Sleep deprivation (SD) is associated with a significantly reduced task-related decrease in functional connectivity, which, in turn, is significantly associated with changes in cognitive performance.
Why this matters
Up to 39% of adults aged 18–65 years suffer from SD, which has a significant negative impact on their cognitive function.
Neuroimaging studies have shown decreased local and global neuronal activity associated with SD, but the mechanisms involved are not fully understood.
This is the first published study that used the functional near-infrared spectroscopy (fNIRS) to assess the effect of SD on resting-state and task-related functional connectivity of the frontal lobe.
