Fourteen right-handed stutterers and 14 normal speakers responded to monaurally presented stimuli with their right and left hands. Results suggested a bilateral model of neurolinguistic organization for stutterers in which both hemispheres must participate simultaneously in the decoding process. (Author/DB)

Analysis of use of positron emission tomographic measurements of resting-state regional cerebral blood flow in 29 men, 10 of whom stuttered, did not support the idea that developmental stuttering is associated with abnormalities of blood flow at rest. Findings did suggest an essentially normal functional brain terrain with a small number of minor…
