Neural mechanisms for short-term shifts of interocular balance

Abstract: Recent studies in adult humans have shown that short-term deprivation of one eye (1-3hrs) dramatically shifts the balance in favor of this eye for over an hour afterwards. This surprising result runs counter to the classical understanding of both the limits of adult cortical plasticity as well as the Hebbian nature of monocular deprivation. The STMD paradigm, then, has uncovered a poorly understood yet important feature of early binocular integration.

Cognition does not affect perception

What determines what we see? A tidal wave of recent research alleges that visual experience is 'penetrated' by higher-level cognitive states such as beliefs, desires, emotions, intentions, and linguistic abilities. There is a growing consensus that such effects are ubiquitous, and even that the distinction between seeing and thinking may itself be unsustainable. I argue otherwise: There is in fact no

Feedback processing in monkey visual cortex

Our perception is an inherently active process. We dynamically select information that is behaviorally relevant for us at given moments in time, enabling us to interact effectively with the world around us. This ability is thought to depend on feedback from higher cortical areas to early sensory areas, but this process remains poorly understood. One issue in investigating feedback processing is that it is generally activated at the same time as feedforward processing, making it hard to distinguish one from the other.

  • Philipe Schlenker, chercheur CNRS à l'Institut Jean-Nicod, pour le projet ORISEM. Ce projet a pour objectif de poser les bases d'une théorie générale (la « super sémantique ») qui a pour but de développer une analyse comparée de la signification dans le langage (langues parlées et langues signées), dans les gestes, dans la musique, et dans la communication primate, et également d'en explorer les origines cognitives et évolutives.
