Fooling the eyes: the influence of a sound-induced visual motion illusion on eye movements [PDF]

open access: yes, 2013
The question of whether perceptual illusions influence eye movements is critical for the long-standing debate regarding the separation between action and perception.

Intrasession repeatability of ocular anatomical measurements obtained with a multidiagnostic device in healthy eyes

open access: yesBMC Ophthalmology, 2017
Background To evaluate the intrasession repeatability of anterior chamber depth (ACD), central (CCT) and peripheral corneal thickness (PCT), white-to-white diameter (WTW), and irido-corneal angle (IA) measurements obtained with a multidiagnostic device ...

Perceiving pictures [PDF]

open access: yes, 2011
I aim to give a new account of picture perception: of the way our visual system functions when we see something in a picture. My argument relies on the functional distinction between the ventral and dorsal visual subsystems.

Perisaccadic visual perception

open access: yesJournal of Vision, 2017
Primates use frequent, rapid eye movements to sample their visual environment. This is a fruitful strategy to make the best use of the highly sensitive foveal part of the retina, but it requires neural mechanisms to bind the rapidly changing visual input into a single, stable percept. Studies investigating these neural mechanisms have typically assumed

Mesolimbic confidence signals guide perceptual learning in the absence of external feedback

open access: yeseLife, 2016
It is well established that learning can occur without external feedback, yet normative reinforcement learning theories have difficulties explaining such instances of learning.

Validation of Digital Applications for Evaluation of Visual Parameters: A Narrative Review

open access: yesVision, 2021
The current review aimed to collect and critically analyze the scientific peer-reviewed literature that is available about the use of digital applications for evaluation of visual parameters in electronic devices (tablets and smartphones), confirming if ...

Clinical Validation of a New Optical Biometer for Myopia Control in a Healthy Pediatric Population

open access: yesChildren, 2022
To assess the clinical validation of the Myah device in a pediatric population by evaluating the repeatability of biometric evaluations and analyzing its agreement with the Myopia Master system. A total of 51 children (51 eyes) were enrolled.

Visual adaptation to goal-directed hand actions [PDF]

open access: yes, 2004
Prolonged exposure to visual stimuli, or adaptation, often results in an adaptation “aftereffect” which can profoundly distort our perception of subsequent visual stimuli.

No effect of attentional modulation by spatial cueing in a masked numerical priming paradigm using continuous flash suppression (CFS) [PDF]

open access: yesPeerJ, 2023
One notion emerging from studies on unconscious visual processing is that different “blinding techniques” seem to suppress the conscious perception of stimuli at different levels of the neurocognitive architecture.

Contextual modulation of primary visual cortex by auditory signals [PDF]

open access: yes, 2017
Early visual cortex receives non-feedforward input from lateral and top-down connections (Muckli & Petro 2013 Curr. Opin. Neurobiol. 23, 195–201. (doi:10.1016/j.conb.2013.01.020)), including long-range projections from auditory areas.
