Cover Picture Story: Experiments with Modular State Spaces

The main analysis techniques for critical systems use state space exploration. However, one is often quickly limited by the so-called state space explosion problem, even if the systems models are relatively small. Several methods have been proposed to tackle this problem in order to get a manageable state space. One of these takes advantage of the modular structure of the model in order to buil...

Rapid picture processing: affective primes and targets.

In rapid serial visual presentation of pictures, an early ERP component shows enlarged negativity over occipital regions for emotional, compared to neutral, pictures. The present study examined the processing of emotional target pictures as a function of the hedonic valence of a preceding prime picture. Dense sensor ERPs were measured while subjects viewed a continuous stream of pleasant, neutr...

Accident de travail pas très commun

Il s'agit d'un patient de 40 ans, admis au service des urgences pour un traumatisme par pistolet pneumatique à clou du membre inferieur droit. Le traitement initial à base d'amoxicilline protégée, parage et ablation du corps étranger étaient efficaces. L'aggravation clinique à une semaine d'intervalle vers un empâtement du genou et douleur à la marche. Une ponction articulaire du genou a retrou...

Sleep deprivation reduces the rate of rapid picture processing

Object recognition becomes impaired at faster presentation rates and here we show the neuroanatomical foci of where this might be exacerbated by sleep deprivation (SD). Twenty healthy human participants were asked to detect a target house in serially presented house pictures that appeared at 1-15images/s. Temporal response profiles relating fMRI signal magnitude to presentation frequency were d...
