Vocal cord paralysis (VCP) may be caused by a variety of mediastinal disease entities, including various neoplastic, inflammatory, and vascular conditions, and may be the presenting symptom of an otherwise clinically occult disease. Familiarity with the spectrum of thoracic diseases that can result in VCP and inclusion of the mediastinum to the level of the aorticopulmonary window (left side) o...

bilateral vocal cord paralysis is a rare and preventable complication of anterior cervical discectomy and fusion. herein, we report a fatal case of bilateral vocal cord paralysis after anterior cervical discectomy and fusion (acd/f). a 65-year-old man with cervical spine trauma and anterior cord syndrome, following car overturn presented to our emergency department. the patient had c6-t10 prola...

Individual axon arbors within developing neural circuits are remodeled during restricted sensitive periods, leading to the emergence of precise patterns of connectivity and specialized adaptive behaviors. In male zebra finches, the circuit connecting the medial dorsolateral nucleus of the thalamus (DLM) and its cortical target, the lateral magnocellular nucleus of the anterior neostriatum (lMAN...

Vocal signals such as calls play a crucial role for survival and successful reproduction, especially in group-living animals. However, call interactions and call dynamics within groups remain largely unexplored because their relation to relevant contexts or life-history stages could not be studied with individual-level resolution. Using on-bird microphone transmitters, we recorded the vocalisat...

A model of the vocal-tract area function is described that consists of four tiers. The first tier is a vowel substrate defined by a system of spatial eigenmodes and a neutral area function determined from MRI-based vocal-tract data. The input parameters to the first tier are coefficient values that, when multiplied by the appropriate eigenmode and added to the neutral area function, construct a...

Speech production is an important human function involving a set of organs with specific morphological and dynamic aspects. The inter-speaker variability, the coarticulation or the nasality are some interesting aspects to improve a realistic 3D modeling of the vocal tract. For this, the understanding of the mechanism of speech production is crucial, as the current image data is not sufficient t...

BACKGROUND In many songbirds the larger vocal repertoire of males is associated with sexual dimorphism of the vocal control centers and muscles of the vocal organ, the syrinx. However, it is largely unknown how these differences are translated into different acoustic behavior. METHODOLOGY/PRINCIPAL FINDINGS Here we show that the sound generating structures of the syrinx, the labia and the ass...

To understand how language influences the vocal communication of emotion, we investigated how discrete emotions are recognized and acoustically differentiated in four language contexts—English, German, Hindi, and Arabic. Vocal expressions of six emotions (anger, disgust, fear, sadness, happiness, pleasant surprise) and neutral expressions were elicited from four native speakers of each language...

OBJECTIVES/HYPOTHESIS This study was designed to assess the feasibility of the submucosal infusion technique combined with microflap dissection as a radical therapeutic and diagnostic option for precancerous laryngeal leukoplakia. STUDY DESIGN Retrospective study. METHODS Severe dysplasia or carcinoma in situ was diagnosed after phonomicrosurgical dissections in 25 patients with unilateral ...

BACKGROUND Maximum phonation times (MPT) of vowels in adult women with vocal nodules. AIM To verify and to correlate the values of MPT of vowels in young and middle-aged adult women with vocal nodules. METHOD Database records from a speech therapy school-clinic were used, making up a total of 38 subjects. INCLUSION CRITERIA female adults, aged between 20 and 53 years, with otorhinolaryngo...
