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 ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, Volume 309, Issue 10, Page 2656-2697, October 2026.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

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.

Most Early‐Born Subplate Neurons Persist as Layer 6b Neurons in the Adult Mouse Neocortex

Journal of Comparative Neurology, Volume 534, Issue 10, October 2026.
Comprehensive EdU birthdating and 3D volumetric analyses revealed that most early‐born subplate neurons (SpNs) persist into adulthood as layer 6b (L6b) neurons in the mouse neocortex. Green circles indicate SpNs/L6b neurons, and magenta labeling indicates EdU‐labeled early‐born neurons.

Development of Thalamo‐Telencephalic Circuits in a Reptile

Journal of Comparative Neurology, Volume 534, Issue 10, October 2026.
The development of forebrain connections was investigated in the Alligator. Four circuits were identified: ipsilateral basal nuclei to the dorsal thalamus, ipsilateral lateral forebrain bundle, and ipsilateral and contralateral medial forebrain bundle.

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.
