Brain waveforms reconstructed at source level, like in beamforming, suffer polarity indeterminacy, which precludes direct group averaging of associated waveforms. We describe a polarity alignment method as an alternative of averaging rectified (i.e. absolute value) waveforms. Using MEG from an auditory localisation task, we compare the ability of t...

Since the end of 2018, practicing members of the Association des Médecins Francophones du Canada (MdFC) can now prescribe to their patients visits to the museum through an agreement with the Montreal Museum of Fine Arts (MMFA). This article is a cross-examination between psychology and art history, a discipline considered as an extraordinary school...

Distributed imaging and spatial filtering are the most commonly-used methods for reconstructing source activity. They provide for each putative source either the patterns of activity of three orthogonal co-localized dipoles or a single resultant activity constraining the orientation. For inter-subject comparisons or visualization convenience this l...

The unisensory nature of the primary visual cortex is questioned by an increasing number of studies. Here we explore the time course of the response of several “visual areas” following spatial auditory stimulations and we investigate the presence of lateralization effects.

Drawing inferences about cognition from brain imaging raises epistemological and ethical challenges in Mind, Brain, Education field. This requires substantial mathematical modeling, certainly more than commonly assumed. We propose to shed light on how recent methods in neuroimaging aim at stretching the limits of concurrent temporal and spatial res...

In neuroimaging, the mapping of brain activity from nonivasive magnetoencephalographic signals (MEG) can be formalized in a Bayesian statistical framework in which a model is compared to experimental data. We questioned to which extent the brain anatomy could be identified from the neural signature of its activity captured with MEG. We used MEG sig...

We used magnetoencephalography to investigate the nature of the underlying plastic mechanisms related to the onset of blindness. We show here the temporal course, strength, and extent of occipital activation at scalp level of congenital (n=11), late blind (n=7) and sighted(n=12) individuals; and we report the event-related spectral perturbations al...

Stimulus rivalry refers to the sustained periods of perceptual dominance that occur when different visual stimuli are swapped at a regular rate between eyes. This phenomenon is thought to involve mainly eye-independent mechanisms. Although several studies have reported that attention can increase image predominance in conventional binocular rivalry...

The Traité des Pêches, published in the eighteenth century by Duhamel du Monceau in the Description des arts et métiers remains a work of reference. Indeed, it pursues both a documentary and didactic ambition. This paper analyzes the philosophical and political framework of the treatise. It shows how resource conservation and economic efficiency ju...

L'analyse statistique implicative (ASI) est une méthode d'analyse de données non symétrique, conçue par Régis Gras il y a plus de trente ans. A travers thèses, articles de revues, livres et colloques, elle a été développée et l’est encore par lui, par des doctorants ou avec la collaboration d'équipes de recherche universitaires en France et à l'étr...
