Abstract: Developmental stuttering is a popular speech disorder, about which there has been a hypothesis that laterality of brain speech function could be abnormal in stutterers. Recently, the evidences from neuroimaging studies of developmental stuttering support this classical hypothesis as well, and indicate that the temporal system responsible for speech monitoring, and the frontal system as well as subcortical structures related with speech motor control are dysfunctional, which impair precise timing for speech production. According to these, researchers argue the brain mechanism of stuttering with the neural networks, and suggest that “two-loop” networks including multiple brain regions involved in speech production could be disrupted

Key words: developmental stuttering, laterality, speech monitoring, speech motor control, two-loop networks
