    Research Summary

    Our research is focused on the function and plasticity of distributed, brainstem neural networks involved in cardiorespiratory control. Behaviors of interest include the production of airway protective reflexes such as cough as well as responses to hypoxia, hyper- and hypo-capnia, and lung inflation. Our methods include extracellular spike train recording in vivo, computer assisted data entry and analysis (statistical measurement of cardiorespiratory modulation, cycle triggered histograms, cross correlograms, spike triggered average histograms, and the gravity method) and computer simulations of neural networks inferred from in vivo data.
