报告简介:
Resting-state fMRI (R-fMRI), without relying on any specific task, can detect spontaneous or intrinsic brain activity, which may reflect individuals’ chronic characteristics. Given this,R-fMRI is a potential sensitive technique to studying brain functional characters that relate to stable individual traits and brain disorders. In this talk, we will introduce two studies that apply R-fMRI to above question. Regarding stable individual trait, we examined stable associations between brain regions and loneliness based on amplitudes of low-frequency fluctuation (ALFF) across the whole brain. We found that loneliness was positively related to ALFF value within the inferior temporal gyrus (ITG). As for brain disorders, we investigated the potential biomarker of hand-motor recovery after stroke based on whole-brain functional connectivity (FC) seeded from supplementary motor area (SMA). We found significant group difference (good recovered patients vs. good recovered patients) in FC to several brain regions (e.g., superior temporal cortex), suggesting the role of the FC in predicting hand-motor recovery.
