Non-human animals tend to solve behavioral tasks using local information. Pigeons are particularly biased toward using the local features of stimuli to guide behavior in small-scale environments. When behavioral tasks are performed in large-scale environments, pigeons are much better global processors of information. The local and global strategies are mediated by two different fovea in the pigeon retina that are associated with the tectofugal and thalamofugal pathways. We discuss the neural mechanisms of pigeons' bias for local information within the tectofugal pathway, which terminates at an intermediate stage of extracting shape complexity. We also review the evidence suggesting that the thalamofugal pathway participates in global processing in pigeons and is primarily engaged in constructing a spatial representation of the environment in conjunction with the hippocampus.
非人类动物倾向于利用局部信息解决行为任务。鸽子在小规模环境中特别倾向于利用刺激的局部特征来指导行为。当在大规模环境中执行行为任务时，鸽子是更好的全局信息处理器。局部和全局策略由鸽子视网膜中的两个不同中央凹介导，它们与顶盖离心和丘脑离心通路相关。我们讨论了鸽子在顶盖离心通路中偏向局部信息的神经机制，该通路在提取形状复杂性的中间阶段终止。我们还回顾了证据，表明丘脑离心通路参与鸽子的全局处理，并且主要与海马体一起参与构建环境的空间表征。
