Stuttering: Stop signals in the brain disturb speech flow

(Max Planck Institute for Human Cognitive and Brain Sciences) 'G-g-g-g-g-ood morning' is a daily obstacle for people who stutter. However, so far, not much is known about the causes of persistent developmental stuttering, which is the most frequent speech disorder. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, have recently discovered that a hyperactive network in the right frontal part of the brain plays a crucial role in this deficit. It inhibits speech movement planning and execution, thereby interrupting the flow of speech.
