    How does the brain determine the position of moving objects? It turns out to be rather complex to answer this question when we realize that the brain has to solve the motion correspondence problem in two kinds of reference frames: Retinotopic and non-retinotopic ones. We show that visual objects...

    The pulvinar nucleus of the thalamus is massively interconnected to cortical areas which translate spatial visual information into coordinate systems defined by multiple reference frames [Grieve et al. (The primate pulvinar nuclei: vision and action. Trends in Neurosciences 2000; 23(1):...

    Three recent studies reported retinotopic (eye-centered) and object-centered attentional facilitation following exogenous cuing in dynamic displays. The present study replicates this finding and shows, under the very same experimental conditions, inhibition of return (IOR) in both retinotopic...

Human Perception & Performan;Aug2011, Vol. 37 Issue 4, p1110 

    Our representation of peripersonal space does not always accurately reflect the physical world. An example of this is pseudoneglect, a phenomenon in which neurologically normal individuals bisect to the left of the veridical midpoint, reflecting an overrepresentation of the left portion of space...

    Both a neuropsychological syndrome (unilateral spatial neglect) and a visual illusion of length (the Brentano version of the M�ller-Lyer illusion) bring about a misjudgement of the subjective centre of a horizontal line, with a unilateral shift. In experiment 1 we investigated, in patients...

  • Pre-Saccadic Shifts of Visual Attention.  // PLoS ONE;Sep2012, Vol. 7 Issue 9, Special section p1 

    The locations of visual objects to which we attend are initially mapped in a retinotopic frame of reference. Because each saccade results in a shift of images on the retina, however, the retinotopic mapping of spatial attention must be updated around the time of each eye movement. Mathôt and...

    The sensory signals that drive movement planning arrive in a variety of 'reference frames', and integrating or comparing them requires sensory transformations. We propose a model in which the statistical properties of sensory signals and their transformations determine how these signals are...

    The influence of radial (near-far) and vertical (upper-lower) dimensions on lateral visuo-spatial neglect was studied using two horizontal line-bisection tasks (one motor and one perceptual). A group of 15 patients with neglect and a group of 14 right-brain damaged patients without neglect were...
