在本研究中，我们调查的神经元的视觉反应，内皮层，arcopallium，巢皮层，和海马的鸽子。研究人员向鸽子提供了12种不同的刺激，其中包括三种鸽子的刺激（鸽子面部的肖像，鸽子面部的侧面视图和整只鸽子的照片）。共记录了53个细胞来自内皮层，65个来自arcopallium，32个来自巢皮层，67个来自海马。虽然一些神经元对某些颜色和形状有选择性，但没有神经元只对三种鸽子刺激有选择性。这一发现与以前的研究形成鲜明对比，在一系列哺乳动物中证明了对同种图像的选择性射击。而不是反映鸽子中没有这些细胞，我们认为我们的研究结果可能反映了鸽子在理解3D刺激的2D表示之间的对应关系的困难。
In the present study we investigate the visual responsiveness of neurons in the entopallium, arcopallium, nidopallium, and hippocampus of pigeons. Pigeons were presented with 12 different stimuli, including three stimuli of a pigeon (a portrait of a pigeon's face, a profile view of a pigeon's face, and a picture of a whole pigeon). A total of 53 cells were recorded from the entopallium, 65 from the arcopallium, 32 from the nidopallium, and 67 from the hippocampus. Although a number of neurons were selective for certain colours and shapes, no neurons were solely selective for the three pigeon stimuli. This finding contrasts with previous studies across a range of mammals demonstrating selective firing to images of conspecifics. Rather than reflecting an absence of these cells in pigeons, we argue our findings may reflect the difficulty pigeons have in understanding the correspondence between 2D representations of 3D stimuli.
