项目摘要

In current year, we Attempted to achieve two purposes in our subject, that is, (1) estimation of color discrimination in chick by using of techniques of operant conditioning and (2) elucidation of morphological characteristics of retinal ganglion cells projecting to F-lamina in chick rectum. For the first purpose, we improved the devise for operant conditioning to make the experiment more precise, a starting pedal was newly furnished to the device and a cue pedal was hidden from chick before the test. As a result, we could understand that chick cares for the relation between the food of reward and the position of a cue color pedal rather than the relation between the food and a pre-imprinted cue color(chicks show strong preference for the color that they see first after hatched). This result suggested that chick cared more strongly for information of position in the space innately than acquired imprinting information. In second purpose, we labeled RGCs with antibody against AChR, which send axons to F-lamina of tectum and with florescence axonal tracer, DiI. The labeled RGCs showed the morphological properties of Group IIc, IIIs, and IVc. Particular, Group IVc related to the moving object projected exclusively to F-lamina.

本课题的主要目的是：（1）应用操作性条件反射技术对鸡的颜色辨别能力进行评价;（2）阐明鸡直肠视网膜神经节细胞投射到F层的形态学特征。第一个目的是改进操作性条件反射装置，使实验更加精确，在装置上增加了启动踏板，并在试验前将提示踏板隐藏起来。因此，我们可以理解，小鸡关心的是奖励食物和提示颜色踏板的位置之间的关系，而不是食物和预先印好的提示颜色之间的关系（小鸡对孵化后第一眼看到的颜色表现出强烈的偏好）。这一结果表明，雏鸡对空间位置信息的关注程度比后天获得的印记信息更高。在第二个目的中，我们用抗AChR的抗体标记RGCs，其将轴突发送到顶盖的F层和荧光轴突示踪剂DiI。标记的RGC显示出IIc、IIIs和IVc组的形态学特性。特别是，组IVc涉及的运动物体专门投射到F层。
