摘要

在哺乳动物中,嗅觉感觉神经元检测到的气味信息被转换成嗅球中激活的肾小球的地形图。二尖瓣细胞和簇状细胞依次向嗅觉皮层传递信号,产生行为输出。为了引起先天的行为反应,气味信号由不同的二尖瓣细胞亚群直接从嗅球的特定功能域传递到特定的杏仁核。至于习得的决策,输入信号由簇状细胞和二尖瓣细胞传递到嗅觉皮层。行为场景细胞将气味信息与杏仁核中的价细胞联系起来,从而引发基于记忆的行为反应。嗅觉决定和感知的发生与呼吸循环有关。感官质量是如何强加于嗅觉输入的行为输出的?两种类型的气味信号,先天的和习得的,是如何在呼吸过程中被处理的?本文就小鼠嗅觉系统中参与决策的神经回路的研究进展进行综述。

Olfactory Circuitry and Behavioral Decisions.

In mammals, odor information detected by olfactory sensory neurons is converted to a topographic map of activated glomeruli in the olfactory bulb. Mitral cells and tufted cells transmit signals sequentially to the olfactory cortex for behavioral outputs. To elicit innate behavioral responses, odor signals are directly transmitted by distinct subsets of mitral cells from particular functional domains in the olfactory bulb to specific amygdala nuclei. As for the learned decisions, input signals are conveyed by tufted cells as well as by mitral cells to the olfactory cortex. Behavioral scene cells link the odor information to the valence cells in the amygdala to elicit memory-based behavioral responses. Olfactory decision and perception take place in relation to the respiratory cycle. How is the sensory quality imposed on the olfactory inputs for behavioral outputs? How are the two types of odor signals, innate and learned, processed during respiration? Here, we review recent progress on the study of neural circuits involved in decision making in the mouse olfactory system.
