三项实验检查了鸟类海马旁区（Hp-APH）双边消融的行为影响，该区域被认为是哺乳动物海马结构的同源区域。患有 Hp-APH 损伤的鸽子在学习位置（左/右）辨别的逆转（但不是获得）方面受到损害（实验 1）。相比之下，相对于对照，病变鸟类在视觉（模式）辨别的获取和逆转方面（实验 2）在标准误差方面没有受到损害；然而，有证据表明，在逆转过程中，各组的反应模式有所不同。最后，Hp-APH 鸽子在获得条件歧视方面受到损害（实验 3）。将结果与哺乳动物海马消融的效果进行比较，并考虑它们对鸟类 Hp-APH 和哺乳动物海马结构之间行为同源性的影响。
Three experiments examined the behavioural effects of bilateral ablation of the avian hippocampus-area parahippocampalis (Hp-APH), a region which is considered to be the homologue of the mammalian hippocampal formation. Pigeons with lesions of the Hp-APH were impaired in learning the reversal (but not the acquisition ) of a position (left/right) discrimination (Expt. 1). In contrast, lesion birds were unimpaired relative to controls in both the acquisition and reversal of a visual (pattern) discrimination (Expt. 2) in terms of errors to criterion; there was evidence, however, that the pattern of responding differed between groups during reversal. Finally, Hp-APH pigeons were impaired in the acquisition of a conditional discrimination (Expt. 3). The results are compared with the effects of hippocampal ablation in mammals, and their implications for a behavioural homology between the avian Hp-APH and the mammalian hippocampal formation are considered.
