Research studies in stuttering have shown that activity patterns in certain brain areas
differ in people who stutter compared to people who do not stutter when speaking. The purpose
of this study is to investigate how mild, non-invasive brain stimulation applied
consecutively for five days affects speech relevant brain areas, which may in turn affect
speech fluency and speaking-related brain activity in people who stutter.
