Marmoset monkeys are known for their rich vocal repertoire. However, the underlying call production mechanisms remain unclear. By showing that marmoset moneys are capable of interrupting and modulating ongoing vocalizations, recent studies in marmoset monkeys challenged the decades-old concepts of primate vocal pattern generation that suggested that monkey calls consist of one discrete call pattern. The current article will present a revised version of the brainstem vocal pattern-generating network in marmoset monkeys that is capable of responding to perturbing auditory stimuli with rapid modulatory changes of the acoustic call structure during ongoing calls. These audio-vocal integration processes might potentially happen at both the cortical and subcortical brain level.

Predictive processing across hierarchically organized time scales is one of the fundamental principles of neural computations in the cerebral cortex. We hypothesize that relatively complex aggregation...
Considerable evidence has shown that experienced singers are capable of voluntarily suppressing vocal compensations for consistent pitch perturbations in auditory feedback. Our recent behavioral study...
The cerebellum has been implicated in the feedforward control of speech production. However, the role of the cerebellum in the feedback control of speech production remains unclear. To address this qu...
In adult animals, movement and vocalizations are coordinated, sometimes facilitating, and at other times inhibiting, each other. What is missing is how these different domains of motor control become ...
We present a new computational model of speech motor control: the Feedback-Aware Control of Tasks in Speech or FACTS model. FACTS employs a hierarchical state feedback control architecture to control ...
This first study will enroll 3 groups of patients with vocal fold nodules that will receive different schedules of ambulatory voice biofeedback (100% frequency feedback, 25% frequency feed...
The purpose of this preliminary study is to help clarify our hypotheses for the longitudinal study by investigating the relationship between vocal cord paralysis and central auditory proce...
Although altered biomechanics has been well documented as an impairment associated with chronic ankle instability (CAI), effective interventions targeting biomechanics with long-term outco...
Respiratory function, phonation and facial expressivity are related to emotional reaction through neurophysiological process. Specific emotional respiratory, vocal and facial patterns had ...
The goal of the study is to examine the cortical activity during speech perception and speech production in idiopathic stutterers compared to fluent speakers. Therefore, the noninvasive m...
A mechanism of communication with a physiological system for homeostasis, adaptation, etc. Physiological feedback is mediated through extensive feedback mechanisms that use physiological cues as feedback loop signals to control other systems.
A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.
An auditory brainstem structure in the pontine tegmentum that contains several nuclei associated with auditory localization and is component of ascending and descending auditory pathways.
Disorders of hearing or auditory perception due to pathological processes of the AUDITORY PATHWAYS in the CENTRAL NERVOUS SYSTEM. These include CENTRAL HEARING LOSS and AUDITORY PERCEPTUAL DISORDERS.
Nucleus in the NEOSTRIATUM of bird brains that sends signals for song production and receives auditory input. In some adult SONGBIRDS, research has shown that the size of this nucleus changes seasonally and that it exhibits neurogenesis.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
