In 3 pigeons ablation of the posterodorsolateral neostriatum impaired delayed alternation without affecting visual discrimination. In mammals the same selective deficit is produced by lesions in the prefrontal system. The presently ablated neostriatal region resembles the mammalian prefrontal cortex also by being richly innervated with dopaminergic fibers. This region is clearly separated from paleostriatum augmentatum and archistriatum which also have a strong dopaminergic innervation. The presence of a prefrontal cortex-like formation in a bird species raises the possibility that all higher vertebrates are equipped with this neural device.
在3只鸽子中,后外侧新纹状体的切除损害了延迟交替反应,而不影响视觉辨别。在哺乳动物中,前额叶系统的损伤会产生同样的选择性缺陷。目前切除的新纹状体区域与哺乳动物前额叶皮层相似,也有丰富的多巴胺能纤维支配。该区域与苍白球增大部和古纹状体明显分开,而苍白球增大部和古纹状体也有很强的多巴胺能神经支配。鸟类中存在类似前额叶皮层的结构,这增加了所有高等脊椎动物都具备这种神经装置的可能性。
