Our goal is to understand how the neurobiological systems that underlie communication change with age, and to identify the impacts that these changes can have on communication, both in terms of language expression and language reception. Our work has highlighted significant articulatory and perceptual difficulties in the elderly. We have demonstrated that these difficulties are associated with changes in the structure of the brain, both in terms of gray and white matter, as well as with changes in the functioning of the brain in several networks, including the dorsal speech stream, the motor system and the salience network.

To tackle this important question, we use multimodal (functional, structural, diffusion) magnetic resonance imaging (MRI), electroencephalography (EEG) and transcranial magnetic stimulation (TMS) to study the effects of aging on the brain, which we combine to behavioural, bioacoustics and cognitive approaches to understand the impact of brain aging on communication, social participation and quality of life.
