  • Description of Research

    Summary Statement of Research Interests
    Our work is directed towards understanding how the brain contributes to the development, manifestation, and complications of diabetes and obesity. We do this in two projects that focus on the neural control of energy metabolism. The first project investigates how peripheral metabolism interacts with the brain to generate adrenocortical and sympathoadrenal hormonal responses. In particular, we are interested in the way that two critical metabolic signals—glucocorticoid hormones and hypoglycemia—are sensed by the brain, and then generate appropriate counter-regulatory responses. We are interested in how glucocorticoids and neurotransmitters interact with neurons in the hypothalamic paraventricular nucleus, which is a major integrative cell group for metabolic control. A major focus is on sets of hindbrain catecholaminergic neurons that project to the forebrain. These neurons are crucial for detecting and encoding information about blood glucose levels. We investigate the way that catecholaminergic neurons and glucocorticoids affect signal transduction and gene regulatory mechanisms in sets of forebrain neurons. The second project investigates the neural basis of anorexia using dehydration as a physiological challenge. The goal here is to understand the structure and functional interactions between the neural systems that inhibit and stimulate feeding, particularly between the cortex, hypothalamus, and hindbrain. The techniques we use include: whole animal physiology, in situ hybridization, immunocytochemistry (with confocal and conventional immunofluorescence), tract-tracing, behavioral analysis, and neuroinfomatics.
