Human Ocular Surface Sensory Processing: The surface of the human eye is one of the most sensitive places on the body and yet little is understood about this sensitivity in humans. This proposal is for the continuation of a series of experiments to examine this, with a unique device that blows tiny amounts of a mixture of air and carbon dioxide onto the eye. This device enables us to measure the response in humans to pressure (a scratchy feeling), chemical (burning or stinging) and cold stimulation of the surface of the eye allowing us to to probe the function of those specific types of neural channels.

人眼表面感觉处理：人眼表面是身体上最敏感的地方之一，但对人类的这种敏感性知之甚少。这项提议是为了继续进行一系列的实验来检验这一点，使用一种独特的装置，将少量的空气和二氧化碳的混合物吹到眼睛上。该设备使我们能够测量人类对眼睛表面的压力（发痒的感觉），化学物质（燃烧或刺痛）和冷刺激的反应，使我们能够探测这些特定类型的神经通道的功能。
