Scientists pinpoint likely origin of stuttering in the brain

Scientists have pinpointed the brain network that's involved in stuttering, brain scans reveal. 

The work suggests that stuttering may be triggered by disruption to a specific network of brain cells, or neurons that connects three major regions of the brain. These regions — the amygdala, the putamen and the claustrum — are respectively involved in regulating emotions, controlling movements and relaying information between different areas of the brain.
