Promising Neuroscience Methods in Exploring the Spatiotemporal Mechanisms underlying Speech Motor Control

Abstract

Speech motor control is a complex neuromotor behavior that requires the combined efforts of feedforward control and feedback control subsystems. With the advent of neuroscience, multiple lines of research have explored the spatiotemporal mechanisms underlying this process. The purpose of this review was to point out several promising neuroscience methods and their unique values in enriching the speech motor control literature. We discussed the clinical value of noninvasive brain stimulation methods, and the theoretical value of invasive brain recording methods, as well as the predictive value of brain connectivity techniques. Based on prior findings, we propose a roadmap for future research, identifying structure-function coupling that supports speech motor control.
