Purpose: The purpose of this study was to investigate cortical tracking speech (CTS) in adults who stutter (AWS) compared typically fluent (TFAs) test the involvement speech-motor network rhythmic information. Method: Participants' electroencephalogram recorded while they simply listened sentences (listening only) or completed them by naming a picture for speaking), thus manipulating upcoming production. We analyzed speech–brain coherence and brain connectivity during listening. Results: During listening-for-speaking task, AWS exhibited reduced CTS 3- 5-Hz range (theta), corresponding syllabic rhythm. effect localized left inferior parietal right pre/supplementary motor regions. Connectivity analyses revealed that TFAs had stronger information transfer theta both tasks fronto-temporo-parietal When considering whole sample participants, increased from superior temporal cortex sensorimotor correlated with faster times task. Conclusions: Atypical functioning stuttering impacts perception, especially situations requiring articulatory alertness. frontal (pre)motor regions is highlighted. Further investigation needed into perception individuals deficits, when smooth transitioning between listening speaking required, such as real-life conversational settings.

Speech disorders encompass a complex interplay of neuroanatomical, genetic, and environmental factors affecting individuals’ communication ability. This review synthesizes current insights into the neuroanatomy, genetic underpinnings, influences contributing to speech disorders. Neuroanatomical structures, such as Broca’s area, Wernicke’s arcuate fasciculus, basal ganglia, along with their connectivity, play critical roles in production, comprehension, motor coordination. Advances understanding intricate brain networks involved language offer typical development pathophysiology Genetic studies have identified key genes neural migration synaptic further elucidating role mutations disorders, stuttering sound Beyond biological mechanisms, this explores profound impact psychological factors, including anxiety, depression, neurodevelopmental conditions, on individuals Psychosocial comorbidities often exacerbate complicating diagnosis treatment underscoring need for holistic approach managing these conditions. Future directions point toward leveraging testing, digital technologies, personalized therapies, alongside addressing psychosocial dimensions, improve outcomes comprehensive overview aims inform future research therapeutic advancements, particularly treating fluency like stuttering.

This paper presents an interpretation of stuttering behavior, based on the principles active inference framework. Stuttering is a neurodevelopmental disorder characterized by speech disfluencies such as repetitions, prolongations, and blocks. The inference, theory predictive processing sentient can be used to conceptualize disruption in perception-action cycling underlying production. proposed here posits that arises from aberrant sensory precision prediction error dynamics, inhibiting syllable initiation. Relevant this theory, two hypothesized mechanisms are proposed: (1) mistiming (2) excessive attentional focus. Both highlight role neural oscillations, error, hierarchical integration framework also explains contextual variability behaviors, including adaptation effects fluency-inducing conditions. Reframing synaptopathy integrates neurobiological, psychological, behavioral dimensions, suggesting disruptions precision-weighting mediated neuromodulatory systems. perspective provides unified account sets stage for innovative research therapeutic approaches.

Developmental stuttering (DS) is a neurodevelopmental speech-motor disorder characterized by symptoms such as blocks, repetitions, and prolongations. Persistent DS often has significant negative impact on quality of life, interventions for it have limited efficacy. Herein, we briefly review existing research the neurophysiological underpinnings -specifically, brain metabolic default mode/social-cognitive networks (DMN/SCN) anomalies- arguing that psychedelic compounds might be considered investigated (e.g., in randomized clinical trials) treatment DS. The neural background likely to heterogeneous, some contribution from genetically determinants deficiencies basal ganglia cortical regions are thought play role appearance symptoms, which possibly results cascade events contributing impairments execution. In persistent DS, difficulties speech linked series associated aspects social anxiety avoidance. this context, SCN DMN (also influencing fronto-parietal, somato-motor, attentional networks) may worsening dysfluencies. Interestingly, metabolism SCN/DMN connectivity can modified psychedelics, been shown improve evidence psychiatric conditions depression, post-traumatic stress disorder, etc.) with psychological constructs rumination anxiety, also tend present To date, while there no controlled trials effects psychedelics anecdotal suggests these agents beneficial its characteristics.
