We explored the macro-scale neurovascular coupling via the spectral correspondence of concurrent EEG-fMRI signals in a resting-state condition and a eye-open-eye-close (EOEC) task. By decomposing time-frequency maps for both signals, we revealed the EEG-fMRI spectral coupling through the temporal correlations at different frequency bands in the resting state, as compared with those in the EOEC task.

睁眼闭眼任务和静息状态下的神经血管耦合：并发脑电图和功能磁共振成像之间的频谱对应关系

我们通过静息状态条件和睁眼闭眼（EOEC）任务中并发 EEG-fMRI 信号的光谱对应关系探索了宏观神经血管耦合。通过分解两个信号的时频图，与 EOEC 任务中的情况相比，我们通过静息状态下不同频段的时间相关性揭示了 EEG-fMRI 频谱耦合。[显示省略]
