Crowding, Patterns and the Fundamentals of Vision

Abstract:

In most models of vision, low level visual tasks are explained by low 
level neural mechanisms. For example, in crowding, perception of a 
target is impeded by nearby elements because, as proposed, responses of 
neurons coding for nearby elements are pooled. Indeed, performance 
deteriorated when a vernier stimulus was flanked by two lines, one on 
each side. However, performance improved strongly when the lines were 
extended to squares. Classic models cannot explain this uncrowding

La liberté vue par les neurosciences


Que signifie être libre? Normalement, on se sent libre de faire nos propres choix. Néanmoins, notre environnement peut nous influencer, même sans que l'on s'en aperçoive ! Dans ce cas, sommes-nous responsables de nos actions? Venez découvrir ce que les neurosciences cognitives nous apprennent sur la liberté humaine.

Neural processing of speech in children with sensorineural hearing loss

Although the primary damage associated with sensorineural hearing loss lies in the cochlea,
its consequences extend throughout the entire auditory pathway. Despite having significant
residual hearing, children with mild (21-40 dB HL) to moderate (41-70 dB HL) sensorineural
hearing loss (MMHL) experience deficits with general auditory processing, which puts them at risk
of encountering language difficulties. Here, I will present two studies aimed at better understanding

Gaze and Locomotion in Natural Terrains

Eye movements in the natural world reflect the information needs of the momentary behavioral goals, the rewards and costs associated with those goals, and uncertainty about the state of the world. We examine how these factors trade off in the context of walking outdoors in terrains of varying difficulty, a situation where little is known about how visual and locomotor systems work together to achieve efficient and stable behavior. We developed a novel system to simultaneously record gaze and full-body kinematics during locomotion.
