A differential role for the posterior cerebellum in the adaptive control of convergence eye movements

open access: yesBrain Stimulation, 2020
Introduction: The vergence oculomotor system possesses two robust adaptive mechanisms; a fast “dynamic” and a slow “tonic” system that are both vital for single, clear and comfortable binocular vision.

Efficient sensory cortical coding optimizes pursuit eye movements

open access: yesNature Communications, 2016
Efficient coding suggests that adapting gain to match the varying stimulus statistics should help in optimizing behaviour. Here the authors show that adaptation in motion sensitive neurons maximizes information and improves movement accuracy in pursuit ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Bioinspired Design of a Wet‐Adhesive Cornea Glue Based on Recombinant Human Protein Networks

open access: yesAdvanced Functional Materials, EarlyView.
Natures protein‐based high performance materials e.g. elastin, silk and muscle proteins have been mimicked by a new protein‐hybrid material based on redesigned human partial sequences only, showing high wet‐adhesiveness and elasticity for biomedical applications.

Impairment of retinal adaptive circuitry in the myopic eye

open access: yesVision Research, 2011
Previous studies have proposed that the inner retina is affected in myopes. This study aimed to investigate the changes in adaptive circuitry of the inner retina in myopia, using the global flash multifocal electroretinogram (global flash mfERG) with different levels of contrast (luminance modulation).

Integration of visual stimuli by the crayfish central nervous system [PDF]

open access: yes, 1967
For the crayfish, properties of visually reacting interneurone types in the optic nerve are described on the basis of single-unit analysis. Sustaining fibres show: (a) ‘surround’ inhibition over the whole retina, including the excitatory field; (b) ‘on’

A Differential Approach for Gaze Estimation

open access: yes, 2019
Non-invasive gaze estimation methods usually regress gaze directions directly from a single face or eye image. However, due to important variabilities in eye shapes and inner eye structures amongst individuals, universal models obtain limited accuracies ...

A Bioengineered Model of the Human Cornea for Preclinical Assessment of Human Ocular Exposure to Environmental Toxicants

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper presents a microphysiological system containing an array of individually addressable living corneal tissues constructed using primary human cells. The bioengineered eye model can simulate acute exposure of the human cornea to different types of environmental toxicants and provides a novel platform for visualization and quantitative ...
