社会动机和奖励是动态且灵活的，可以在不同环境中自适应地变化，以满足不断变化的社会需求。当在季节性繁殖鸣禽中考虑季节性环境时，这一点尤为明显，因为它们从繁殖季节期间的性动机和奖励时期循环到繁殖季节之外的极端群居时期，此时非性社会互动获得奖励价值，促使鸟类形成鸟群。在这里，我们回顾了证据，证明内侧视前区（mPOA）在季节性适当的行为调整中发挥着关键的综合作用，mPOA中多巴胺活性的季节性变化调整了社会动机，阿片类药物活性的变化改变了社会奖励。实验表明，类固醇激素浓度的剧烈季节性波动会改变 mPOA 中阿片类药物和多巴胺相关蛋白和基因的表达模式，从而改变社会动机和奖励，以满足社会需求的季节性变化。这些关于鸟鸣和季节性的研究为社会动机和奖励的适应性变化背后的神经和内分泌机制提供了新的见解，并强调了 mPOA 在非生殖环境中重要社会行为中未被充分认识的、进化上保守的作用。
Social motivation and reward are dynamic and flexible, shifting adaptively across contexts to meet changing social demands. This is exceptionally apparent when seasonal contexts are considered in seasonally breeding songbirds as they cycle from periods of sexual motivation and reward during the breeding season to periods of extreme gregariousness outside the breeding season when non-sexual social interactions gain reward value, motivating birds to form flocks. Here we review evidence demonstrating a key integrative role for the medial preoptic area (mPOA) in the seasonally-appropriate adjustment of behaviors, with seasonal changes in dopamine activity in mPOA adjusting social motivation and changes in opioid activity modifying social reward. Experiments demonstrate that dramatic seasonal fluctuations in steroid hormone concentrations alter patterns of opioid- and dopamine-related protein and gene expression in mPOA to modify social motivation and reward to meet seasonal changes in social demands. These studies of birdsong and seasonality provide new insights into neural and endocrine mechanisms underlying adaptive changes in social motivation and reward and highlight an underappreciated, evolutionarily conserved role for the mPOA in important social behaviors in non-reproductive contexts.
