Dependence of the Extra‐Cellular Diffusion Coefficient on the Fractions of Neurites and Cell Bodies in Gray Matter

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2426-2439, November 2026.
Purpose The dependence of the long‐time (tortuosity) limit of the extra‐cellular diffusivity on the intra‐cellular volume fraction is of fundamental importance for microstructure modeling. While such dependencies have been explored for the white matter, the tortuosity limit in gray matter is unknown due to complex cell composition and geometry. Here we

Clinical management of a severe skull fracture in a loggerhead sea turtle (Caretta caretta)

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract A 30.6 kg loggerhead sea turtle (Caretta caretta) presented with a 2–3‐week‐old deep head wound, left neck and right cubital lacerations, and carapace fractures. Haematology revealed a marked leukocytosis, with other values unremarkable. Initial wound‐cleaning, an antibiotic course, fluids and vitamin B supplementation were initiated. Computed

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, Volume 309, Issue 10, Page 2541-2559, October 2026.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, Volume 309, Issue 10, Page 2560-2573, October 2026.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Metformin Attenuates Behavioral Deficits and Oxidative Stress in a Preclinical Model of Autism

Developmental Neurobiology, Volume 86, Issue 4, October 2026.
ABSTRACT Autism spectrum disorder (ASD) is a complex neurodevelopmental condition lacking effective pharmacological treatments. Metformin has emerged as a candidate for drug repurposing in ASD due to its metabolic and neurobiological actions. This study evaluated the in vivo effects of metformin (400 mg/kg, orally) administered from postnatal day 21 to

Cell Type‐Specific Extracellular Vesicles in Mouse Brain: Proteomic Signatures Highlight Astrocytic GlialCAM Network and GPCR Enrichment

Glia, Volume 74, Issue 10, October 2026.
Cell type–specific EVs were isolated from mouse brain and profiled by proteomics. Each EV subtype exhibited proteomic signatures consistent with the specialized functions of its cell of origin. Astrocyte‐derived EVs (ADEVs) were enriched for the GlialCAM/MLC1 network and GPCRs.

Microplastics as Emerging Neurotoxins: Brain Accumulation, Neuroinflammation, and Neurodegeneration Risk

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
Microplastics and nanoplastics (MPs/NPs) are emerging environmental neurotoxicants capable of accumulating in the human brain through blood‐brain barrier transcytosis and olfactory transport pathways. Once within the central nervous system, MPs/NPs trigger interconnected mechanisms including NLRP3 inflammasome activation, oxidative stress ...
