在进化的早期,感知和响应不断变化的环境的能力一定为生物体提供了关键的生存优势。从细菌和蠕虫到苍蝇和脊椎动物,复杂的机制已经进化来增强气味检测和定位。在这里,我们回顾了几种趋化性模式。我们进一步考虑无脊椎动物和脊椎动物感觉系统组织中一个引人注目且反复出现的主题的相关性,即两个对称嗅觉传感器的存在。通过结合我们目前关于幼虫和成年果蝇嗅觉回路的知识,我们研究了强大嗅觉感知背后的分子和神经机制,并将这些分析扩展到最近的行为研究,解决双边嗅觉输入与梯度检测的相关性和功能。最后,使用基于布雷滕伯格车辆的比较理论方法,我们推测了解剖结构、电路架构和刻板定向行为之间的关系。
Early in evolution, the ability to sense and respond to changing environments must have provided a critical survival advantage to living organisms. From bacteria and worms to flies and vertebrates, sophisticated mechanisms have evolved to enhance odor detection and localization. Here, we review several modes of chemotaxis. We further consider the relevance of a striking and recurrent motif in the organization of invertebrate and vertebrate sensory systems, namely the existence of two symmetrical olfactory sensors. By combining our current knowledge about the olfactory circuits of larval and adult Drosophila, we examine the molecular and neural mechanisms underlying robust olfactory perception and extend these analyses to recent behavioral studies addressing the relevance and function of bilateral olfactory input for gradient detection. Finally, using a comparative theoretical approach based on Braitenberg's vehicles, we speculate about the relationships between anatomy, circuit architecture and stereotypical orientation behaviors.
