| summary | Despite recent progresses in our understanding of sensorimotor integration in speech learning, a comprehensive framework to investigate its neural basis is lacking at behaviorally relevant timescales. Structural and functional imaging studies in humans have helped identify brain networks that support speech, but fail to capture the precise spatiotemporal coordination within the networks that takes place during speech learning. Rhythmic neural oscillations (brain rhythm) in the central nervous system are thought to underlie many different cognitive and motor functions. The use of neural phase synchrony illuminates how brain rhythms in different EEG (electroencephalographic) frequency bands, which subserve distinct functional networks, communicate. In this talk I examine the hypothesis that emergent phase synchrony patterns tap into neural communication within brain networks at timescales relevant for normal and disordered speech motor functions. This idea is elucidated by showing how altered neural communication tracks the formation of feedforward map in speech motor adaptation under altered auditory feedback and how compromised neuronal communication underlies disfluency in adults who stutter. |
