| Research Abstract |
The present study found another indirect route through motor/premotor cortex for articulation by Japanese nonword, besides the traditional indirect route through left inferior frontal gyrus (including Broca's area) by low familiarity word or nonword of alphabetic languages. Importantly, developmental stuttering speakers did not activate the Broca's area during articulation regardless of the word familiarity, while activate the motor/premotor area more intensively than non-stuttering subjects. This result imply that the stuttering speakers use another route through motor/premotor cortex to compensate the dysfunction in traditional indirect route through Broca's area during articulation.
