Stuttering Research and Treatment

Differences in dynamic motor selection in stuttering

This study investigates temporal organisation of hand action selection in people who stutter (PWS) compared to typically fluent speakers (TFS) using MEG, finding weaker mu/beta modulation during high uncertainty periods.

Cortical tracking of speech is reduced in adults who stutter when listening for speaking

This study examines cortical tracking of speech in adults who stutter compared to fluent adults, finding reduced theta-band tracking and altered connectivity during speech-related listening tasks.

Reactive Inhibitory Control Precedes Overt Stuttering Events

The paper investigates reactive inhibitory control preceding stuttered speech using MEG, finding increased beta power in R-preSMA associated with stuttering severity and trial outcomes.

No Evidence of Altered Language Laterality in People Who Stutter across Different Brain Imaging Studies of Speech and Language

This study examines language lateralization in people who stutter using fMRI and finds no evidence of altered lateralization compared to typically fluent speakers.

Neural oscillatory activity and connectivity in children who stutter during a non-speech motor task

This study examines neural oscillatory activity and connectivity in children who stutter during a non-speech motor task, finding reduced left hemisphere modulation and altered interhemispheric connectivity.

Fluency shaping increases integration of the command-to-execution and the auditory-to-motor pathways in persistent developmental stuttering

This study shows that fluency-shaping therapy increases neural connectivity in speech-related networks in individuals with persistent developmental stuttering.

The neural circuitry underlying the "rhythm effect" in stuttering

This study investigates how rhythmic speech affects neural activity in people who stutter, finding increased cerebellar connectivity during rhythmic speech.

Speech auditory-motor adaptation lacks an explicit component: reduced adaptation in adults who stutter reflects limitations in implicit sensorimotor learning.

This study investigates sensorimotor learning in adults who stutter (AWS) and finds that speech auditory-motor adaptation relies on implicit learning, which is impaired in AWS.

Two cortical representations of voice control are differentially involved in speech fluency

The paper compares structural networks of ventral and dorsal laryngeal motor cortex in individuals who stutter with and without intervention, finding differences in connectivity and intervention effects.

Dissociated development of speech and limb sensorimotor learning in stuttering: speech auditory-motor learning is impaired in both children and adults who stutter

This study shows that speech auditory-motor learning is impaired in both children and adults who stutter, with more severe deficits in children.

Linking lysosomal enzyme targeting genes and energy metabolism with altered gray matter volume in children with persistent stuttering

The paper investigates the relationship between genetic factors and brain structure in children with persistent stuttering, finding spatial correlations between gene expression and gray matter volume differences.

Transcranial direct current stimulation over left inferior frontal cortex improves speech fluency in adults who stutter

This study investigates whether tDCS over left inferior frontal cortex combined with speech fluency training improves speech fluency in adults who stutter, finding significant improvements at 1 week post-intervention.
