Eyes‐Closed Resting‐State fMRI After Sleep Deprivation: A Vigilance‐Sensitive Window

Key Points

• This research aims to explore how sleep deprivation affects brain activity during resting-state fMRI scans, particularly focusing on vigilance levels.
• Participants underwent eyes-closed resting-state fMRI after periods of sleep deprivation.
• Vigilance levels were assessed through standardized cognitive tasks.
• Data analysis focused on brain activity patterns in relation to sleep loss.
• Resting-state fMRI showed significant changes in brain activity linked to decreased vigilance after sleep deprivation.
• Specific brain regions exhibited altered connectivity, correlating with cognitive performance; specific metrics were not provided.
