Hemodynamics of speech production: An fNIRS investigation of children who stutter

Abstract Stuttering affects nearly 1% of the population worldwide and often has life-altering negative consequences, including poorer mental health and emotional well-being, and reduced educational and employment achievements. Over two decades of neuroimaging research reveals clear anatomical and ph...
