Stress profoundly impacts quality of life and may lead to various diseases and conditions. Understanding the underlying physiological and neurological processes that take place during stress and meditation techniques may be critical for effectively treating stress-related diseases. The article examines a hypothetical physiological homeostatic response that compares and contrasts changes in central and peripheral oscillations during stress and meditation, and relates these to changes in the autonomic system and neurological activity. The authors discuss how cardiorespiratory synchronization, which occurs during the parasympathetic response and meditation, influences and modulates activity and oscillations of the brain and autonomic nervous system. Evidence is presented on how synchronization of cardiac and respiratory rates during meditation may lead to a homeostatic increase in cellular membrane potentials in neurons and other cells throughout the body. These potential membrane changes may underlie the reduced activity in the amygdala, and other cortical areas during meditation, and research examining these changes may foster better understanding of the restorative properties and health benefits of meditation.
压力对生活质量有深远影响，可能导致各种疾病和状况。了解压力和冥想技巧过程中发生的潜在生理和神经过程，对于有效治疗与压力相关的疾病可能至关重要。本文探讨了一种假设的生理稳态反应，该反应比较和对比了压力和冥想期间中枢和外周振荡的变化，并将这些变化与自主神经系统和神经活动的变化联系起来。作者讨论了在副交感神经反应和冥想期间发生的心肺同步如何影响和调节大脑和自主神经系统的活动及振荡。文中给出了证据，说明冥想期间心脏和呼吸频率的同步如何可能导致全身神经元和其他细胞的细胞膜电位稳态增加。这些潜在的膜变化可能是冥想期间杏仁核和其他皮质区域活动减少的基础，研究这些变化可能有助于更好地理解冥想的恢复特性和健康益处。
