成人大脑中形成的新神经元被纳入现有的回路中。然而，招募到特定大脑区域的新神经元的数量根据动物的经历而有很大差异。一个新兴的一般原则是，神经元的募集和早期存活可能与大脑区域的活动或使用相关。在这里，我们表明，依赖使用的神经元存活也发生在鸣禽尾内侧巢皮质（NCM）的高阶听觉处理区域。我们认为，年轻神经元的保留可能部分受到系统使用的影响，而不会增加对学习或行为可塑性的需求。
New neurons formed in the adult brain are incorporated into existing circuits. However, the number of new neurons recruited into a given brain region varies widely depending on the experience of the animal. An emerging general principle is that recruitment and early neuronal survival may be correlated with activity or use of the brain region. Here we show that use-dependent neuronal survival also occurs in the higher order auditory processing region of the songbird caudomedial nidopallium (NCM). We suggest that retention of young neurons may in part be influenced by use of the system without an increased demand for learning or behavioral plasticity.
