In this preliminary study, researchers attempted to determine the relationship between sleep and quasi-periodic pattern strength. Three participants wore actigraphy watches for three nights prior to a resting-state functional MRI (rs-fMRI) scan. Actigraphy data was analyzed using the Cole Kripke analysis method. Functional connectivity was analyzed for quasi-periodic patterns (QPPs) between the default mode network (DMN) and the task-positive network (TPN). Due to errors involving preprocessing of rs-fMRI data, proper QPP analyses were unable to be conducted as the QPP template was abnormal. Further analysis of the data collected in the future will yield more conclusive results.
