White matter correlates of sensorimotor synchronization in persistent developmental stuttering.

ABSTRACT:

Introduction

Individuals with persistent developmental stuttering display deficits in aligning motor actions to external cues (i.e., sensorimotor synchronization). Diffusion imaging studies point to stuttering-associated differences in dorsal, not ventral, white matter pathways, and in the cerebellar peduncles. Here, we studied microstructural white matter differences between adults who stutter (AWS) and fluent speakers using two complementary approaches to: (a) assess previously reported group differences in white matter diffusivity, and (b) evaluate the relationship between white matter diffusivity and sensorimotor synchronization in each group.

Methods

Participants completed a sensorimotor synchronization task and a diffusion MRI scan. We identified the cerebellar peduncl
