Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

The effects of peripheral and central high insulin on brain insulin signaling and amyloid-β in young and old APP/PS1 mice [PDF]

open access: yes
Hyperinsulinemia is a risk factor for late-onset Alzheimer's disease (AD). In vitro experiments describe potential connections between insulin, insulin signaling, and amyloid-β (Aβ), but in vivo experiments are needed to validate these relationships ...

Decrease of excessive daytime sleepiness after shunt treatment for normal pressure hydrocephalus

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleepiness and apathy are often reported in patients with normal pressure hydrocephalus. However, research on outcomes after shunt surgery has mainly focused on the classical triad symptoms, that is, gait, cognition, and bladder dysfunction. This study aimed to describe the effects of shunt treatment on excessive daytime sleepiness and whether ...

40 Hz light flickering facilitates the glymphatic flow via adenosine signaling in mice

open access: yesCell Discovery
The glymphatic-lymphatic system is increasingly recognized as fundamental for the homeostasis of the brain milieu since it defines cerebral spinal fluid flow in the brain parenchyma and eliminates metabolic waste.

Glymphatic system dysfunction in pediatric tourette syndrome Neuroimaging evidence from MRI metrics.

open access: yesJournal of Psychiatric Research
BACKGROUND AND OBJECTIVES The glymphatic system, vital for brain waste clearance, is implicated in neurodevelopmental diseases, but its role in pediatric Tourette syndrome (TS) is not well understood.

Overnight Dynamics of Ventricular Cerebrospinal Fluid Amyloid‐Beta, Lactate and Hypocretin in Patients With Hydrocephalus: A Pilot Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT This pilot observational study evaluated whether frequent overnight sampling of ventricular cerebrospinal fluid could clarify how sleep, hypocretin and lactate relate to amyloid‐β42 dynamics in adults with hydrocephalus. Seven participants underwent hourly ventricular cerebrospinal fluid sampling from early evening to late morning during ...

The role of the lymphatic system in cholesterol transport [PDF]

open access: yes
Reverse cholesterol transport (RCT) is the pathway for removal of peripheral tissue cholesterol and involves transport of cholesterol back to liver for excretion, starting from cellular cholesterol efflux facilitated by lipid-free apolipoprotein A1 ...

An Electroencephalographic Study of Sleep Spindle and Infraslow Oscillation in Children With Autism Spectrum Disorder

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT We investigated whether sleep microstructures show spatial differences in young children with autism compared with typically developing peers. 32‐channel electroencephalography (EEG) during natural sleep after 5–6 h of partial sleep deprivation was recorded from 53 children (26 with autism, 27 typically developing; 1.1–5.1 years).

Is sleep disruption a risk factor for Alzheimer’s disease? [PDF]

open access: yes
Sleep disturbances are routinely encountered in Alzheimer’s disease (AD) and affect about 25–40% of patients in the mild-to-moderate stages of the disease. In many, sleep pathology may represent a symptom of the underlying neurodegeneration.
