摘 要: 鸣禽鸟的发声控制脑区具有明显的季节可塑性变化,它是鸣啭季节差异的神经基础.目前鸣禽成鸟的发声控制系统已成为研究中枢神经系统形态和功能可塑性的重要模型.本文着重就引起发声控制核团或脑区体积改变的诱导因素和触发体积改变的机制进行探讨. Excellent examples of seasonal brain changes are found in the avian song control system, which has become a leading model of morphological and functional plasticity in the adult CNS. These changes are the neural substrate for the seasonal behavioral changes of song. In this paper, the cues and mechanisms are focused on which initiate the changes in the avian song control system.
