However, this also means that brain rhythms can only filter input efficiently if the timing of important information is known, in particular when only present briefly.
This hypothesis is fundamental for our work, revealing how, and in which situations, brain rhythms help us cope with the continuous stream of information we receive.
This line of research is currently supported by the ANR.
We investigate rhythmic processes in the brain, with a focus on the auditory system.
Brain rhythms act as a filter that operates in time: Incoming information is amplified or attenuated, depending on the "state" (high or low excitability) of the rhythm it coincides with.
We also develop brain stimulation methods to manipulate brain rhythms. Rhythmic stimulation methods, such as transcranial alternating current stimulation (tACS), play an important part, as brain rhythms align to the externally imposed rhythm. We apply these methods to improve how brain rhythms align to rhythmic sounds, with the ultimate goal to support conditions associated with a malfunctioning of oscillatory activity.
This line of research is currently supported by the Fondation pour l'Audition.
Other ongoing research is dedicated to:
Developing methods to test for phasic effects in perception and neural responses
Testing for "true" (endogenous) oscillations in rhythmic brain responses
Revealing a tonotopical organisation of auditory brain rhythms
