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.

Abstract: Auditory-vocal communication requires the coordinated
development of sensory and motor circuits around sounds that convey
social information. When communication sounds are learned, the brain
must use experience to build auditory and vocal motor circuits that
are functionally coupled to perceive and produce the same acoustic
signals. Unlike other animals, humans and songbirds learn the
vocalizations they use to communicate. Behavioral studies of speech
and song perception suggest that early vocal learning shapes auditory

The pupil is primarily regulated by prevailing light levels, but is also modulated by perceptual and attentional factors. We have investigated multiple cases where pupil constriction reflects attention to light, light detection during eye-movements (reflecting saccadic suppression) and illusory perception of light stimuli. This clearly indicates that cortical visual processing feeds into the pupillary control system, producing slight but consistent constrictions and dilations.

Le but de nos travaux est de progresser dans la compréhension des
processus de récupération des fonctions auditives et langagières après
implantation cochléaire ou prothèse auditive.

Résumé : We used 2-photon calcium imaging and improved analysis methods to record the responses of >10,000 neurons in the visual cortex of awake mice, to thousands of natural images. The recorded population code was high-dimensional, with the variance of its dimensions following a power law. This power law did not reflect the statistics of natural images, as it persisted even when presenting spatially whitened stimuli. A mathematical analysis showed that neural rate vectors lying in a set of fractal dimension d must have variances bounded by a power law of exponent 1+2/d.

The two-headed, dual process view of human thinking has been very influential in the cognitive sciences. The core idea that thinking can be conceived as an interplay between a fast-intuitive and slower-deliberate process has inspired a wide range of psychologists, philosophers, and economists. However, despite the popularity of the dual process framework it faces multiple challenges. One key issue is that the precise interaction between intuitive and deliberate thought processes (or System 1 and 2, as they are often referred to) is not well understood.
