Outline of Final Research Achievements

For the stuttering which is a speech disorder with dysfluency, brain activities and biological signals simultaneously were measured during speech or speech imagery for the investigation of the neural basis of fluent speech before a study of a fluency training using fMRI neurofeedback.
Besides, brain morphology in adults with stuttering (AWS) was compared with that in adults with no stuttering (ANS) and was investigated of the relation to psychological traits or stuttering severity. As a result, the volume in the left cuneus and fusiform in the AWS were smaller than those in the ANS. In addition, these results suggested that the psychological traits have an influence on the brain morphology in AWS.
