In a series of retrograde tracing studies involving the injection of WGA-HRP into the thalamus of the pigeon, labeled neurons were consistently observed in anterior regions of the vestibular nuclei. Following small dorsal thalamic injections, labeled neurons were located predominantly in rostroventrolateral regions of the superior vestibular nucleus, less numerously within the ventral part of the lateral vestibular nucleus, and least numerously within the medial vestibular nucleus. Following large dorsal thalamic injections, many more vestibular neurons were labeled, and these were distributed more extensively throughout anterior parts of the superior, lateral, and medial nuclei. No labeled neurons were found in the descending nucleus. Injections of tritiated amino acids into vestibular nuclei revealed a terminal field within the dorsal thalamic nucleus: dorsolateralis posterior, pars rostralis. The location of this field between auditory, somatosensory, and paleostriatally and neostriatally projecting nuclei suggests a general similarity to the organization of vestibulothalamic projections in mammals.
在一系列涉及将WGA-HRP注入鸽子丘脑的逆行追踪研究中，在前庭核的前部区域始终观察到标记神经元。在丘脑背侧进行小剂量注射后，标记神经元主要位于前庭上核的嘴侧腹外侧区域，在外侧前庭核腹侧部分数量较少，而在内侧前庭核中数量最少。在丘脑背侧进行大剂量注射后，标记的前庭神经元更多，并且这些神经元更广泛地分布在上核、外侧核和内侧核的前部。在下行核中未发现标记神经元。将氚化氨基酸注入前庭核后，在丘脑背侧核：后外侧背核嘴侧部内发现了一个终末区。该区域在听觉、躯体感觉以及向古纹状体和新纹状体投射的核之间的位置表明，它与哺乳动物前庭丘脑投射的组织方式总体相似。
