Au Naturel

Although adaptation is a ubiquitous property of neurons in the early visual pathway, the functional consequences in the natural visual environment are unknown. In this issue of Neuron, Mante et al. show, through a comprehensive set of in vivo experiments in the visual thalamus, that the basic functional mechanisms of adaptation that have been well studied with artificial probes capture the neur...

Expertise et système de recherche d'informations en dialogue naturel : vers une considération des connaissances utilisateur

Based on the theory of interaction, the model we introduce first represents the knowledge the user has on his search domain. In a second time, this model implements agent behaviour rules based on experimental results in cognitive ergonomy. We illustra...
