Research OverviewThe increasing prevalence of obesity has pathological consequences for the health of populations in many countries, both developed and less well developed. In particularly, obesity is often associated with type 2 diabetes (T2D) and cardiovascular disease. For many years the brain's role in generating obesity and diabetes went more or less unrecognized. But much work during the past 25 years has quite clearly identified the brain as both a driver and a target of the complications of obesity and diabetes.
The brain controls eating behavior, and has major influences on the release of energy-controlling hormones, and on liver, pancreatic, gut, and fat (adipose) tissue function. But it also responds, often detrimentally, to the consequences of obesity and T2D. For example, hyperglycemia, hypoglycemia, hyperinsulinemia, insulin resistance, dyslipidemia, and increased inflammatory signals all take their toll on brain function, and in some cases lead to cognitive impairment and increased incidence of Alzheimer?s disease.
To control energy balance and metabolism the brain receives a large number of powerful signals from the environment, the gut, and the bloodstream that it uses to organize appropriate behavioral autonomic, and endocrine functions. In diseases states these functions can be inappropriate and detrimental. The goal of my work is to determine the functional organization of the brain networks that organize and control energy metabolism in response to these signals.
In particularly we are interested in how the brain controls glucose metabolism (particularly in the liver and pancreas), adipose tissue function, and eating behavior. Our overall goal is to understand how the brain is organized to control these key functions and how they change with diabetes and obesity. To do this we use a range of physiologically centered manipulations, selective methods to disrupt the functions of specific neuronal pathways, and sophisticated neural tracing that can reveal the organization of neural connections in exquisite detail.
