我们的感官体验的很大一部分发生在主动行为中，比如四处走动或集中注意力。在这些行为中，感觉系统是如何工作的？感觉系统中的神经处理可以通过多种方式由行为塑造，从反应性的调制或调谐的锐化到反应特性或功能连接的动态变化。在这里，我们回顾了最近的研究结果，在不同的系统：昆虫视觉，啮齿动物丘脑和啮齿动物感觉皮层的主动行为过程中的感觉处理的调制。我们讨论了电路水平的机制，可能导致这些调制和它们在感觉功能的潜在作用。最后，我们强调了这个令人兴奋的新领域的开放性问题和未来前景。
A substantial portion of our sensory experience happens during active behaviors such as walking around or paying attention. How do sensory systems work during such behaviors? Neural processing in sensory systems can be shaped by behavior in multiple ways ranging from a modulation of responsiveness or sharpening of tuning to a dynamic change of response properties or functional connectivity. Here, we review recent findings on the modulation of sensory processing during active behaviors in different systems: insect vision, rodent thalamus, and rodent sensory cortices. We discuss the circuit-level mechanisms that might lead to these modulations and their potential role in sensory function. Finally, we highlight the open questions and future perspectives of this exciting new field.
