Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

Use of Z‐Scores and Percentages to Assess Structural Brain MRI Findings in Patients With Schizophrenia

International Journal of Methods in Psychiatric Research, Volume 35, Issue 2, June 2026.
ABSTRACT Objectives Schizophrenia is associated with structural brain abnormalities, although findings have been inconsistent. This study aimed to investigate global and regional volumetric measures in patients with schizophrenia using an automated volumetric analysis tool.

Dimensional association between ADHD traits and gray matter volume in young adults: A voxel‐based morphometry study

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
This study examined the association between attention‐deficit/hyperactivity disorder (ADHD) traits and gray matter volume (GMV) in 534 healthy young adults. Higher Hyperactivity/Restlessness scores were associated with greater GMV in the right dorsolateral prefrontal cortex (DLPFC), a region implicated in executive control and behavioral regulation. No

Sleep enhances gamma oscillations in the seizure onset zone and broadband activity in the irritative zone of focal cortical dysplasia

Epilepsia Open, Volume 11, Issue 2, Page 435-451, April 2026.
Abstract Objective Focal cortical dysplasia (FCD) is a leading cause of drug‐resistant epilepsy and is associated with sleep‐related seizures, yet the underlying electrophysiological mechanisms during different brain states remain poorly understood. We investigated whether fast oscillations (FOs) within the seizure onset zone (SOZ) and irritative zone (

Evaluation of Brain Microstructural Alterations in Preschool Autism Spectrum Disorder: A Voxel‐Wise Multimodal MRI Study

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 1053-1066, April 2026.
ABSTRACT Background Autism Spectrum Disorder (ASD) presents with early neurodevelopmental alterations in preschool children, yet comprehensive characterization using multimodal quantitative MRI remains limited in this age group. Purpose To investigate voxel‐wise brain microstructural differences in preschool ASD through integrated analysis of cerebral ...

Revealing The True Mechanical Behavior Of Porous Tendon Scaffolds Via In Situ Morphometry

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Strain‐dependent morphology is measured in electrospun porous polymeric tendon/ligament scaffolds. This dependence significantly affects the scaffolds’ mechanical characteristics. Analysis of both morphological and mechanical changes helps to correlate them. More physiological characteristics are obtained by considering morphological changes.
