Young homing pigeons were subjected to hippocampal lesion before being placed in their permanent loft to examine what effect such treatment may have on the development of their navigational map, which supports homing from distant unfamiliar locations. When later released from 3 distant unfamiliar locations, the hippocampal-lesioned pigeons were impaired in taking up a homeward bearing. The results identify a deficit in the acquisition of navigational ability after hippocampal ablation in homing pigeons. The results strongly suggest a deficit in navigational map acquisition, but alternative interpretations cannot be excluded. The findings offer the first insight into the central neural structures involved in the acquisition of the pigeon navigational map. Further, the results identify the hippocampus as a structure critical for the regulation of navigational behavior that manifests itself in a natural setting.
在将幼龄归巢鸽安置到它们的永久性鸽舍之前，对其进行海马体损伤处理，以研究这种处理对其导航地图发育可能产生的影响，该导航地图有助于从遥远的陌生地点归巢。后来，当从3个遥远的陌生地点放飞时，海马体损伤的鸽子在确定归巢方向上出现障碍。这些结果表明，归巢鸽海马体切除后，其导航能力的获得存在缺陷。结果强烈提示在导航地图获取方面存在缺陷，但也不能排除其他解释。这些发现首次揭示了参与鸽子导航地图获取的中枢神经结构。此外，结果表明海马体是调节在自然环境中表现出来的导航行为的关键结构。
