BMJ:有趣!经常庆祝圣诞节大脑中会出现“圣诞精神网络”

2015-12-17 MedSci MedSci原创

本研究旨在检测和定位人类大脑中的圣诞精神。采用单盲、跨文化组设计,使用功能性磁共振成像(fMRI)进行探究。

本研究旨在检测和定位人类大脑中的圣诞精神。采用单盲、跨文化组设计,使用功能性磁共振成像(fMRI)进行探究。

研究共纳入了参加10名来自哥本哈根的经常庆祝圣诞节的健康参与者,以及10名在同一地区生活但是并没有庆祝圣诞节传统的健康参与者。

主要结果测量为有庆祝圣诞节传统的健康参与者在接受圣诞主题所造成的视觉刺激时大脑中被激活的区域。

参与者交叉观看一系列与圣诞节主题相关的图像以及包含类似特性但是并无圣诞节象征的图像,优化脑功能扫描以检测机体的血氧水平依赖(BOLD)的变化情况。扫描后,参与者完成一份关于其圣诞传统以及圣诞传统与圣诞节关系的调查问卷。对“圣诞节传统”及“无圣诞节传统”的参与者扫描的脑激活图进行分析。随后,计算两组间的差异以确定大脑中圣诞节相关的特定的脑激活区域。

结果发现,与无圣诞节传统及处于中立状态的参与者相比,庆祝圣诞的参与者其大脑激活后感觉运动皮层、运动前区和初级运动皮层以及顶叶的BOLD显著增加。这些脑区与机体的精神、躯体感觉及其他许多功能的面部表情识别有关。

总而言之,该研究发现人脑中存在一个“圣诞精神网络”,涉及了几个大脑皮质区。对于有庆祝圣诞传统的人们在庆祝圣诞时,这个网络可被激活,而对于无圣诞传统和处于中立状态的人来说则不会。仍有必要行进一步的研究,以了解该网络和大脑中其他潜在的假日回路。虽然此研究结果很有趣,但还应该谨慎解释这些研究结果。
