Background

Heightened body awareness (BA) is conducive for increasing understanding of bodily state and improves individuals' health and well-being. Although there has been cumulative research concentrating on the self-perceived tendency to focus on negatively valenced interoceptive sensations, the specific structural and functional neural patterns underlying BA and their role in the relationship between BA and individual well-being remain unclear.

Methods

Voxel-based morphometry and whole brain functional connectivity analyses were conducted to examine the structural and functional neural patterns, respectively, in 686 healthy subjects. BA and subjective well-being were assessed using questionnaires.

Results

BA was inversely related to gray matter volume of the right inferior frontal gyrus, opercular part (IFGoperc). Higher BA was correlated with enhanced IFGoperc-precuneus and IFGoperc-anterior supramarginal gyrus connectivities, and with decreased IFGoperc-lateral occipital cortex and IFGoperc-medial frontal cortex connectivities. The inferior frontal gyrus, triangular part (in the fronto-parietal task control network) acted as the hub that linked the sensory/somatomotor network, the default mode network, and the dorsal and ventral attention network. The IFGoperc-precuneus connectivity moderated the association between BA and subjective well-being.

Limitations

We were unable to rank all the networks by their relative importance, because the absolute weighted value in each module was not calculated.

Conclusion

Our findings demonstrated that BA was reflected by specific neural patterns mainly involved in cognitive-affective control, attentional and self-referential processing, as well as multisensory integration, which could offer some references for current therapies (e.g., mindfulness, yoga training) that are dedicated to solving health problems and improving individual well-being.

了解你的感受：支持自适应身体意识的基于额下回的结构和功能神经模式

背景

提高身体意识 (BA) 有助于增加对身体状态的了解，并改善个人的健康和福祉。尽管有积累的研究集中在自我感知的倾向上，集中在负价内感受上，但 BA 背后的特定结构和功能神经模式及其在 BA 与个人幸福感之间的关系中的作用仍不清楚。

方法

进行了基于体素的形态测量和全脑功能连接分析，以分别检查 686 名健康受试者的结构和功能神经模式。使用问卷评估 BA 和主观幸福感。

结果

BA 与右侧额下回、鳃盖部分 (IFGoperc) 的灰质体积呈负相关。较高的 BA 与增强的 IFGoperc-楔前叶和 IFGoperc-前缘上回连接性增强，以及 IFGoperc-枕外侧皮质和 IFGoperc-内侧额叶皮质连接性降低相关。额下回三角形部分（在额顶任务控​​制网络中）充当连接感觉/躯体运动网络、默认模式网络以及背侧和腹侧注意网络的枢纽。IFGoperc-precuneus 连接调节了 BA 与主观幸福感之间的关联。

限制

我们无法根据网络的相对重要性对所有网络进行排名，因为没有计算每个模块中的绝对加权值。

结论

我们的研究结果表明，BA 反映在主要涉及认知情感控制、注意力和自我参照处理以及多感觉整合的特定神经模式上，这可以为当前的治疗（例如，正念、瑜伽训练）提供一些参考。致力于解决健康问题和改善个人福祉。
