项目摘要

Over the past few decades, research involving the neural control of breathing has centered on how the breathing rhythm is generated and how sensory systems detect internal and external changes to modulate the breathing pattern. While we have learned that the regulatory breathing rhythm originates in the medulla, we know little about the neural circuits by which breathing affects emotional state. The positive effects of controlled breathing on emotional state have been observed across many contexts and in the clinic. Using objective behavioral, physiological, and neuroanatomical parameters, we propose: i) to fully determine the neural pathways in mice from the preBötzinger Complex, the key site generating inspiratory rhythm in the medulla, to supramedullary regions, in particular to the locus coeruleus and its ascending projections, that effect and/or affect emotional state, and; ii) to establish the role of these projections from the preBötzinger Complex in mediating the effects of breathing on anxiety, fear and panic in mice. The proposed research has the potential to lead to more effective methods for treating debilitating negative emotional states

在过去的几十年里，涉及呼吸神经控制的研究集中在如何呼吸节律是如何产生的，以及感觉系统如何检测内部和外部的变化来调节呼吸节律呼吸模式。虽然我们知道调节呼吸节律起源于延髓，但我们对呼吸影响情绪状态的神经回路知之甚少。控制的积极影响在许多情况下和在诊所中都观察到了呼吸对情绪状态的影响。使用目标行为、生理和神经解剖学参数，我们建议：i) 充分确定神经小鼠中从前博辛格复合体（延髓中产生吸气节律的关键位点）到髓上区域，特别是蓝斑及其上升投影，影响和/或影响情绪状态； ii) 确定这些来自 preBötzinger Complex 的预测的作用调节呼吸对小鼠焦虑、恐惧和恐慌的影响。拟议的研究具有潜力找到更有效的方法来治疗使人衰弱的负面情绪状态
