Abnormal Local Brain Activity in SCA3 Patients with Cognitive Impairment: A Resting-State Functional MRI Study

Cerebellar Alteration in Resting-State Functional Connectivity Among Kratom (Mitragyna speciosa) Users: Insights from Functional MRI.

Due to the psychotropic properties of kratom (Mitragyna speciosa), further studies are needed to measure its neurobiological impacts. This exploratory study employed resting-state functional magnetic resonance imaging (rs-fMRI) to examine alterations in brain activity and functional connectivity (FC) among kratom users...

Prefrontal Neurovascular Coupling Abnormalities Associated With Cognitive Performance in Multiple Sclerosis

ABSTRACT Background Cognitive impairment is a prevalent and debilitating feature in multiple sclerosis (MS), yet its pathophysiology remains incompletely understood. Dysfunction of the neurovascular unit (NVU) and impaired neurovascular coupling (NVC) may be related to cognitive performance in MS, but this pathway rema...

Spatial correspondence between altered brain function and normative neurotransmitter density maps in Type 1 diabetes mellitus.

Abnormal coordination of executive control network and default mode network in cognitive impairment after deep nuclei intracerebral hemorrhage

Modulating FC between these hub brain regions (R-DLPFC and PCC) may provide new therapeutic strategies for cognitive recovery after DNICH and abnormal coordination of intra-network and inter-network FC of ECN and DMN may represent a shared neural mechanism of cognitive impairment after DNICH.

Substantia nigra iron-related alterations, white matter disruption, and functional network dysconnectivity in temporal lobe epilepsy: a multimodal neuroimaging study

The authors' multimodal findings suggest subregion- and laterality-specific alterations in the SN of patients with TLE, with patterns differing between RTLE and LTLE.

Reduced amplitude of low frequency fluctuation in the sensorimotor cortex in early psychosis: association with motor dexterity and hyperconnectivity

Previous studies have demonstrated widespread regional abnormalities in blood oxygen level-dependent (BOLD) amplitude of low frequency fluctuation (ALFF) in psychotic disorders. How regional ALFF is related to functional connectivity and behavior in psychotic illness, however, is poorly understood. Here we examined v...
