Understanding the sensorimotor control of the endless variety of human speech patterns stands as one of the apex problems in neuroscience. The capacity to learn - through imitation - to rapidly sequence vocal sounds in meaningful patterns is clearly one of the most derived of human behavioral traits. Selection pressure produced an analogous capacity in numerous species of vocal-learning birds, and due to an increasing appreciation for the cognitive and computational flexibility of avian cortex and basal ganglia, a general understanding of the forebrain network that supports the learning and production of birdsong is beginning to emerge. Here, we review recent advances in experimental studies of the zebra finch (Taeniopygia guttata), which offer new insights into the network dynamics that support this surprising analogue of human speech learning and production.
理解人类言语模式的无尽多样性的感觉运动控制是神经科学中的顶尖问题之一。通过模仿快速地将声音有序地组合成有意义的模式的能力显然是人类行为特征中最具衍生性的特征之一。选择压力在众多具有发声学习能力的鸟类物种中产生了类似的能力,并且由于人们对鸟类大脑皮层和基底神经节的认知和计算灵活性的认识不断提高,支持鸟类歌唱学习和产生的前脑网络的一般理解开始出现。在这里,我们回顾了关于斑胸草雀(Taeniopygia guttata)的实验研究的最新进展,这些进展为支持这种与人类言语学习和产生惊人相似的网络动态提供了新的见解。
