This study examines the effects of one-night partial sleep deprivation on perivascular space volume fraction using the Stockholm Sleepy Brain Study, finding no significant overall association but some interactions that did not survive multiple comparisons.

This study investigates how sleep restriction affects emotional regulation using fMRI, finding increased prefrontal cortex activity in young participants but no brain activation changes in either age group.

This study examines how partial sleep deprivation affects intrinsic brain connectivity in young and older adults using fMRI and finds increased global signal variability but no significant changes in resting state networks.

This study conducts a meta-analysis of IL-6 levels across the day, finding a morning trough rather than evening peak, suggesting diurnal variation should be considered in IL-6 research.
