We have used resting state fMRI to study the functional connectivity network in individuals with Shift Work Sleep Disorder (SWSD) and compared it to the connectivity networks of asymptomatic night shift workers (SWC) and daytime workers (NC). We used a framework in our analysis for segmenting the brain and finding the correlation between the fMRI signals in each segment pair. Our results show differences in the functional connectivity network between the NC and SWC groups however, the connectivity pattern of the SWC group is more correlated to the NC group than the SWSD group pattern which confirms previously reported results.
