Long-term relationships are essential for the psychological wellbeing of humans and many animals. Positive emotions and affective experiences (e.g., romantic or platonic love) seem to be closely related to the creation and maintenance of social bonds. When relationships are threatened or terminated, other emotions generally considered to be negative can arise (e.g., jealousy or loneliness). Because humans and animals share (to varying degrees) common evolutionary histories, researchers have attempted to explain the evolution of affect and emotion through the comparative approach. Now brain imaging techniques allow the comparison of the neurobiological substrates of affective states and emotion in human and animal brains using a common methodology. Here, we review brain imaging studies that feature emotions characterized by the context of social bonding. We compare imaging findings associated with affective and emotional states elicited by similar social situations between humans and animal models. We also highlight the role of key neurohormones (i.e., oxytocin, vasopressin, and dopamine) that jointly support the occurrence of socially contextualized emotions and affect across species. In doing so, we seek to explore and clarify if and how humans and animals might similarly experience social emotion and affect in the context of social relationships.
长期关系对人类和许多动物的心理健康至关重要。积极情绪和情感体验（如浪漫爱情或柏拉图式的爱）似乎与社会关系的建立和维持密切相关。当关系受到威胁或终止时，通常被认为是负面的其他情绪可能会出现（如嫉妒或孤独）。由于人类和动物（在不同程度上）有着共同的进化历史，研究人员试图通过比较方法来解释情感和情绪的进化。现在，脑成像技术允许使用一种通用方法来比较人类和动物大脑中情感状态和情绪的神经生物学基础。在这里，我们回顾了以社会关系背景为特征的情绪的脑成像研究。我们比较了人类和动物模型中由类似社会情境引发的情感和情绪状态相关的成像结果。我们还强调了关键神经激素（即催产素、加压素和多巴胺）的作用，它们共同支持跨物种的社会情境化情绪和情感的发生。通过这样做，我们试图探索和阐明人类和动物在社会关系背景下是否以及如何可能类似地体验社会情绪和情感。
