Slow potentials of the brain related to speech processing in normal speakers and stutterers.

摘要: Abstract A CNV paradigm was employed to study slow potential shifts of the brain in stutterers and normal speakers during speech nonspeech verbal tasks a nonverbal manual task. Slow were recorded from Cz. iF 3 ′ 4 . It found that vertex CNVs similar tasks. Differences between groups at lateral electrode derivations both Preceding speech, four five showed larger shift left hemisphere than right, while only 22% greater right asymmetry. In condition which subjects did not speak (the “expectancy” condition) relationships found. is concluded inferior frontal areas nonstutterers performed differently even when approaching moment stuttering, i.e. , appeared have equal performance, also they making identical decisions about having difficulty speaking word although no overt motor required. The interhemispheric differences two are attributed increased “anxiety” since unaffected.
