Adult participants with a range of reading abilities will receive transcranial random noise stimulation (tRNS) while they perform an artificial orthography learning task. This task simulates letter-speech sound learning, an important first step during reading acquisition known to be impaired in individuals with developmental dyslexia. The effects of the intervention will be assessed using both behavioral measures and functional magnetic resonance imaging (fMRI).",[29,30,31,32,33],"Dyslexia, Developmental","Reading","Dyslexia","Learning","Learning Disabilities",[31,35,36,37,38,39,40,41,42],"tRNS","transcranial electrical stimulation","non-invasive brain stimulation","neuromodulation","reading","functional magnetic resonance imaging","fMRI","audiovisual-learning","RECRUITING","2026-05-19",{"date":46,"type":47},"2026-05-22","ACTUAL",{"date":49,"type":47},"2026-04-23",{"date":51,"type":23},"2027-06",{"name":53,"class":54},"Silvia Brem","OTHER",""]
