Luc Arnal and Diane Lazard are Research Officers at the Institut Pasteur in Paris, where they co-lead a research team focused on auditory cognition and communication. Their work integrates psychoacoustics, neuroimaging (fMRI, EEG, intracranial electrophysiology), and computational modeling to investigate how the human brain processes verbal, nonverbal, and musical signals. Their research addresses fundamental and clinical questions related to hearing loss and neurodegenerative conditions such as Alzheimer's disease.
Their research interests center on the neural mechanisms underlying speech and music processing, with a particular focus on predictive coding and neural oscillations. They study how the brain adapts to sensory deficiencies, including long-term cortical reorganizations in response to hearing loss. A key area of investigation is the impact of 'rough' sounds on both classical and non-classical (limbic and subcortical) auditory pathways, and how this processing is altered in neurodevelopmental and neurodegenerative disorders. They also explore audio-visual integration, particularly lip-reading abilities in hearing-impaired individuals, using behavioral and neuroimaging methods to understand the neural basis of multisensory perception and its developmental constraints.
Their recent publications reveal trends in auditory neuroscience, particularly the role of neural rhythms in perception and the brain's adaptive strategies in hearing impairment. Their work bridges fundamental cognitive neuroscience with translational applications for diagnosing and treating hearing disorders.
They mentor PhD students and are involved in major research projects such as AUDIOGENAGE, which aims to develop precise audiological tests for age-related hearing loss, and cross-functional studies on brain connectivity diseases.
Their team operates within the broader research ecosystem of the Institut Pasteur, collaborating on interdisciplinary projects that connect auditory neuroscience with public health and disease mechanisms.
