The brain is a remarkably complex structure, which evolves throughout life, following experiences, positive and negative, and learning, a phenomenon called \u201c experience-dependent brain plasticity<\/a>\u201d. The types of experiences that include amateur-level musical activities, such as singing, playing an instrument, but also learning a second language, acting and all other activities that have a strong vocal or auditory component. These activities alter brain structure and function and can have positive effects on communication and cognition. The key idea here is that these changes can alter aging trajectories, leading to more positive aging. These activities therefore have significant potential for prevention and rehabilitation. Yet, we still know too little about their impact on the brain and on communication to be able to use them effectively as a prevention or a treatment strategy. It is therefore imperative to study how these activities can affect the adult and aged brain.<\/p>

In addition to focusing on activity-induced plasticity, we are also interested in plasticity induced by non-invasive brain stimulation. We use a method called MRI-guided transcranial magnetic stimulation <\/a>(TMS) to temporarily modify brain activity and study its impact on the ability to understand or produce language in healthy people and in people with cognitive disorders. We measure the effects of TMS using behavioral tests as well as TMS-compatible electroencephalography <\/a>(EEG), which allows us to visualize and measure the impact of stimulation on brain activity during and immediately after TMS.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
