Model of the HVC neural network as a song motor in zebra finch [PDF]
The nucleus HVC within the avian song system produces crystalized instructions which lead to precise, learned vocalization in zebra finches (Taeniopygia guttata). This paper proposes a model of the HVC neural network based on the physiological properties

Variable and slow-paced neural dynamics in HVC underlie plastic song production in juvenile zebra finches [PDF]
Zebra finches undergo a gradual refinement of their vocalizations, transitioning from variable juvenile songs to the stereotyped song of adulthood.

Seasonal changes in patterns of gene expression in avian song control brain regions. [PDF]
Photoperiod and hormonal cues drive dramatic seasonal changes in structure and function of the avian song control system. Little is known, however, about the patterns of gene expression associated with seasonal changes.

Biophysical network modeling of temporal and stereotyped sequence propagation of neural activity in the premotor nucleus HVC [PDF]
Stereotyped neural sequences are often exhibited in the brain, yet the neurophysiological mechanisms underlying their generation are not fully understood.

Singing occurs in songbirds of both sexes, but some species show typical degrees of sex-specific performance. We studied the transcriptional sex differences in the HVC, a brain nucleus critical for song pattern generation, of the forest weaver (Ploceus ...

Hemispheric dominance in HVC is experience-dependent in juvenile male zebra finches
Juvenile male zebra finches (Taeniopygia guttata) must be exposed to an adult tutor during a sensitive period to develop normal adult song. The pre-motor nucleus HVC (acronym used as a proper name), plays a critical role in song learning and production ...

Perineuronal nets in HVC and plasticity in male canary song [PDF]
Abstract Songbirds learn their vocalizations during developmental sensitive periods of song memorization and sensorimotor learning. Some seasonal songbirds, called open-ended learners, recapitulate transitions from sensorimotor learning and song crystallization on a seasonal basis during adulthood.

Model of the songbird nucleus HVC as a network of central pattern generators [PDF]
We propose a functional architecture of the adult songbird nucleus HVC in which the core element is a “functional syllable unit” (FSU). In this model, HVC is organized into FSUs, each of which provides the basis for the production of one syllable in vocalization. Within each FSU, the inhibitory neuron population takes one of two operational states: 1)

Emergency Medicine Resident Needs Assessment and Preferences for a High-value Care Curriculum
Introduction: Consideration of the cost of care and value in healthcare is now a recognized element of physician training. Despite the urgency to educate trainees in high-value care (HVC), educational curricula and evaluation of these training paths ...
