During the RW session, participants were allowed normal sleep; during SD, they remained awake for 24\u202fh; and in the NAP session, a two-hour nap was allowed during their night shift. Neurocognitive assessments and resting-state functional magnetic resonance imaging were conducted after SD and NAP sessions. Voxel-mirrored homotopic connectivity (VMHC) analysis was used to assess interhemispheric functional coordination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared with RW, SD led to a significant increase in VMHC, primarily involving the bilateral temporal, occipital, and parietal cortices, sensorimotor areas, middle and inferior frontal cortices, insula, subcortical regions, and cerebellum [family-wise error (FWE)-corrected\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05].
