Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Data‐driven thresholds for standardized classification of severe Alzheimer's disease neuropathology using digital neuropathology

Brain Pathology, EarlyView.
We generated digital pathologic algorithms (AI‐based modules that can be freely shared) to: optimize the sampling (ROI) for diagnosis of ADNC‐related tau pathology; compare/transition between Aperio and HALO platforms; and rationalize severe Braak NFT staging, so that all Braak‐VI cases had dementia, and all Braak‐V cases had MCI or dementia.

Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

Brain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...

Clinicopathological and molecular heterogeneity of amyloid‐β in unnatural deaths under 70 years: A forensic autopsy–based study

Brain Pathology, EarlyView.
This study investigates amyloid‐beta (Aβ) pathology in a forensic autopsy cohort of relatively young individuals (40–69 years). Using detailed immunohistochemical analyses of multiple Aβ species, we demonstrate marked regional and molecular heterogeneity, particularly within the striatum.

Serotonin engages divergent 5‐HT receptor pathways for cell type‐resolved modulation of prefrontal layer 5 microcircuits

British Journal of Pharmacology, EarlyView.
Serotonin differentially modulates layer 5 mPFC microcircuits through cell type‐specific pre‐ and postsynaptic receptor pathways. Presynaptic 5‐HT1BRs suppress glutamate and GABA release, whereas presynaptic and postsynaptic 5‐HT3ARs enhance fast‐spiking interneuron activity, whilst distinct pyramidal neuron subtypes exhibit divergent 5‐HT1AR‐ and 5 ...

Neurodevelopmental and neurological features in children with hypochondroplasia

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To assess neurodevelopmental and neurological features, including neuroimaging abnormalities, in children with molecularly confirmed hypochondroplasia. Method A retrospective cohort study of children with molecularly confirmed hypochondroplasia seen at Evelina London Children's Hospital skeletal dysplasia service was performed.

Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.
