Prosodic stress: Acoustic, aphasic, aprosodic and neuroanatomic interactions

► Deficits in production of prosodic stress occur from lesions in either hemisphere. ► Left basal ganglia lesions and non-fluency predict prosodic stress deficits. ► Location of right hemisphere lesions is not predictive of prosodic stress deficits. ► Aprosodic deficits are not predictive of prosodic stress deficits. ► Aprosodic deficits, however, condition the acoustic signaling of prosodic stress
