1.鸽卵圆核是下丘臂的主要间脑末梢（中脑外侧核，2.用Nauta-Gygax和Fink-2000神经纤维仪研究了立体定向毁损卵圆核后的纤维变性。3.卵圆核的传出轴突形成外侧前脑束的内侧部，4.散在分布的卵圆肌轴突终止于枕内侧囊（capsule occipitalis interna，CIO）的闰层神经元和新纹状体内侧尾侧。然而，到目前为止，卵形投射的主要分布发生在内侧尾侧新纹状体的一个界限分明的区域，该区域由小而密集的神经元组成。5.结合前人对鸟类下丘听觉投射的研究，发现鸟类下丘经丘脑卵圆核至前脑存在一条分离的听觉投射通路。6.讨论了鸟类和哺乳动物上行听觉通路的关系。
1.The nucleus ovoidalis of the pigeon is a major diencephalic terminus of the brachium of the inferior colliculus (nucleus mesencephali lateralis, pars dorsalis).2.The fiber degenerations following stereotaxic lesions of the nucleus ovoidalis were studied with the Nauta-Gygax and Fink-Heimer methods for degenerating axons and boutons terminaux.3.Efferent axons of the nucleus ovoidalis form the medial portion of the fasciculus prosencephali lateralis and pass through the medial part of the paleostriatum augmentatum to enter the overlying capsula occipitalis interna (CIO).4.Some scattered ovoidalis axons terminate on the intercalated neurons of the CIO, and in the medial caudal neostriatum. By far the major distribution of the ovoidal projection, however, takes place in a sharply demarcated region of the medial caudal neostriatum, consisting of small, densely packed neurons. This region corresponds to Field L of Rose.5.This study, taken in conjunction with an earlier report on the projections of the avian inferior colliculus, indicates the existence of a discrete and sharply segregated auditory projection pathway leading from the inferior colliculus over the thalamic nucleus ovoidalis to the forebrain.6.The relationships between avian and mammalian ascending auditory pathways are discussed.
