通过鼻子呼吸与口腔呼吸对大脑连接有不同的影响. 鼻腔呼吸涉及更高阶网络,而口腔呼吸则专注于大脑干,揭示了一个新的呼吸引发的大脑振荡网络 (REBON).
科学领域:
- 神经科学是一个神经科学.
- 认知神经科学 认知神经科学
- 人类大脑成像技术
背景情况:
- 众所周知,呼吸可以节奏调节大脑活动.
- 鼻腔呼吸与口腔呼吸对频率特定的大规模神经连接的独特影响在人类中仍然未被探索.
研究的目的:
- 调查鼻腔和口腔呼吸模式如何调节功能性大脑连接.
- 在不同的呼吸模式中识别特定频率的大规模神经网络参与.
主要方法:
- 休息状态功能磁共振成像 (fMRI) 用于20名健康男性参与者.
- 分析的重点是0.1-0.2赫兹频段的血液氧化水平依赖 (BOLD) 波动.
- 使用了基于数据的ROI推断和基于种子的连接性 (SBC) 分析与非参数变量测试.
主要成果:
- 鼻腔呼吸显著激活了嗅觉区域,增加了更高阶网络的连接性 ( Salience,体感,默认模式,前端对称).
- 口腔呼吸显著激活了大脑干,增加了皮层下自主调节区域的连接性.
- 这两种模式都涉及到呼吸区域 (海马体,杏仁体,胰岛) 的稳定核心.
结论:
- 发现了一种新的呼吸引发的大脑振荡网络 (REBON),特定于0.1-0.2 Hz频段.
- REBON活动的特点是嗅觉区域 (鼻腔呼吸) 和大脑干 (口腔呼吸) 之间交替主导,具有稳定的边缘/接收内核.
- 研究结果表明,对认知功能,情绪调节和大脑网络完整性有潜在的治疗影响.

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
