To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor control still remain open. One of them is the mechanism(s) by which neurotransmitters, such as dopamine, modulate speech and song production. In this review, we bring togeth...
Background & Importance: Insular lobe is located at the depth of sylvian fissure and is hidden by frontal, temporal and parietal lobes in close vicinity of internal capsule and basal ganglia and adjacent to the speech centers in the dominant hemisphere. Thus, radical resection of insular gliomas can be even more difficult. Brain mapping techniques can be used to maximize the extent of...
This thesis aims at elucidating the role of auditory feedback in the learning and planning of complex articulatory gestures in time-varying phonemes. To this end, we studied native Mandarin speakers' responses to perturbations of their auditory feedback of the first and second formant trajectories during the production of the Mandarin triphthong /iau/. On the group level, subjects adaptively ad...
PURPOSE Advances in neurobiology are providing new opportunities to investigate the neurological systems underlying motor speech control. This study explores the perceptual characteristics of the speech of three genotypes of spino-cerebellar ataxia (SCA) as manifest in four different speech tasks. METHODS Speech samples from 26 speakers with SCA were perceptually rated by experienced listener...
The purpose of the present paper is to present a critical review and reanalysis of response generalization effects in studies of treatment efficacy in apraxia of speech (AOS). Response generalization takes two forms: generalization of treatment effects to untrained exemplars of trained behaviors and generalization to untrained (i.e., novel) behaviors. In the past, response generalization has no...
