Global brain activity links subcortical degeneration to cortical tau progressively across Braak regions over early Alzheimer disease stages

The paper links subcortical degeneration to cortical tau pathology in early Alzheimer's disease stages using global brain activity and ADNI cohort data.

Sleep deprivation exhibits age-dependent effect on infra-slow global brain activity

This study shows sleep deprivation increases global brain activity and its link to CSF flow, but this effect weakens with age, potentially increasing dementia risk.

Intrinsic forebrain arousal dynamics governs sensory stimulus encoding

This study shows that intrinsic forebrain arousal dynamics during passive viewing influence visual stimulus encoding efficiency in the visual cortex.

Sex-specific age-related changes in glymphatic function assessed by resting-state functional magnetic resonance imaging

The paper assesses sex-specific age-related changes in glymphatic function using resting-state fMRI in healthy aging participants, finding a decline after age 55, especially in females.

An orderly sequence of autonomic and neural events at transient arousal changes

The paper investigates co-variation between neural and autonomic signals during arousal states using rsfMRI, EEG, and autonomic indicators, finding combined contributions to fMRI signals.

Self-generated brain-wide spiking cascades govern replay dynamics in the hippocampus

The paper investigates how brain-wide spiking cascades during rest relate to hippocampal replay sequences in mice, finding that replay events are linked to specific types of cascades.

Early β-amyloid accumulation and hypoconnectivity in the default mode network are related to its disengagement from global brain activity

This study links early β-amyloid accumulation in the default mode network to reduced resting-state brain activity and glymphatic function in Alzheimer's disease.

Single neuron firing cascades underlie global spontaneous brain events

The paper identifies large-scale neuronal firing cascades in the mouse brain during rest, showing they are synchronized with global events and linked to arousal and sensory processing.

Decoupling of global brain activity and cerebrospinal fluid flow in Parkinson's cognitive decline

This study finds that reduced coupling between global brain activity and cerebrospinal fluid flow is associated with cognitive impairment in Parkinson's patients.

Brain activity fluctuations propagate as waves traversing the cortical hierarchy

This study identifies directionally constrained activity waves in human and monkey brain data that align with cortical hierarchy and subcortical structures.

Neuroimaging contrast across the cortical hierarchy is the feature maximally linked to behavior and demographics

The paper identifies a cortical hierarchy contrast in brain structure and function that correlates with behavioral and demographic traits.

Transient arousal modulations contribute to resting-state functional connectivity changes associated with head motion parameters

The paper investigates how transient arousal modulations contribute to resting-state fMRI connectivity changes linked to head motion parameters.
