Neural changes after training with transcranial direct current stimulation to increase speech fluency in adults who stutter

Description: In a previous randomised controlled trial (https://doi.org/10.1093/brain/awy011), we found that a five-day intervention combining anodal transcranial direct current stimulation over the left inferior frontal cortex with temporary speech fluency enhancing techniques reduces stuttering. We also measured the neural changes associated with the intervention, using functional MRI during sentence reading before the training and one-week later. We report these findings in a preprint paper (https://osf.io/8st3j) and the associated group statistic maps are available here.
