鸟类鸣叫系统的感觉运动整合对鸣叫的学习和维持至关重要。尽管一些宋系统区域同时表现出感觉和运动特征。它们在听觉和运动前加工中的确切作用尚不清楚。特别是，目前尚不清楚来自nidopallium （NIf）的前脑核界面的输入是否对其靶点HVC的听觉和运动前加工都是必要的，nidopallium （NIf）同时表现出感觉和运动前活动。本研究表明，双侧NIf病变会导致HVC听觉活动的长期丧失，但不会损害歌曲的产生。因此，NIf是HVC听觉输入的主要来源，但完整的NIf对于成年斑胸草雀的运动输出并不是必需的。
Sensorimotor integration in the avian song system is crucial for both learning and maintenance of song, a vocal motor behavior. Although a number of Song system areas demonstrate both sensory and motor characteristics. their exact roles ill auditory and premotor processing are unclear. In particular, it is unknown whether input from the forebrain nucleus interface of the nidopallium (NIf), which exhibits both sensory and premotor activity, is necessary for both auditory and premotor processing in its target, HVC. Here we show that bilateral NIf lesions result ill long-term loss of HVC auditory activity but do not impair song production. NIf is thus a major source of auditory input to HVC, but an intact NIf is not necessary for motor output in adult zebra finches.
