The biology of fish olfaction: amino acids and Ga-proteins

嗅觉（嗅觉）是生物体从其环境中收集信息的主要途径。 外部线索可以引起各种各样的反应，从内部生理调整到复杂的行为。在鱼类中，溶解的氨基酸是许多行为所必需的，从食物定位，到捕食者回避，再到迁移。 目前，我们知道氨基酸可以被三种形态上不同的感觉神经元检测到，但不知道的是这些不同的神经元如何协同工作以引起行为反应。我研究的中心目标是帮助解决这个嗅觉难题，通过描述哪种类型的嗅觉感觉神经元受体对哪种气味做出反应，最终唤起给定的结果？

The sense of smell (olfaction) is a major route by which organisms gather information from their environment. The external cues can induce a diverse array of responses, ranging from internal physiological adjustments to complex behaviours. In fish, dissolved amino acids are essential do numerous behaviours, ranging from food location, to predator avoidance, to migration. At present we know that amino acids can be detected by three morphologically distinct sensory neurons, but what is not known is how these different neurons work together to evoke behavioural responses. The central goal of my research is to help solve this olfactory puzzle, by characterizing what type of olfactory sensory neuron receptor responds to which odorant to eventually evoke a given outcome?
