Research in the Zahner Neurophysiology Laboratory focuses on neural regulation of blood pressure, energy balance and metabolic activity in healthy and diseased states. More specifically, we are focused on characterizing the autonomic activity of cells within the brain, the neurotransmitters, and the neural networks that differentially control reflex responses that people typically take for granted when they are working properly. Another part of our research focuses on disorders that are directly affected by obesity and disorders of the nervous system such as cardiac pain, sleep apnea, and hypertension.
To do this research our lab uses cutting-edge electrophysiological approaches, histological assessments, and microinjection of viruses that can manipulate the genetics and activity of specific types of neurons. In addition to these laboratory approaches we also use radio-telemetry technology and computational approaches to non-invasively record cardiovascular and metabolic activity. Projects are also being designed to determine the beneficial effects of neurostimulation to improve metabolic and cardiovascular activity.
