杏仁核对情绪处理和动机行为至关重要。它在这些功能中的作用是由于它处理环境刺激的效价。杏仁核接收来自感觉丘脑和皮层区域的直接感觉输入，以整合来自环境的感觉信息，并产生厌恶和/或食欲结果。由于许多评论已经讨论了杏仁核的威胁处理和恐惧条件反射的作用，这篇评论将集中在杏仁核编码积极的效价和机制，使其能够区分刺激的积极和消极的效价。这些研究结果也延伸到考虑如何价编码人口在杏仁核有助于本地和远程电路，包括那些整合环境线索和积极的效价。了解杏仁核中价编码的复杂性是至关重要的，因为这些机制与各种疾病状态有关，包括焦虑症和物质使用障碍。
The amygdala is critical for emotional processing and motivated behavior. Its role in these functions is due to its processing of the valence of environmental stimuli. The amygdala receives direct sensory input from sensory thalamus and cortical regions to integrate sensory information from the environment with aversive and/or appetitive outcomes. As many reviews have discussed the amygdala’s role in threat processing and fear conditioning, this review will focus on how the amygdala encodes positive valence and the mechanisms that allow it to distinguish between stimuli of positive and negative valence. These findings are also extended to consider how valence encoding populations in the amygdala contribute to local and long-range circuits including those that integrate environmental cues and positive valence. Understanding the complexity of valence encoding in the amygdala is crucial as these mechanisms are implicated in a variety of disease states including anxiety disorders and substance use disorders.
