Three experiments investigated the role of the pigeon hippocampal formation (the hippocampus and area-parahippocampalis) in short-term memory for non-spatial and spatial information. The acquisition of delayed matching-to-sample and the short-term retention of non-spatial visual information, using a small set of sample stimuli, were unaffected by aspiration lesions of the hippocampus or the neostriatum (Experiment 1). Similarly, acquisition and short-term retention of non-spatial information using a successive, trial-unique, delayed non-matching-to-sample procedure were unaffected by hippocampal damage; the same birds had, however, displayed a profound autoshaping impairment (Experiment 2). Acquisition of a spatial delayed matching-to-sample task was unimpaired by hippocampal damage. However, lesioned animals were impaired following the introduction of retention intervals on this procedure (Experiment 3). The correspondence between the behavioural effects of hippocampal lesions in birds and mammals on short-term memory is discussed, and the implications of these results for avian hippocampal function are considered.
三项实验研究了鸽子海马结构（海马体和海马旁区域）在非空间信息和空间信息短期记忆中的作用。使用一小套样本刺激进行延迟匹配样本任务的习得以及非空间视觉信息的短期保持，均不受海马体或新纹状体吸出损伤的影响（实验1）。同样，采用连续、每次试验独特的延迟非匹配样本程序时，非空间信息的习得和短期保持也不受海马体损伤的影响；然而，同样的鸟类在自动塑造方面表现出严重损伤（实验2）。空间延迟匹配样本任务的习得不受海马体损伤的影响。但是，在此程序中引入保持间隔后，损伤动物出现了损伤（实验3）。讨论了鸟类和哺乳动物中海马体损伤对短期记忆行为影响之间的对应关系，并考虑了这些结果对鸟类海马体功能的意义。
