RESEARCH SUMMARY
Interest in my laboratory is in the neurobiology of visceral function and ingestive behavior. I am particularly concerned with the neuroanatomical identification and functional evaluation of neural circuits involved in mediating behavioral and physiological control of homeostatic processes. Current research is on 1) use of neurotropic viruses as transsynaptic tract tracing tools to study the visceral neuraxis of the brain, 2) cellular topography of viral transsynaptic movement, 3) electron microscopy of synaptic relations in the vagal complex of the medulla, 4) the visceral afferent and efferent projections of abdominal and thoracic viscera, 5) the circumventricular organs as sites of central receptors and their neural projections, 6)hypothalamic modulation of the autonomic nervous system and the pituitary gland, and its effect on behavior
