Natural scents are mixtures of tens to hundreds of individual chemical compounds. While previous studies have investigated how the olfactory bulb responds to simple odorants, how the nose and the brain respond to and interpret complex mixtures is less clear. In a paper in this issue of Neuron, Lin et al. combined gas chromatography and intrinsic signal imaging to examine the responses of individual olfactory bulb glomeruli in the mouse to natural odors and their component parts.
天然气味是由数十种到数百种单一化合物混合而成的。虽然此前的研究探讨了嗅球对简单气味剂的反应，但鼻子和大脑如何对复杂混合物做出反应并进行解读却不太清楚。在本期《神经元》杂志上发表的一篇论文中，林等人结合气相色谱法和内在信号成像技术，研究了小鼠单个嗅球肾小球对天然气味及其组成成分的反应。
