My laboratory is engaged in anatomical, behavioral and physiological
experimentation to identify metabolic events that control the onset of
feeding behavior and the neural pathways responsible for monitoring
these events. In our work, we utilize drugs which stimulate feeding by
selectively blocking intracellular utilization of glucose or fatty
acids. Although these drugs block metabolism of glucose and fatty acids
throughout the body, stimulation of feeding results from their action on
specific metabolic receptor cells.
Our work is focused on localization of these metabolic receptor cells
and on tracing the neural pathways from these receptors to parts of the
brain which organize feeding behavior. Understanding the basic anatomy
and physiology of these particular metabolic controls of food intake
will contribute importantly to the overall view of how the nervous
system integrates feeding behavior, metabolism and body weight and
ultimately achieves metabolic homeostasis.
