Brain networks processing respiratory sensations
In the respiratory system, sensory neurons are critical for the ongoing physiological control of breathing as well as protecting against potentially damaging stimuli that could adversely affect ventilation. They do so by providing inputs to complex brain networks responsible for generating respiratory sensations and resultant behaviours. Changes in the excitability of these brain networks may be important for the development of coughing, dyspnoea and hyperreactivity characteristic of many lung diseases.
In this project we are mapping the neural connections of airway sensory circuits in the central nervous system and employing physiological models using optogenetics and chemogenetics to better define how respiratory sensations are encoded in the brain.
