Midbrain control of vocalization was evaluated in the ring dove by determining the major afferent inputs with retrograde tract tracing technique. Horseradish peroxidase was infused into various portions of the nucleus intercollicularis, an estrogen concentrating area, which disrupts nest calls when lesioned and induces the vocalization when stimulated by estrogen. Most labelled cell bodies were found in the archistriatum, including a region homologous to the mammalian amygdala.
通过逆行束追踪技术确定主要传入输入，对环鸽中脑发声控制进行了评估。将辣根过氧化物酶注入视丘间核的不同部位，视丘间核是一个雌激素聚集区，损伤时会破坏营巢叫声，雌激素刺激时会诱发发声。大多数标记的细胞体位于古纹状体，包括与哺乳动物杏仁核同源的一个区域。
