Ingham, Roger J.; Grafton, Scott T.; Bothe, Anne K.; Ingham, Janis C. – Brain and Language, 2012
Many differences in brain activity have been reported between persons who stutter (PWS) and typically fluent controls during oral reading tasks. An earlier meta-analysis of imaging studies identified stutter-related regions, but recent studies report less agreement with those regions. A PET study on adult dextral PWS (n = 18) and matched fluent…

Liotti, Mario; Ingham, Janis C.; Takai, Osamu; Paskos, Delia Kothmann; Perez, Ricardo; Ingham, Roger J. – Brain and Language, 2010
High-density ERPs were recorded in eight adults with persistent developmental stuttering (PERS) and eight matched normally fluent (CONT) control volunteers while participants either repeatedly uttered the vowel "ah" or listened to their own previously recorded vocalizations. The fronto-central N1 auditory wave was reduced in response to spoken…
