Brief visual oddball events evoke CSF flow in the spinal canal

The paper measures CSF flow in the spinal canal using fMRI and finds it correlates with BOLD activity decreases and is provoked by visual oddball stimuli.

ADRA2B genetic polymorphism modulates vagus nerve stimulation response

This study investigates how a genetic polymorphism in ADRA2B affects responses to vagus nerve stimulation, finding it influences pupillary responses and cortical activity alignment with noradrenergic projections.

Pupil size and pupil change correlate with distinct cortical neurochemical systems across the adult lifespan

The paper shows that pupil size and its change correlate with different neurochemical systems in the brain across adult ages, with pupil change specifically linked to norepinephrine transporter density.

Vagal nerve stimulation alters task-evoked pupillary responses in older adults but not younger adults in a single-blind sham-controlled crossover trial

This study investigates age-related differences in pupillary responses to vagal nerve stimulation (VNS) using a visual oddball task in older and younger adults.

Locus coeruleus neuromelanin accumulation and dissipation across the lifespan

This study examines neuromelanin accumulation and dissipation in the locus coeruleus across aging, finding increased intensity until age 60 followed by a decline, with cognitive associations in older adults.

Attention-dependent coupling with forebrain and brainstem neuromodulatory nuclei changes across the lifespan

The paper examines how attention-related functional connectivity between subcortical neuromodulatory nuclei and cortical regions changes across the lifespan, revealing age-related shifts in network architecture.
