动物之间的社会互动可以在许多情况下发生，例如在觅食期间。我们对鸟类大脑中与社会互动相关的区域的了解仅限于由单一环境或感觉方式激活的区域。我们使用18F-氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）检查美国乌鸦（乌鸦brachyrhynchos）的大脑活动的条件下，与公共喂养。使用配对的方法，我们将乌鸦暴露于视觉刺激（食物的景象），音频刺激（觅食时同种发声的声音）或同时呈现的音频/视觉刺激，并将其与控制刺激（空阶段）的大脑活动进行比较。我们发现两个区域，带核的杏仁核（TnA）和内侧部分的尾巢皮质，表现出增加的活动，响应于多模态组合的刺激，但不响应于任何刺激时，提出单峰。我们还发现，显着增加的活动，在外侧隔和内侧巢皮质内的声音，只有和组合的音频/视觉刺激。我们没有发现任何差异的激活响应视觉刺激本身。我们将讨论这些区域如何参与多模态刺激的社会互动的背景下处理。
Social interaction among animals can occur under many contexts, such as during foraging. Our knowledge of the regions within an avian brain associated with social interaction is limited to the regions activated by a single context or sensory modality. We used 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) to examine American crow (Corvus brachyrhynchos) brain activity in response to conditions associated with communal feeding. Using a paired approach, we exposed crows to either a visual stimulus (the sight of food), an audio stimulus (the sound of conspecifics vocalizing while foraging) or both audio/visual stimuli presented simultaneously and compared to their brain activity in response to a control stimulus (an empty stage). We found two regions, the nucleus taenia of the amygdala (TnA) and a medial portion of the caudal nidopallium, that showed increased activity in response to the multimodal combination of stimuli but not in response to either stimulus when presented unimodally. We also found significantly increased activity in the lateral septum and medially within the nidopallium in response to both the audio-only and the combined audio/visual stimuli. We did not find any differences in activation in response to the visual stimulus by itself. We discuss how these regions may be involved in the processing of multimodal stimuli in the context of social interaction.
