Synchrony within Aβ mechanoreceptor subtypes governs signal propagation to primary somatosensory cortex

The Journal of Physiology, EarlyView.
Abstract figure legend We used an optogenetic gain‐of‐function manipulation to investigate how sensory signals from two subtypes of Aβ low threshold mechanoreceptors (LTMRs) contribute to the cortical representation of touch. CatCh, a sensitive and fast channelrhodopsin variant, enables pulsed‐light generation of high‐frequency action potential trains ...

Early Postoperative Adverse Events (≤ 30 Days) in Spinal Oncology: Defining the Incidence, Severity, and Predictors in a Mixed Prospective Cohort Including Intradural and Metastatic Spinal Tumors

International Journal of Cancer, Volume 159, Issue 12, Page 2962-2972, 15 December 2026.
ABSTRACT Complication reporting in spinal tumor surgery remains inconsistently defined. We aimed to quantify the incidence, severity, and spectrum of early (≤ 30 days) postoperative adverse events (AEs) in spinal tumor surgery and to identify predictors of overall and serious complications using standardized severity grading.

Astrocytic EAAT‐2 Upregulation Supports Neuro‐Axonal Homeostasis in Chronic Inflammatory CNS Lesions

Glia, Volume 74, Issue 12, December 2026.
Inflammatory CNS lesions increase extracellular glutamate. Astrocytic EAAT regulation controls glutamate clearance, stabilizes axonal Ca2+ homeostasis, and determines neurite survival during chronic neuroinflammation. ABSTRACT Neuronal loss in multiple sclerosis (MS) is a key factor in the progression of disability.

Changes in Midrange and End Range Adjacent Segment Motion 3 Years After One‐ Or Two‐Level Cervical Arthrodesis

JOR SPINE, Volume 9, Issue 4, December 2026.
ABSTRACT Background Biomechanical cadaver studies consistently find that cervical arthrodesis leads to increased motion adjacent to the arthrodesis. However, in vivo evidence indicates adjacent segment end range motion does not reliably increase at 1 year after one‐level or two‐level cervical arthrodesis.

1D Pre‐Acquisition Navigator Correcting Respiratory‐Induced Field Fluctuations in Multi‐Echo Gradient‐Echo Imaging of the Thoracic Spinal Cord

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2660-2674, December 2026.
ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

The Anatomical Record, Volume 309, Issue 11, Page 3257-3275, November 2026.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, Volume 309, Issue 11, Page 3345-3374, November 2026.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, Volume 309, Issue 11, Page 3137-3168, November 2026.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...
