1.微刺激（在50-400 Hz持续2-4 s的双相电流脉冲的列车）被单方面传递到已知的声音控制区的大脑中的斑胸草雀和金丝雀引起发声。2.简单的发声是从中脑，并从丘间复合体（DM）的背内侧核获得的最低阈值。3.从前脑发声控制核团高级发声中心（HVC）和robustus archistriatalis（RA）引起的发声是复杂的，不仅具有特定的物种，但个别鸟类自己的学习歌曲的功能。4.复杂的声学特征依赖于鸟类发声器官的神经支配，当气管鞘神经被切断时，这些特征就消失了。5.我们认为，刺激前脑声乐途径激活一个专门的神经回路，产生的时间结构的歌曲和其特定的活动模式编程在感觉运动学习过程中，在每个人。
1. Microstimulation (trains of biphasic current pulses at 50-400 Hz lasting 2-4 s) was delivered unilaterally to known vocal control areas in the brains of zebra finches and canaries to elicit vocalizations. 2. Simple vocalizations were elicited from the midbrain, and the lowest thresholds were obtained from the dorsomedial nucleus of the intercollicular complex (DM). 3. Vocalizations elicited from forebrain vocal control nuclei higher vocal center (HVC) and robustus archistriatalis (RA) were complex, with features specific not only to the species, but to the individual bird's own learned song. 4. Complex acoustic features depended on innervation of the bird's vocal organ and were lost when the tracheosyringeal nerve was cut. 5. We suggest that stimulation of the forebrain vocal pathway activates a dedicated neural circuit that generates the temporal structure of song and whose specific pattern of activity is programmed during sensorimotor learning in each individual.
