果蝇是一个有用的模型映射神经回路的性行为。我们回顾了旨在识别求偶神经回路的细胞成分的研究。回路中的映射功能定义了神经活动和行为之间的因果关系。光遗传和热遗传策略对于识别能够引起求爱的命令元件至关重要。构建一个全面的结构,重要的是形成大脑的元素和连接网络的功能图代表了不同学科研究小组的圣杯。虽然技术上的限制限制了人类和小鼠的“连接体”的映射到大脑区域的水平,一个更好的程度的功能分辨率是可以达到的果蝇,黑腹果蝇,由于该模式生物的遗传工具的医疗设备。目前,果蝇神经生物学家采用的最可行的方法之一是绘制复杂的先天行为背后的神经元回路-求爱是一个经典的范例。我们讨论了最近的研究,旨在确定求偶神经回路的细胞成分,在这些电路中的映射功能,并定义神经活动和行为之间的因果关系。
► Drosophila is a useful model for mapping neuronal circuitry underlying sexual behavior. ► We review studies aimed at identifying the cellular components of courtship neural circuits. ► Mapping function in circuits defines causal relationships between neural activity and behavior. ► Optogenetic and thermogenetic strategies have been pivotal for the identification of command elements capable of eliciting courtship. The construction of a comprehensive structural, and importantly functional map of the network of elements and connections forming the brain represents the Holy Grail for research groups working in disparate disciplines. Although technical limitations have restricted the mapping of human and mouse ‘connectomes’ to the level of brain regions, a finer degree of functional resolution is attainable in the fruit fly, Drosophila melanogaster, due to the armamentarium of genetic tools available for this model organism. Currently, one of the most amenable approaches employed by Drosophila neurobiologists involves mapping neuronal circuitry underlying complex innate behaviors – courtship being a classic paradigm. We discuss recent studies aimed at identifying the cellular components of courtship neural circuits, mapping function in these circuits and defining causal relationships between neural activity and behavior.
