本实验用放射性顺行示踪剂~ 3 H-脯氨酸对斑胸草雀视顶盖的传出投射进行了研究。除了各种同侧的投射，一些对侧的连接被发现。定量评估的recrossing顶盖-圆形和核subpraetectalis/nucleus apraetico-praetecto-subpraetectalis的投影显示，这些连接比以前认为的要强得多。相反，如前所述，构造-顶盖投影非常弱。对这一点的进一步支持来自使用逆行示踪剂注射获得的结果。不同的预测在传达信息的同侧眼睛的外纹状体，端脑的终端站的tectofugal通路的作用进行了讨论。
SummaryEfferent projections of the optic tectum of zebra finches were investigated by injection of the radioactive anterograde tracer 3H-proline. In addition to a variety of ipsilateral projections, some contralateral connections were found. Quantitative evaluation of the recrossing tecto-rotundal and nucleus subpraetectalis/nucleus interstitio-praetecto-subpraetectalis projection revealed that these connections are much stronger than previously believed. In contrast, the tecto-tectal projection is very weak, as has been shown previously. Further support for this comes from results obtained using injections of retrograde tracers. The role of the different projections in conveying information from the ipsilateral eye to the ectostriatum, the telencephalic end-station of the tectofugal pathway, is discussed.
