An illusion induced by an illusion -perceptual filling-in of coloured negative afterimages
Visual filling-in relates to a perceptual phenomenon in which a stimulus pattern apparently undergoes dynamic changes assuming an attribute such as colour, texture, or brightness from the surround….

Can Vision Exist Without Somatosensation?
The interconnection between vision and somatosensation is already well-established and is further supplemented by the evolutionary link between eyes and photoreceptors, and the functional connectio…

Evolutionary game theory and the evolution of neuron populations, ring rates, and decisionmaking
Ours, is the first application of dynamical evolutionary games to decision making in neuroscience. Firing neurons are the players. The strategy is their firing rate. Neurons with equal firing rates…

Reward sharpens orientation coding independently on attention
Rewarding improves performance. Is it due to modulations of the output modules of the neural systems or are there mechanisms favoring more ‘generous’ inputs? Some recent study included V1 in the th…

Vision senses number directly
We have recently suggested that numerosity is a primary sensory attribute, showing that it is strongly susceptible to adaptation. Here we use the Method of Single Stimuli (MSS) to show that observe…

Cross-modal facilitation of visual and tactile motion
Robust and versatile perception of the world is augmented considerably when information from our five separate sensory systems is combined. Much recent evidence has demonstrated near-optimal integr…

Colored filters improve exclusion of perceptual noise in visually symptomatic dyslexics
Dyslexic individuals have deficits in detecting visual stimuli embedded in high levels of perceptual noise. Here we show that visually symptomatic dyslexics, who otherwise had elevated contrast thr…

Representing an Object by Interchanging What with Where
Exploring representations is a fundamental step towards understanding vision. The visual system carries two types of information along separate pathways: One is about what it is and the other is ab…

Perceptual deficits and inattention in schizophrenia
A number of investigators have found perceptual deficits in schizophrenic subjects. It has also been indicated that those with schizophrenia suffer from reduced attention. This raises the possibili…

Young children do not integrate visual and haptic information
Several studies have shown that adults integrate visual and haptic information (and information from other modalities) in a statistically optimal fashion, weighting each sense according to its reli…
