| Outline of Final Research Achievements |
This study examined the cerebral blood responses in the left frontal cortex for speech production in normal controls (PWNS) and people who stutter (PWS) by means of non-invasive near-infrared spectroscopy (NIRS). Significant interaction effects were found between the subject groups and word categories (Japanese familiar, unfamiliar, and pseudo- words) in cerebral blood response at the left Brodmann’s Areas (BA) 46. Whereas the broca’s area (BA44 and 45) had not a significant difference between the subject groups. These findings suggest that the left BA46 is associated with word familiarity of the left BA46 was different between PWS and PWNS in speech production. This study shows a new method that can be used to quantify neural responses during speech production. Future studies could use the same or revised method in children who stutter to better understand the developmental problem of stuttering.
