Injections of HRP throughout the upper tectal strata led in 4 cases to the appearance of retrogradely labeled neurons within n.isthmi ventralis, contralateral to the experimental side. An additional case proved that this projection courses through the ventral supraoptic commissure. This is the first description of a crossed isthmo-tectal projection in birds.
在4例实验中，将辣根过氧化物酶注射到上丘的各层，结果在实验侧对侧的峡核腹侧部出现了逆行标记的神经元。另外1例实验证明，这一投射经视上连合腹侧部走行。这是鸟类中交叉性峡核-顶盖投射的首次描述。
