[Covid – 19] En raison de la situation actuelle, par mesure de prévention et de protection de santé publique, nous avons décidé de reporter à l'année prochaine les cinq conférences prévues du 16 au 20 mars à l'ENS.
La 22e édition de La Semaine du Cerveau a lieu du 16 au 22 mars 2020. Cet événement est organisé en France par la Société des Neurosciences.

Josh McDermott (MIT): "Computational auditory scene analysis as causal inference"
Adaptive decision-making requires precise monitoring of decision quality in light of both sensory uncertainty and the variability inherent in cognitive functions. Such monitoring, or metacognitive reasoning, can be assessed by relating subjective confidence in a perceptual decision to objective accuracy. Selective attention is a known modulator of sensory processing, and reliable metacognitive access to attention may be the key to cope with the variability of the environment.
Josh McDermott: Computational auditory scene analysis as causal inference
Several evidences indicate that visual experience during development is fundamental to acquire long-term spatial capabilities. Specifically, it has been hypothesized that vision is crucial to acquire the ability to code space according to allocentric frames of reference, namely based on external landmarks compared to our own body. For instance, the first attempts of sighted children to code space by relying on allocentric landmarks have been reported at 8.5 months of age, with constant improvements throughout primary school years.
In this talk I will describe studies that explored the spatial distribution of attention with a measurement that is independent of performance - the pupillary light response (PLR), thereby avoiding various obstacles and biases involved in more traditional measurements of spatial covert attention. Previous studies demonstrated that when covert attention is deployed to a bright area the pupil contracts relative to when attention is deployed to a dark area, even though display luminance levels are identical and central fixation is maintained.
On sait que la surdité dans la petite enfance entraîne des changements durables dans la façon dont les sons sont traités par le cerveau. Mais de nouvelles recherches publiées récemment dans eLife montrent que des niveaux légers à moyens de perte auditive chez les jeunes enfants peuvent entraîner des changements similaires. Ces résultats pourraient avoir des répercussions sur la façon dont le dépistage de la surdité est réalisé chez les bébés et sur la façon dont la perte auditive légère à modérée chez les enfants est prise en charge par les professionnels de santé.
The world teems with complex sounds that animals have to interpret in order to survive. To do so, their brain must represent the richness of the sounds' acoustic structure, from simple to high-order features. Understanding how it does it, however, remains filled with challenges. In this thesis, these questions were explored through a new technical prism, namely functional UltraSound imaging (fUSi). First, fUSi was used to investigate with a high fidelity the topographical organization of the auditory system, as well as its connectivity with other brain areas.
