摘要:

颂钵作为一种古老的声音疗愈方式,经手工凿击可发出低频声音,并产生可被感知的谐音和振动。近年来有研究发现,颂钵可缓解压力以及抗焦虑,但其作用机制尚不明确。实验首先构建通过慢性应激束缚压力和睡眠剥夺构建了焦虑样行为小鼠模型,然后以颂钵垫模拟颂钵的声音和振动。结果发现,与人类不同,颂钵的谐音联合振动并不能改善小鼠的焦虑样行为,而单独的振动成分可改善小鼠的焦虑样行为。此外,颂钵振动可增加焦虑小鼠躯体感觉皮质和前额叶皮质中N-甲基-D-天冬氨酸受体1水平,并降低γ-氨基丁酸A受体α1亚型水平,并降低前额叶皮质中CaMKII水平,还可增加感觉皮质和前额叶皮质中γ-氨基丁酸能小白蛋白中间神经元数量。同时电生理测试显示,颂钵的振动能显著降低应激束缚压力和睡眠剥夺所致内侧前额叶皮质低频gamma振荡峰值频率的异常。由此说明,颂钵振动可通过减轻改善躯体感觉皮质和内侧前额叶皮质中的异常的分子和电生理活动而减轻焦虑样行为。

Abstract: Tibetan singing bowls emit low-frequency sounds and produce perceptible harmonic tones and vibrations through manual tapping. The sounds the singing bowls produce have been shown to enhance relaxation and reduce anxiety. However, the underlying mechanism remains unclear. In this study, we used chronic restraint stress or sleep deprivation to establish mouse models of anxiety that exhibit anxiety-like behaviors. We then supplied treatment with singing bowls in a bottomless cage placed on the top of a cushion. We found that unlike in humans, the combination of harmonic tones and vibrations did not improve anxiety-like behaviors in mice, while individual vibration components did. Additionally, the vibration of singing bowls increased the level of N-methyl-D-aspartate receptor 1 in the somatosensory cortex and prefrontal cortex of the mice, decreased the level of γ-aminobutyric acid A (GABA) receptor α 1 subtype, reduced the level of CaMKII in the prefrontal cortex, and increased the number of GABAergic interneurons. At the same time, electrophysiological tests showed that the vibration of singing bowls significantly reduced the abnormal low-frequency gamma oscillation peak frequency in the medial prefrontal cortex caused by stress restraint pressure and sleep deprivation. Results from this study indicate that the vibration of singing bowls can alleviate anxiety-like behaviors by reducing abnormal molecular and electrophysiological events in somatosensory and medial prefrontal cortex.
