Objective: The authors examined differences in resting-state functional connectivity (rsFC) in the brain between nontreatment-seeking adults with alcohol use disorder (case group) and recreational drinkers without alcohol use disorder (control group) and explored behavioral and psychological mechanisms underlying these differences.
Methods: This case-control study included 140 adults (N=71 with alcohol use disorder and N=69 demographically matched control individuals) who completed a 9-minute resting-state functional MRI scan. About 45% were men, and the mean±SD age was 32.

Neuroimaging in rodents holds promise for advancing our understanding of the central nervous system (CNS) mechanisms that underlie chronic pain. Employing two established, but pathophysiologically distinct rodent models of chronic pain, the aim of the present study was to characterize chronic pain-related functional changes with resting-state functional magnetic resonance imaging (fMRI). In Experiment 1, we report findings from Lewis rats 3 weeks after Complete Freund's adjuvant (CFA) injection into the knee joint (n = 16) compared with the controls (n = 14).

The current study sought to explore the impact of a novel noninvasive treatment called transcranial photobiomodulation (PBM) on resting-state functional connectivity (rsFC) of the cerebellum in individuals with a history of repetitive head acceleration events (RHAEs). RHAEs are associated with cumulative neurological compromise, including chronic alterations in rsFC; however, few treatments have been investigated to mitigate these effects. A recent study by our team demonstrated that PBM treatment led to improvements in measures of balance and motor function in adults with RHAE exposure.

Background: Sexual dimorphism in human brain has garnered significant attention in neuroscience research. Although multiple investigations have examined sexual dimorphism in gray matter (GM) functional connectivity (FC), the research of white matter (WM) FC remains relatively limited.
Methods: Utilizing resting-state fMRI data from 569 healthy young adults, we investigated sexual dimorphism in the WM functional connectome.

Temporal lobe epilepsy (TLE) patients experience shifts between non-seizing and seizing brain states, but the structural networks underlying these transitions remain undefined and poorly characterized. We detected dynamic brain states in resting-state fMRI and constructed linked structural networks utilizing multi-shell diffusion-weighted MR data. Leveraging network control theory, we interrogated the structural data for all possible brain state transitions, identifying those requiring abnormal levels of transition energy (low or high) in TLE compared to matched healthy participants (n's = 25).
