用放射自显影和电生理学方法研究了非洲爪哇发育过程中双鼻(NN)、双颞(TT)和双腹(VV)复眼的视网膜顶盖投射。早期TT投射仅限于吻侧顶盖，并随着年龄的增长而扩散，在变态后不久覆盖大部分顶盖。早期VV投射显示外顶盖标记密度降低。在发育的所有阶段，早期的NN投射似乎延伸到可用顶盖的整个吻尾长度，但显示出顶盖吻端标记密度的减少。文中还讨论了有关视网膜顶盖连接形成的各种假说。
The retinotectal projections from double-nasal (NN), double-temporal (TT) and double-ventral (VV) compound eyes in Xenopus were studied autoradiographically and electrophysiologically during development. Early TT projections were confined to rostrolateral tectum and spread with advancing age to cover most of the tectum by shortly after metamorphosis. Early VV projections showed a decreased density of label on lateral tectum. Early NN projections appeared to extend across the entire rostrocaudal length of the available tectum at all stages of development, but showed a decrease in label density on rostral tectum. The results are discussed in relation to various hypotheses about the formation of retinotectal connexions.
