A Whole‐Head Finite Element Model for Electrical Neuromodulation via Visual Brain‐Machine Interfaces

Advanced Science, EarlyView.
A multimodal, personalized head model is presented that integrates the entire visual pathway with surrounding tissues to simulate electrical stimulation of the optic nerve. In vivo validation in humans and goats, plus systematic component‐elimination analysis, demonstrates the high accuracy of the comprehensive model.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Cerebellar Abnormalities in the Neuroimaging Spectrum of CLTC‐Related Disorder

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in CLTC, which encodes the clathrin heavy chain involved in vesicle‐mediated trafficking in neurons, cause a rare neurodevelopmental disorder associated with variable severity of global developmental delay and intellectual disability and structural brain abnormalities. Although corpus callosum and white matter anomalies are

Autonomic Nerve Fiber Compositions of Zygomaticotemporal and Lacrimal Nerves: A Cadaveric Immunohistochemical Analysis

International Forum of Allergy &Rhinology, EarlyView.
Key Points Zygomaticotemporal (ZTN) and lacrimal nerves (LN) both carried sympathetics and parasympathetics ZTNs had more parasympathetics than LNs, but markers varied significantly within and between nerves LN parasympathetics to the lacrimal gland may mitigate dry eye after vidian ...

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

The Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

The nonlinearity of passive extraocular muscles [PDF]

Annals of the New York Academy of Sciences, 2011
Passive extraocular muscles (EOMs), like most biological tissues, are hyperelastic, that is, their stiffness increases as they are stretched. It has always been assumed, and in a few occasions argued, that this is their only nonlinearity and that it can be ignored in central gaze.
