
