前额皮质功能障碍通常与焦虑症有关,但其机制仍不清楚。接近-回避冲突任务已广泛用于动物研究中,以更好地了解前额皮质内神经活动的变化如何导致回避行为,而回避行为被认为在焦虑症的维持中发挥着重要作用。在本文中,我们首先回顾利用体内电生理学揭示啮齿动物神经活动变化与回避行为之间关系的研究。然后,我们回顾了最近的研究,这些研究利用光学和遗传技术来测试特定前额皮质回路和细胞类型对控制焦虑相关回避行为的独特贡献。这项新的工作揭示了接近-回避冲突期间的行为是由个体细胞类型、不同的神经通路和特定的振荡频率动态调节的。这些不同途径的整合,特别是通过兴奋性和抑制性神经元之间的相互作用介导的整合,为未来理解焦虑提供了令人兴奋的机会。
Dysfunction in the prefrontal cortex is commonly implicated in anxiety disorders, but the mechanisms remain unclear. Approach-avoidance conflict tasks have been extensively used in animal research to better understand how changes in neural activity within the prefrontal cortex contribute to avoidance behaviors, which are believed to play a major role in the maintenance of anxiety disorders. In this article, we first review studies utilizing in vivo electrophysiology to reveal the relationship between changes in neural activity and avoidance behavior in rodents. We then review recent studies that take advantage of optical and genetic techniques to test the unique contribution of specific prefrontal cortex circuits and cell types to the control of anxiety-related avoidance behaviors. This new body of work reveals that behavior during approach-avoidance conflict is dynamically modulated by individual cell types, distinct neural pathways, and specific oscillatory frequencies. The integration of these different pathways, particularly as mediated by interactions between excitatory and inhibitory neurons, represents an exciting opportunity for the future of understanding anxiety.
