In a recent study published in the journal Translational Psychiatry , researchers investigated the impacts of full-night-, early-night deprivation-, and late-night deprivation sleep on whole-brain connectivity. They utilized connectome-based predictive modeling (CPM) with data from the Somte polysomnographic (PSG) mobile recording system, including electroencephalography (EEG), electrooculography (EOG), and electromyography (EMG) recordings, concurrently collected from a cohort of 113 right-handed adult volunteers from universities in Beijing. Study findings elucidated that the rapid eye movement (REM) sleep stage was closely associated with connections within and between the default mode network (DMN), the cingulo-opercular network (CON), and visual and auditory networks.
They further revealed that the thalamus played a central role in the REM connectome and acted as a relay station for sensory information during REM. While not the first to establish a relationship between REM sleep loss and DMN connectivity, this study identified late-night sleep loss as having the most profound effect on the latter, which in turn may exacerbate the risk and intensity of psychiatric disorders.
