Black Nadel和O‘Keefe(1977)提出海马体在行为中的主要功能是进行空间映射，即提供构成地点策略基础的认知地图。他们回顾了这样的策略在某些回避和惩罚情况下发挥作用的证据，以及海马体损伤影响这些策略，而不影响源自时间加工的线索策略。支持空间映射假说的证据是根据另一种概念来检验的，即海马体使动物能够忽略(调谐)无关的刺激和事件。尽管这种特别分析有其局限性，但有一种观点认为，空间学习的缺陷可能最终归因于(A)在无关刺激的控制下低效反应模式的持续存在，以及(B)由于不相关的不协调事件的干扰而导致的联想学习失败。有人认为，海马体是处理空间和时间信息的一般系统的一部分。
Black Nadel, and O’Keefe (1977) have proposed that the main function of the hippocampus in behavior is to engage in spatial mapping, i.e., to provide the cognitive maps which form the basis of place strategies. They review evidence that such strategies play a role in certain avoidance and punishment situations and that hippocampal damage affects these strategies while leaving unaffected cue strategies derived from temporal processing. The evidence supporting the spatial mapping hypothesis is examined in terms of an alternative notion, namely, that the hippocampus enables the animal to ignore (tune out) irrelevant stimuli and events. Despite the limitations of such ad hoc analyses, a case is made that deficits in spatial learning might ultimately be traced to (a) persistence of inefficient modes of responding under the control of irrelevant stimuli and (b) failures of associative learning due to interference from irrelevant incongruous events. It is suggested that the hippocampus is part of a general system that processes information in both space and time.
