Electrophysiological evidence for an early processing of human voices

<p>Abstract</p> <p>Background</p> <p>Previous electrophysiological studies have identified a "voice specific response" (VSR) peaking around 320 ms after stimulus onset, a latency markedly longer than the 70 ms needed to discriminate living from non-living sound sources and the 150 ms to 200 ms needed for the processing of voice paralinguistic qualities. In the present study, we investigated whether an early electrophysiological difference between voice and non-voice stimuli could be observed.</p> <p>Results</p> <p>ERPs were recorded from 32 healthy volunteers who listened to 200 ms long stimuli from three sound categories - voices, bird songs and environmental sounds - whilst performing a pure-tone detection task. ERP analyses revealed voice/non-voice amplitude differences emerging as early as 164 ms post stimulus onset and peaking around 200 ms on fronto-temporal (positivity) and occipital (negativity) electrodes.</p> <p>Conclusion</p> <p>Our electrophysiological results suggest a rapid brain discrimination of sounds of voice, termed the "fronto-temporal positivity to voices" (FTPV), at latencies comparable to the well-known face-preferential N170.</p

Post-socialist Europe and its “Constitutive Outside”: ethnographic resemblances for a comparative research agenda

The “post-Socialist Europe” label has been criticized for not being able to fully capture post-1989–91 social and cultural processes in Central and Eastern Europe and Russia. While some ask what was Socialist Europe?, I interrogate non-post-Socialist Europe today. This chapter examines, from a historical-ethnographic comparative perspective, present-day fragmented resemblances and disjunctures between Eastern and Western Europe, contextualizing them within their (Socialist) antecedents. By focusing on the local governance of marginalized Romani families in Cluj-Napoca (Romania) and Florence (Italy), I show that in both temporal regimes (pre- and post-1989) the two cities display ethnographic resemblances. However, rather than creating disparities and hierarchies, I point to the importance of ethnographic comparisons between the margins of the “West” and the “East” in order to de-dichotomize and refine our knowledge

Ecologie de la santé: Pour une nouvelle lecture de nos maux

Prod 2017-108 EA BIOmE CT ? INRANational audienceQuand l'écologie pose son diagnostic. L'actualité nous le rappelle sans cesse : les maladies comme le paludisme, le Sida, ébola ou zika sont difficiles à combattre, et les maladies chroniques de type cancer, diabète ou maladies cardio-vasculaires toujours plus meurtrières. Pour la première fois de son histoire, l'humanité voit même son espérance de vie diminuer. Pour comprendre les raisons de cette crise sanitaire, l'écologie scientifique pose un autre regard sur la santé qui prend en considération les transformations de l'environnement et l'évolution de nos modes de vie. Cette nouvelle approche évolutive et écologique des problèmes de santé tente d'élucider les mécanismes en jeu dans la transmission et l'émergence de nouveaux pathogènes, mais aussi dans la résistance toujours croissante aux antibiotiques. Elle permet de mesurer l'effet des facteurs environnementaux sur la santé : concentration urbaine et industrielle et nouveaux comportements induits en matière d'alimentation et d'activités physiques. Cet ouvrage rédigé par des spécialistes issus des laboratoires du CNRS ou associés fait le point sur les recherches en écologie de la santé. Il permet à chacun de comprendre pourquoi il est essentiel de remonter aux sources environnementales et comportementales de nos maux, et de ne pas se limiter aux symptômes
