Transient periods of synchronized oscillating neuronal discharges in the brain have been proposed to support the discrete perceptual moments underlying conscious visual experience. However, the information content of these perceptual moments remains a critical challenge to the understanding of consciousness. We uncovered this information content in four observers who consciously perceived each ...

une fois installé dans l’espace, l’homme commence à le reconstruire. se sentant seul et se réfugiant dans un «coin», il partage sa solitude avec l’espace. de plus, en partageant ses souvenirs et ses rêves avec des objets, il estime que la  géométrie est transcendée. à cet égard, la topo-analyse, l'idée représentée par gaston bachelard, vise à étudier psychologiquement les sites intimes de la vi...

We address this problem in a case study that involves the perceptual reversal of an ambiguous image (here, Dali's painting the Slave Market with the Disappearing Bust of Voltaire 1940). In experiment 1, we use 'bubbles' (Gosselin and Schyns, 2001 Vision Research 41 2261-2271) to disambiguate the image ...
