Individuals with high heart rate variability tend to have better emotional well-being than those with low heart rate variability, but the mechanisms of this association are not yet clear. In this paper, we propose the novel hypothesis that by inducing oscillatory activity in the brain, high amplitude oscillations in heart rate enhance functional connectivity in brain networks associated with emotion regulation. Recent studies using daily biofeedback sessions to increase the amplitude of heart rate oscillations suggest that high amplitude physiological oscillations have a causal impact on emotional well-being. Because blood flow timing helps determine brain network structure and function, slow oscillations in heart rate have the potential to strengthen brain network dynamics, especially in medial prefrontal regulatory regions that are particularly sensitive to physiological oscillations.
心率变异性高的个体往往比心率变异性低的个体具有更好的情绪健康状况，但这种关联的机制尚不清楚。在本文中，我们提出了一个新的假设，即通过诱导大脑中的振荡活动，高振幅的心率振荡增强了与情绪调节相关的脑网络中的功能连接。最近使用每日生物反馈训练来增加心率振荡幅度的研究表明，高振幅的生理振荡对情绪健康有因果影响。由于血流时间有助于确定脑网络的结构和功能，心率的缓慢振荡有可能加强脑网络动力学，特别是在对生理振荡特别敏感的内侧前额叶调节区域。
