  • Frontal_Sup_Medial_R = right medial superior frontal area; ParaHippocampal_R = right parahippocampal area; Parietal_Sup_L = left superior parietal area; PSG = polysomnography; Rectus_L = left rectus; Temporal_Mid_R = right middle temporal area; Temporal_Pole_Mid_L = left middle temporal pole; Temporal_Pole_Mid_R = right middle temporal pole.

  • We performed the partial correlation analysis between sleep efficiency from PSG and thalamocortical connectivity after controlling for age, sex and educational level.
