Neural correlates of shift work in nurses: Alterations in cortical gyrification and functional connectivity
Brain surface folding and communication changes linked to shift work in nurses
AI simplified
Abstract
Night-shift nurses showed increased local gyrification index in the right superior temporal gyrus compared to day-shift nurses.
- Night-shift nurses reported poorer sleep quality and higher levels of anxiety and depression.
- Altered brain structure included increased local gyrification in the right superior temporal gyrus extending to the superior temporal sulcus.
- Functional connectivity changes were observed, with reduced connectivity between the superior temporal gyrus and posterior cerebellum.
- Increased connectivity between the superior temporal gyrus and precuneus/cuneus was associated with higher anxiety scores and poorer sleep quality.
- Higher local gyrification index correlated with poorer sleep quality among the pooled data.
