Olfaction is crucial for animal survival and human well-being. The olfactory bulb is the obligatory input station for olfactory information. In contrast to the traditional view as a static relay station, recent evidence indicates that the olfactory bulb dynamically processes olfactory information in an experience-dependent and context-dependent manner. Here, we review recent studies on experience-dependent plasticity of the main circuit components within the olfactory bulb of rodents. We argue that the olfactory bulb plasticity allows optimal representations of behaviorally-relevant odors in the continuously changing olfactory environment.

嗅球电路的可塑性。

嗅觉对动物生存和人类福祉至关重要。嗅球是嗅觉信息的强制性输入站。与作为静态中继站的传统观点相反，最近的证据表明，嗅球以依赖于经验和上下文的方式动态处理嗅觉信息。在这里，我们回顾了最近关于啮齿动物嗅球内主要电路组件的经验依赖性可塑性的研究。我们认为，嗅球可塑性允许在不断变化的嗅觉环境中最佳地表示与行为相关的气味。
