Background The neural mechanisms of sleep beliefs and attitudes in primary insomnia (PI)
patients at resting state remain unclear. The aim of this study was to investigate the features …

Study objective To prospectively explore the underlying regional homogeneity (ReHo) brain-
activity deficit in patients with chronic primary insomnia (PCPIs) and its relationship with …

Purpose The study aimed to explore the regional spontaneous activity changes in primary
insomnia (PI) patients. Materials and methods Based on the resting-state fMRI datasets …

Background Previous studies have demonstrated that obstructive sleep apnea (OSA) is
associated with abnormal brain structural deficits. However, little is known about the …

Subjective–objective discrepancy of sleep (SODS) might be related to the distorted
perception of sleep deficit and hypersensitivity to insomnia-related stimuli. We investigated …

Study Objectives: To explore the regional brain activities in patients with chronic primary
insomnia (PCPIs) and their sex differences. Methods: Forty-two PCPIs (27 females, 15 …

To identify altered inter-hemispheric communication between patients with primary insomnia
(PIs) and good sleepers (GSs), and their relationships with sleep and emotion-related …

Objective Investigating functional specialization is crucial for a complete understanding of
the neural mechanisms of primary insomnia (PI). Resting-state functional magnetic …

Background: Resting-state functional magnetic resonance imaging (fMRI) studies have
uncovered the disruptions of functional brain networks in primary insomnia (PI) patients …

Background: Recently, there have been many reports about abnormalities regarding
structural and functional brain connectivity of the patients with primary insomnia. However …
