The present work analyzes the involvement of telencephalon of goldfish in spatial strategies, using a procedure analogue to the hole-board task. With this aim, goldfish with sham operation or telencephalon ablation were trained to find a baited feeder within a twenty-five feeder matrix, which maintained stable spatial relationships relative to five peripheral landmarks. After training, different types of probe tests were conducted. Although both groups learned the task, probe trials showed that whereas the sham animals used the whole configuration of cues to implement map-like strategies the telencephalic animals used a guidance strategy based on cues located in the vicinity of the baited feeder. These results confirm the role of teleost fish telencephalon in the use of allocentric strategies obtained with other spatial procedures, and indicate that the hole-board task described here for goldfish is a useful tool to assess the neural bases of spatial cognition in teleost fish.
本研究采用类似于洞板任务的程序，分析金鱼端脑在空间策略中的参与情况。为此，对进行假手术或端脑切除的金鱼进行训练，使其在一个由25个喂食器组成的矩阵中找到一个装有诱饵的喂食器，该矩阵相对于五个周边地标保持稳定的空间关系。训练后，进行了不同类型的探针测试。尽管两组都学会了任务，但探针试验表明，假手术动物利用整个线索配置来实施类似地图的策略，而端脑切除动物则使用基于诱饵喂食器附近线索的引导策略。这些结果证实了硬骨鱼端脑在使用通过其他空间程序获得的以自我为中心的策略中的作用，并表明此处描述的金鱼洞板任务是评估硬骨鱼空间认知神经基础的有用工具。
