Autoradiographic analysis of the primary retinofugal projections in the Australian lungfish reveals contralateral retinal projections to a ventral portion of the periventricular preoptic nucleus, throughout its rostrocaudal extent, and to 4 distinct terminal fields in the thalamus. Only one of these thalamic fields (t4) likely receives dendrites solely from dorsal thalamic neurons. Thalamic terminal field 1 probably receives dendrites from both dorsal and ventral thalamic neurons, and fields 2 and 3 from only ventral thalamic neurons. Contralateral retinofugal fibers terminate in the pretectum and in the superficial and central tectal zones. The central tectal terminal field is restricted to the medial one-third of the tectum. At pretectal levels a contralateral basal optic tract arises from the marginal optic tract and terminates along the lateral edge of the tegmentum, as a series of glomerular puffs, and in the rostral pole of a superficial isthmal nucleus. The Australian lungfish, unlike the African and South American lungfish, possesses ipsilateral retinal projections to all of the nuclei that receive contralateral retinal input.
对澳大利亚肺鱼初级视网膜神经纤维投射的放射自显影分析显示，视网膜对室周视前核腹侧部分的投射是对侧性的，贯穿其前后范围，并且在丘脑有4个不同的终末场。这些丘脑中只有一个终末场（t4）可能仅接收来自背侧丘脑神经元的树突。丘脑终末场1可能接收来自背侧和腹侧丘脑神经元的树突，终末场2和3仅接收来自腹侧丘脑神经元的树突。对侧视网膜神经纤维终止于顶盖前区以及顶盖的浅层和中央区。中央顶盖终末场局限于顶盖内侧三分之一处。在顶盖前区水平，一条对侧基底视束从边缘视束发出，沿着被盖外侧缘终止，形成一系列球状膨大，并终止于一个浅层峡核的吻极。与非洲和南美肺鱼不同，澳大利亚肺鱼对所有接受对侧视网膜输入的核都有同侧视网膜投射。
