To train or not to train?
Visual restitution training may improve the vision of people with hemianopia, yet not all patients benefit equally from this long and exhaustive procedure. Would it not be great if we could predict who will benefit and who will not? In … Continued
Tiny is beautiful!
Assessing population receptive field (pRF) properties is fundamental to understanding the neural basis of human sensory and cognitive behaviour. However, current approaches require making numerous a priori assumptions which is undesirable. In a recent paper in the journal “Neuroimage” Joana … Continued
Postdoc: computational visual neuroscience and eye-movements
(This position is no longer available, but do contact Frans Cornelissen in case you are looking for a position and recognize yourself in the below description. ) We have an immediate position available (0.8-1.0 fte) for a postdoctoral scientist with … Continued
Connecting the dots
When studying the plasticity of the human visual brain, neuroscientists have always emphasized the study of the receptive field properties of neurons. In a review and opinion paper in the journal “Neural Plasticity”, Joana Carvalho and co-authors argue there are … Continued
Treating your brain’s hubs with a magnet
Visual hallucinations (VH) are conscious visual perceptions that occur in the absence of an external physical stimulus. Some patients may have VH that are so frequent or disturbing that they seek treatment for these. In this paper in the journal … Continued
Fixels fix the picture of the brain in glaucoma
In the ophthalmic disease glaucoma, the visual pathways from the eye to the brain get damaged, but why this happens is still debated. In a paper in the scientific journal “Investigative Ophthalmology and Vision Science (IOVS)”, Shereif Haykal and colleagues … Continued
Sights unseen
Visual hallucinations are perceptions without a physical stimulus to relate the percept too. People who suffer from psychosis often experience visual hallucinations, but the properties of these hallucinations are not well known yet. Marouska van Ommen and co-authors published a … Continued
Visual hints make you see better
In games, hints can help you play a game faster or better. Also perception can use hints – often referred to as cues or “previews” – such that it becomes better. But what aspect of these visual hints does our visual … Continued
Observing half a brain
What happens to the visual system of the brain if one hemisphere gets removed completely at a late (age 3) developmental stage? In a paper published in the journal “Neural Plasticity”, Hinke Halbertsma and co-authors revisited the visual field maps … Continued
Art that moves you
On August 21st, Frans Cornelissen gave a presentation at the Noorderzon Festival in Groningen about “The Art of Vision”. The presentation was part of a trio of presentations together with Iris Sommer and Barend van Heusden under the title “Art … Continued
A I or A eye, that’s no longer the question
Eye movements are an integral and critical part of our normal visual behavior, and evaluating these may offer valuable insights for clinical interventions, diagnostics, and understanding visual perception. With raising interest in studying... READ MORE
Grant awarded for the “Virtual Reality for enhanced Visual Rehabilitation” (VR4eVR) project
Visual rehabilitation for hemianopia, which may be necessary after a stroke, can take a long time. Wouldn’t it be very useful if one could do this in the comfort of one’s own home?... READ MORE
Visual Hallucinations and the Curious Absence of Activity in the Primary Visual Cortex
Visual hallucinations are perceptions without a physical stimulus to relate this percept too. It affects millions of people, yet surprisingly little is known about what’s happening in the brain during visual hallucinations. Marouska... READ MORE
The details are in the contrast
There is a need for simpler methods of perimetry – the measurement of retinal sensitivity at different visual field locations. In a recent paper in the journal Vision Research, Anne Vrijling, Minke de... READ MORE
