Sensory nerve fibres monitor normal and abnormal stimuli in our body tissues, sending this information to the brain. I study the sensory pathways of the respiratory system which protect the lungs from harmful stimuli, such as inhaled pollutants or smoke. I discovered that respiratory sensory pathways interact with sensory circuits in the brain arising from other body tissues. The goal of this project is to investigate one example of this interaction; the convergence of visceral and somatic sensory pathways onto a brain circuit that regulates the intensity of the sensations that are experienced. This project addresses the fundamental question of how the brain processes two competing noxious sensations.

感觉神经纤维监测身体组织中的正常和异常刺激，将这些信息发送给大脑。我研究了保护肺部免受有害刺激的呼吸系统的感觉途径，例如吸入污染物或烟雾。我发现呼吸道感觉途径与其他身体组织引起的大脑中的感觉电路相互作用。该项目的目的是研究这种相互作用的一个例子。内脏和躯体感觉途径在调节经历的感觉强度的脑电路上的收敛。该项目解决了大脑如何处理两种竞争有害感觉的基本问题。
