在小鼠中,表达给定气味受体的每一类嗅觉受体神经元将其轴突汇聚到嗅球(OB)中的两个特定肾小球上,从而创建气味图。这张地图在嗅觉皮层中是如何表示的?在这里,我们将狂犬病病毒依赖性逆行单突触标记与遗传学相结合,以控制“起始”皮质神经元的位置、数量和类型,从中我们追踪它们的突触前神经元。我们发现单个皮质神经元接收来自代表广泛分布的肾小球的多个二尖瓣细胞的输入。不同的皮质区域代表不同的 OB 输入。例如,皮质杏仁核优先接收背侧 OB 输入,而梨状皮层则对整个 OB 进行采样,没有明显的偏差。这些差异可能反映了这些皮质区域在调节先天气味偏好或联想记忆方面的不同功能。这里描述的跨突触标记方法应该广泛适用于绘制整个小鼠神经系统的连接。
In the mouse, each class of olfactory receptor neurons expressing a given odorant receptor converges their axons onto two specific glomeruli in the olfactory bulb (OB), thereby creating an odor map. How is this map represented in the olfactory cortex? Here we combine rabies virus-dependent retrograde mono-transsynaptic labeling with genetics to control the location, number and type of ‘starter’ cortical neurons, from which we trace their presynaptic neurons. We find that individual cortical neurons receive input from multiple mitral cells representing broadly distributed glomeruli. Different cortical areas represent the OB input differently. For example, the cortical amygdala preferentially receives dorsal OB input, whereas the piriform cortex samples the whole OB without obvious bias. These differences likely reflect different functions of these cortical areas in mediating innate odor preference or associative memory. The transsynaptic labeling method described here should be widely applicable to mapping connections throughout the mouse nervous system.
