图背后的故事
背景:白噪声因其对心理和生理状态的潜在作用(尤其是促进放松)而受到广泛关注。前额叶皮层是负责高级认知功能与情绪调节的关键脑区,其对外界刺激的反应可能影响个体的身心健康。尽管已有研究考察白噪声的镇静作用,但针对其影响前额叶皮层活动的系统研究仍然缺乏。本研究旨在探讨白噪声对前额叶皮层的镇静作用及相关生理机制。方法:共招募 103 名健康大学生,随机分为四组(炉火 n=24、风 n=27、雨 n=27、雪 n=25),每组暴露于对应白噪声 3 分钟。采用功能近红外光谱(fNIRS)评估脑兴奋性变化,同时测量生命体征与面部表情的变化。结果:fNIRS 数据经配对样本 t 检验分析:在风组与雪组中,白噪声可有效降低相关脑区的皮层兴奋性;兴奋性降低的区域集中在额极部的额前皮层与 Broca 区三角部,两个区域的氧合血红蛋白浓度分别从 −0.159 降至 −0.107 µmol/L、从 −0.139 降至 −0.096 µmol/L,二者均参与放松与镇静调节。结论:白噪声可降低前额叶皮层的兴奋性并发挥镇静作用,有助于加深对白噪声参与神经调控方式的理解。

文章摘要(中文译文 · 原文照录)
中文译文 背景:白噪声因其对心理与生理状态的潜在影响而受到广泛关注,尤其在促进放松方面。前额叶皮质是负责高级认知功能与情绪调节的关键脑区,可能通过对外界刺激的反应影响个体身心健康。既往研究已考察白噪声的镇静效果,但对其如何具体影响前额叶皮质活动的系统研究仍然缺乏。本研究旨在探索白噪声对前额叶皮质的镇静作用,阐明其相关生理机制。方法:共招募103名健康成年大学生,随机分为四组(篝火声 n = 24;风声 n = 27;雨声 n = 27;雪声 n = 25),各组暴露于相应白噪声3分钟;采用功能近红外光谱(fNIRS)评估脑兴奋性变化,并测量生命体征与面部表情变化。结果:fNIRS 数据采用配对样本 t 检验分析;风声组与雪声组中,白噪声可有效降低相关脑区的皮质兴奋性,兴奋性降低的区域集中在前额叶皮质与布罗卡区前额极三角部,两区氧合血红蛋白浓度分别由 −0.159 降至 −0.107 µmol/L、由 −0.139 降至 −0.096 µmol/L,均参与放松与镇静调节。结论:白噪声可降低前额叶皮质兴奋性并发挥镇静作用,有助于深化对白噪声参与神经调控机制的理解。
Background: White noise has attracted widespread attention due to its potential effects on psychological and physiological states, particularly in promoting relaxation. The prefrontal cortex, a critical region of the brain responsible for higher cognitive functions and emotional regulation, may influence an individual's mental and physical health through its responses to external stimuli. Although previous research has investigated the calming effects of white noise, systematic studies on its specific impact on prefrontal cortex activity are still lacking. This study aims to explore the calming effects of white noise on the prefrontal cortex to elucidate its associated physiological mechanisms. Methods: In total, 103 healthy adult college students were recruited and randomly divided into four groups (fire, n = 24; wind, n = 27; rain, n = 27; and snow, n = 25), with each group exposed to the corresponding white noise for 3 min. Functional near-infrared spectroscopy (fNIRS) was used to evaluate excitability changes in the brain and changes in life signs and facial expressions were also measured. Results: The data of fNIRS were analyzed by paired sample t-test; in the wind group and the snow group, we found that the white noise can be effectively decreased the cortical excitability of related brain areas. The areas of reduced excitability were concentrated in the prefrontal cortex and pars triangularis of Broca's frontopolar area, while the concentration of oxyhemoglobin in these two area decreased from −0.159 to −0.107 µmol/L and from −0.139 to −0.096 µmol/L, respectively, both areas involved in relaxing and sedative modulation. Conclusion: White noise can reduce the excitability of the prefrontal cortex and play a sedative effect. It may strengthen our understanding of how white noise is involved in neural modulation.
