Transcriptomic Signatures of Projection Class Neurons for Vocal Control
<p>Vocal learning is the ability to modify acoustic structure and syntax of vocalizations. This rare trait is thought to have independently evolved three times in birds and five times in mammals. Vocal learning species exhibit an underlying convergence in brain circuitry, including a direct, …

Cloning and Characterization of the Vasopressin-Oxytocin Neuropeptide Signaling System in the Vocal Control System of the Zebra Finch (Taeniopygia guttata)
… acquisition and maintenance can be well study in vocal learning birds. Here, in addition to reviewing the pertinent literature, I clone VTR1A, VTR1B, VTR2A, and OTR, as well as VP-neurophysin, OT-neurophysin, and CAMP Responsive Element Binding Protein 3 Like 1 (CREB3L1), a transcription factor …

Articulatory feature encoding and sensorimotor training for tactually supplemented speech reception by the hearing-impaired
… speechreading and providing sensory feedback for vocal control, tactile speech aids may substantially enhance speech communication abilities in the absence of useful hearing. Research for this thesis consisted of several lines of work. First, tactual detection and temporal order discrimination by …

Vocal Handedness: The Emergence of Lateralization at Fledging
… produce the majority of their song under the control of the left hemisphere/left syringeal half. Unilateral section of the left treacheosyringeal nerve results in near complete loss of song while right denervation affects only a subset of call elements. This strong asymmetry for the production …

Examining the Links Among Motor Symptoms in Hyperfunctional Voice Disorders, Auditory Discrimination, and Auditory-Motor Function
… reliability of assays of speech auditory-motor control between the domains of voice and articulation, and supported the use of a categorical measure of fundamental frequency (fo) adaptation employed in chapter 3. In chapter 2, we developed a protocol to assess volitional control of small changes …

Changes of voice production in artificial acoustic environments
… physiological features of the speaker such as vocal tract size and lung capacity. However, the regulation of these production systems is affected by the perception of the communication environment and auditory feedback. The current study examined the effects of room acoustics in an artificial …
