Adult experienced homing pigeons from Maryland were subjected to hippocampal lesion and then transferred to a new loft in Ohio to examine what effect such treatment may have on learning to navigate to a new home loft. When subsequently released from an unfamiliar site, the hippocampal lesioned birds were impaired in taking up a vanishing bearing toward their new Ohio loft. This deficit is interpreted as an impairment in hippocampal-lesioned birds learning a new navigational map. Together with a previous study, the results suggest that an intact hippocampus is necessary if young naive or adult experienced homing pigeons are to learn a navigational map.
来自马里兰州的成年经验丰富的信鸽接受了海马体损伤，然后被转移到俄亥俄州的一个新鸽舍，以研究这种处理可能对学习导航到新的家鸽舍有什么影响。随后，当从一个不熟悉的地点放飞时，海马体损伤的鸽子在朝着它们位于俄亥俄州的新家鸽舍采用消失方位方面存在缺陷。这种缺陷被解释为海马体损伤的鸽子在学习新的导航地图方面存在障碍。与之前的一项研究一起，结果表明，如果幼龄未成熟或成年经验丰富的信鸽要学习导航地图，完整的海马体是必要的。
