| 内容記述 | Sleep quality is known to influence brain function, yet the impact of normal day-to-day sleep variation on resting-state functional connectivity (rsfMRI) remains underexplored. This study investigated whether everyday fluctuations in sleep quality affect connectivity within and between the default mode network (DMN) and salience network (SN). Fourteen healthy female subjects participated in two sets of tests that included sleep assessments and MRI scans across two consecutive days. Sleep quality was objectively measured using a portable EEG monitor in the participant's home environment. Prior sleep quality affected connectivity between the DMN and SN, and within the SN. The wake after sleep onset (WASO) index was found to have the strongest relationship with the connectivity between the DMN and SN. The SpD index was also significantly related to the connectivity within the SN. Subjects that had large changes in connectivity tended to have substantial changes in WASO between the two measurements. In contrast, even though there may have been a substantial change in connectivity for a particular subject, the accompanying change in SpD was relatively small. The results suggest that the WASO index is correlated to the DMN-SN interconnectivity, with the observed alteration in connectivity potentially arising from day-to-day variations in the index. Connectivity associated with the SpD index was observed within the SN, and in contrast to the WASO-related findings, these changes are more likely to reflect individual traits rather than daily fluctuations. | |||||||
