在学习发声的鸟类物种中，虎皮鹦鹉被认为是通过基底核（NB）的听觉成分而不是通过经典的丘脑离体通路的终点站L2场接收听觉输入到端脑的发声控制回路中的不寻常。然而，在本研究中，神经追踪技术的应用表明，这两个听觉通路在端脑内是间接连接的。这意味着，因此，在虎皮鹦鹉的发声学习和发声必不可少的听觉信息是来自初级以及次级听觉通路。
Among avian species that learn their vocalizations, budgerigars have been thought to be unusual in receiving auditory input to the vocal control circuitry of the telencephalon via an auditory component of nucleus basalis (NB), rather than via Field L2, the end station of the classical thalamofugal pathway. In the present study, however, the application of neural tracing techniques showed the two auditory pathways to be reciprocally connected within the telencephalon. The implication is, therefore, that auditory information essential for vocal learning and vocal production in the budgerigar is derived from the primary as well as the secondary auditory pathway.
