Examining resting state functional connectivity and frequency power analysis in adults who stutter compared to adults who do not stutter.

Introduction: Stuttering is a speech disorder characterized by impaired connections between brain regions involved in speech production. This study aimed to investigate functional connectivity and frequency power during rest in adults who stutter (AWS) compared to fluent adults (AWNS) in the dorsolateral prefrontal cortex (DLPFC), dorsolateral frontal cortex (DLFC), supplementary motor area (SMA), motor speech, angular gyrus (AG), and inferior temporal gyrus (ITG).

Materials And Methods: Fifteen AWS (3 females, 12 males) and fifteen age- and sex-matched AWNS (3 females, 12 males) participated in this study.

Vocal Tract Discomforts among Smokers.

Introduction: Smoking is a dangerous behavior for the human body and the vocal tract. Smoking can cause several laryngeal and vocal tract symptoms in smokers. One of these symptoms can be physical discomfort experienced by this population.

A comparison of the performance of Persian speaking children who do and do not stutter on three nonwords repetition tasks.

Purpose: The purpose of the study was to examine the performance of Persian speaking children who stutter (CWS) and children who do not stutter (CWNS) on three nonword repetition tasks, while also focusing on which task and scoring method best differentiates the two groups of children.

Method: Thirty CWS and 30 CWNS between the ages of 5;0 to 6;6 completed three nonword repetition tasks that varied in complexity. Each task was scored using two methods: nonwords correct and phonemes correct.
