前脑和脑干回路如何相互作用以产生时间上精确和可重复的行为？鸟鸣是由前脑和脑干核团网络控制的一种复杂的、时间精确的和刻板的发声行为。一个有影响力的想法是，在前脑核（HVC）的歌曲运动前神经元形成一个突触链，决定歌曲的时间在一个自上而下的方式。在这里，我们结合联合收割机的生理，动力和计算的方法来表明，歌曲的时机是不是仅仅由本地化的机制，以HVC，而是一个分布式的和经常性的突触网络跨越前脑和脑干，其中HVC是一个组件的产品。
How do forebrain and brainstem circuits interact to produce temporally precise and reproducible behaviors? Birdsong is an elaborate, temporally precise and stereotyped vocal behavior controlled by a network of forebrain and brainstem nuclei. An influential idea is that song premotor neurons in a forebrain nucleus (HVC) form a synaptic chain that dictates song timing in a top-down manner. Here we combine physiological, dynamical and computational methods to show that song timing is not generated solely by a mechanism localized to HVC but instead is the product of a distributed and recurrent synaptic network spanning the forebrain and brainstem, of which HVC is a component.
