摘要
本研究旨在利用独立成分分析(ICA)方法研究飞行学员静息状态脑网络的功能变化。共招募飞行学员33名,普通大学生33名。静息状态fMRI数据采集采用3.0 T MRI扫描仪。采用ICA提取静息状态脑网络成分,并进行统计分析。在ICA过程中发现了14个生理上独立的成分,并将其分为9个网络。飞行学员腹侧注意网络右侧肌钙裂的激活显著增加(FWE校正,P < 0.05)。飞行学员差异脑区兴趣区值与伯格卡分类测验正确率呈显著正相关,与伯格卡分类测验持续误差呈显著负相关(P < 0.05)。飞行学员右肌钙裂的显著激活可能与飞行任务的高注意力要求有关。飞行学员表现出卓越的执行功能和注意力分配能力,这为专业活动引起的大脑适应性功能调整提供了证据。
Study on resting-state brain network alterations in flight trainees based on independent component analysis
This study aimed to investigate the functional alterations in the resting-state brain networks of flight trainees using the independent component analysis (ICA) method. A total of 33 flight trainees and 33 general college students were recruited. Resting-state fMRI data were collected using a 3.0 T MRI scanner. ICA was employed to extract resting-state brain network components, followed by statistical analyses. Fourteen physiologically independent components were identified during the ICA process and classified into nine networks. The flight trainees exhibited significantly increased activation in the right calcarine fissure within the ventral attention network (FWE corrected, P < 0.05). Moreover, the region of interest values of the differential brain region in flight trainees showed a significant positive correlation with the correct rate of the Berg Card Sorting Test (BCST) and a significant negative correlation with the BCST perseverative error (P < 0.05 for both). The significant activation of the right calcarine fissure of flight trainees may be associated with the high attentional demands of flight tasks. Flight trainees demonstrated superior executive function and attention allocation abilities, providing evidence of adaptive functional adjustments in the brain caused by professional activities.
