Sleep architecture and social modulation of vigilance-state dynamics in the freely moving ferret

Sleep is not a uniform state: it is organized into structured cycles of substages (wakefulness, NREM, and REM sleep) whose dynamics are shaped by both internal brain processes and external experience. How social context influences these transitions remains largely unexplored, particularly in carnivores whose sleep architecture more closely resembles that of humans than rodents. The ferret, a highly social species with a well-characterized auditory cortex and an extended postnatal development, offers a compelling model in which to address these questions.

Emergence of cortical speech representations during postnatal development in the ferret

The ability to perceive and categorize speech sounds develops early in life, well before language acquisition. The neural mechanisms underlying this early plasticity, and in particular the role of auditory experience in shaping the maturation of auditory cortical areas, remain poorly understood. Our group addresses these questions using the ferret as an animal model, whose protracted postnatal brain development makes it especially well suited for experimental investigation.

Perception auditive du bruit de l'eau qui coule, chez l'être humain, dans un habitat naturel

Enregistrement d'une rivière Corse

L’originalité de cette étude tient à la méthodologie mise en œuvre pour analyser la rivière de Haute-Corse, la Bravone. Pourquoi la Corse ? Parce que ce territoire insulaire présente un trafic aérien beaucoup plus faible que la France métropolitaine, et donc, un moindre niveau de pollution acoustique d’origine humaine.

Améliorer la détection et la compréhension des troubles du développement cérébral de manière précoce avec la neuroimagerie fonctionnelle par ultrasons

Le projet fUSI vise à améliorer la manière dont on détecte et comprend les troubles du développement cérébral, tels que l'autisme et la schizophrénie, dès le début de la vie. Actuellement, beaucoup de ces troubles ne sont pas identifiés avant que les symptômes ne deviennent plus évidents et plus difficiles à traiter.

ANNULÉ - Exploring the Cognitive Foundations of Cinematic Continuity

Filmmakers tell stories by selecting and emphasizing key details of an audiovisual scene through editing, cinematography and sound design. Such edited sequences instantaneously transport the viewer through space and time in ways that are physically impossible and, due to their divergence from reality should pose problems for viewer comprehension. However, filmmakers believe they have at their disposal a suite of editing techniques, known as the Continuity Editing Rules that make the viewing of film effortless.

Human Auditory Ecology, a new interdisciplinary field

Logo MNHNThe aim of these interdisciplinary colloquia, organized as part of a partnership between the Muséum national d'Histoire naturelle and the Ecole normale supérieure (Université PSL), was to promote the scientific study of the human auditory system's ability to perceive ecological processes at work in natural habitats, by confronting hearing sciences (psychoacoustics, aud

Non-invasive brain stimulation for modulating neurochemical and neuro-oscillatory activity

Recent advances in neuromodulation combined with neuroimaging enable unprecedented insights into the mechanisms supporting human motor control and recovery after stroke. In this talk I will show how tDCS–MRI reveals targeted cortical inhibition can restore large-scale network connectivity after stroke, and how concurrent tACS–MRI links neurochemical states and oscillatory dynamics to functional connectivity during motor learning.
