Comprehension of narratives constitutes a fundamental part of our everyday life experience. Although the neural mechanism of auditory narrative comprehension has been investigated in some studies, the neural correlates underlying this mechanism and its heritability remain poorly understood. We investigated comprehension of naturalistic speech in a large, healthy adult population (n = 429; 176/253 M/F; 22-36 years of age) consisting of 192 twin pairs (49 monozygotic and 47 dizygotic pairs) and 237 of their siblings...

PURPOSE: We combined a large longitudinal neuroimaging dataset that includes children who do and do not stutter and a whole-brain network analysis in order to examine the intra- and inter-network connectivity changes associated with stuttering. Additionally, we asked whether whole brain connectivity patterns observed at the initial year of scanning could predict persistent stuttering in later years. METHODS: A total of 224 high-quality resting state fMRI scans collected from 84 children (42 stuttering, 42 controls) were entered into an independent component analysis (ICA), yielding a number of distinct network connectivity maps ("components") as well as expression scores for each component that quantified the degree to which it is expressed for each child...

To obtain further evidence that action observation can serve as a proxy for action execution and planning in posterior parietal cortex, we scanned participants while they were (1) observing two classes of action: vocal communication and oral manipulation, which share the same effector but differ in nature, and (2) rehearsing and listening to nonsense sentences to localize area Spt, thought to be involved in audio-motor transformation during speech. Using this localizer, we found that Spt is specifically activated by vocal communication, indicating that Spt is not only involved in planning speech but also in observing vocal communication actions...

OBJECTIVE: To identify inherited or de novo mutations associated with a suite of neurodevelopmental abnormalities in a 10-year-old patient displaying ataxia, motor and speech delay, and intellectual disability. METHODS: We performed whole-exome sequencing of the proband and her parents. A pathogenic gene variant was identified as damaging based on sequence conservation, gene function, and association with disorders having similar phenotypic profiles. Functional characterization of the mutated protein was performed in vitro using a heterologous expression system...

Comparisons of musicians and non-musicians have revealed enhanced cognitive and sensory processing in musicians, with longitudinal studies suggesting these enhancements may be due in part to experience-based plasticity. Here, we investigate the impact of primary instrument on the musician signature of expertise by assessing three groups of young adults: percussionists, vocalists, and non-musician controls. We hypothesize that primary instrument engenders selective enhancements reflecting the most salient acoustic features to that instrument, whereas cognitive functions are enhanced regardless of instrument...

The study of language network plasticity following left hemisphere stroke is foundational to the understanding of aphasia recovery and neural plasticity in general. Damage in different language nodes may influence whether local plasticity is possible and whether right hemisphere recruitment is beneficial. However, the relationships of both lesion size and location to patterns of remapping are poorly understood. In the context of a picture naming fMRI task, we tested whether lesion size and location relate to activity in surviving left hemisphere language nodes, as well as homotopic activity in the right hemisphere during covert name retrieval and overt name production...

ALS is a multisystem disorder affecting cognitive and motor functions. Bulbar-onset ALS (bALS) may be preferentially associated with language/cognitive impairments, compared with spinal-onset ALS (sALS), stemming from a potentially unique neuropathology. The objective of this systematic review was to compare neuropathology reported for bALS and sALS subtypes in studies of cadaveric brains. Using Cochrane guidelines, we reviewed articles in MEDLINE, Embase, and PsycINFO databases using standardized search terms for ALS and neuropathology, from inception until July 16th 2016...

INTRODUCTION: Surgical resection in premotor areas can lead to supplementary motor area syndrome as well as a permanent deficit. However, recent findings suggest a putative role of the negative motor network in those dysfunctions. Our objective was to compare the functional results in two groups of adult patients who underwent the resection of a frontal glioma with and without resection of the negative motor networks. MATERIAL AND METHODS: Twelve patients (total of 13 surgeries) were selected for awake surgery for a frontal glioma...

Introduction This study compared the differences in recorded speech variables between people treated with conventional 'in person' Lee Silverman Voice Treatment (LSVT) and those treated remotely via iPad-based 'Facetime'. Method Eight participants were selected for the iPad LSVT, and 21 similarly matched subjects were selected from existing data to form the 'in person' group. Participants in both groups had diagnosed idiopathic Parkinson's disease and moderate hypokinetic dysarthria. Eighteen sessions of prescribed LSVT comprising a pre-treatment assessment, 16 treatment sessions, and a six months' post-treatment assessment were administered for each person...

: Neuromuscular electrical stimulation (NMES) may have potential as a treatment for muscle weakness as it may improve strength when applied to the orofacial muscles. However, before incorporating this procedure into clinical practice, research is needed to investigate its effects on lingual and facial muscles of speech and mastication. The aim of this study was to determine what effect(s) submental and labial NMES would have on lingual and labial muscle strength in healthy participants...

OBJECTIVES: As neonatal care is being scaled up in economically poor settings, there is a need to know more on post-hospital discharge and longer-term outcomes. Of particular interest are mortality, prevalence of developmental impairments and malnutrition, all known to be worse in low-birth-weight neonates (LBW, <2500 grams). Getting a better handle on these parameters might justify and guide support interventions. Two years after hospital discharge, we thus assessed: mortality, developmental impairments, and nutritional status of LBW children...

Action recognition has been found to rely not only on sensory brain areas but also partly on the observer's motor system. However, whether distinct auditory and visual experiences of an action modulate sensorimotor activity remains largely unknown. In the present sparse sampling fMRI study, we determined to which extent sensory and motor representations interact during the perception of tongue and lip speech actions. Tongue and lip speech actions were selected because tongue movements of our interlocutor are accessible via their impact on speech acoustics but not visible because of its position inside the vocal tract, whereas lip movements are both "audible" and visible...

BACKGROUND The human face is a one-of-a-kind structure with unique morphology, complexity, and function, in which different subunits are not even similar to other parts of the body. Therefore, extended complex deficits of the face are usually difficult to reconstruct, and autologous tissue restoration is generally not able to give a satisfactory aesthetic and functional outcome. The main goal of face allotransplantation is to restore symmetry, contour, and appearance as well as function of the face, especially control of orbicularis oculi and oris muscle physiology...

Speakers respond automatically and rapidly to compensate for brief perturbations of pitch in their auditory feedback. The specific adjustments in vocal output require integration of brain regions involved in speech-motor-control in order to detect the sensory-feedback error and implement the motor correction. Cortical regions involved in the pitch reflex phenomenon are highly vulnerable targets of network disruption in Alzheimer's disease (AD). We examined the pitch reflex in AD patients (n = 19) compared to an age-matched control group (n = 16)...

BACKGROUND: Until now, there has been no comprehensive long-term study in Germany on the development of extremely premature infants up to school age. METHODS: From October 2004 to September 2008, in the German federal state of Lower Saxony, 437 infants born at a gestational age less than 28 weeks were followed up at the ages of 2 and 5 years, and some at the age of 10 years. The 5-year follow-up data were collated with the peri- and neonatological parameters and compared with the 2- and 10-year follow-up data...

The aim of the study was to investigate how adults with 22q11.2 deletion syndrome (22q11DS) performed on dysarthria and intelligibility tests compared with a control group. Ten participants with confirmed 22q11.2 deletion, five males and five females with a mean age of 31 years (range: 19-49), were compared with a control group matched for gender and age (five males and five females, mean age: 32 years, range: 19-49). Assessment of non-verbal and verbal tasks reflecting respiration, phonation, oral motor function, velopharyngeal function, articulation, and prosody was performed as well as the Swedish Test of Intelligibility (STI)...
