The pattern of retinogeniculate connections has been examined in a range of diprotodont marsupials, including wallabies, possums, forest wombat and koala. The lateral geniculate nucleus (LGd) in most species has alternating bands of ipsilateral and contralateral retinal terminal fields, with considerable interspecific variability. The number of terminal bands of retinogeniculate input varies from eight to eleven in most species, with little binocular overlap. By contrast in one species, the feather-tailed glider, the most significant feature of LGd organisation is binocular overlap. No relationship is apparent between LGd organisation and the life-style of the animals.
人们已经在一系列双门齿有袋动物中研究了视网膜与膝状体的连接模式，这些动物包括沙袋鼠、负鼠、毛鼻袋熊和树袋熊。大多数物种的外侧膝状体核（LGd）具有同侧和对侧视网膜终末场的交替带，种间差异很大。在大多数物种中，视网膜膝状体输入的终末带数量从八条到十一条不等，双眼重叠很少。相比之下，在一种动物——羽尾袋鼯中，LGd结构的最显著特征是双眼重叠。LGd结构与动物的生活方式之间没有明显关系。
