Frontiers in Neuroscience, 2021 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 ...

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

Model of the songbird nucleus HVC as a network of central pattern generators [PDF]
Journal of Neurophysiology, 2016 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)

Model of the HVC neural network as a song motor in zebra finch
Frontiers in Computational NeuroscienceThe 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

Emergency Medicine Resident Needs Assessment and Preferences for a High-value Care Curriculum
Western Journal of Emergency Medicine, 2023 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 ...

Distance and Metallicity of HVCS [PDF]
Symposium - International Astronomical Union, 1996 Table 1 summarizes results of programs to determine distances and metallicities of high-velocity clouds (HVCs, see Wakker 1991, IAU Symp 144, 27 for a general review). Reliable absorption is reported for one stellar probe (BD+38 2182), giving a distance D<5kpc for complex M. Other results are controversial (BT Dra), uncertain(HD 135485) or atypical (

Characterization of synaptically connected nuclei in a potential sensorimotor feedback pathway in the zebra finch song system. [PDF]
PLoS ONE, 2012 Birdsong is a learned behavior that is controlled by a group of identified nuclei, known collectively as the song system. The cortical nucleus HVC (used as a proper name) is a focal point of many investigations as it is necessary for song production ...

Scientific Reports, 2022 Whilst the majority of the literature suggests that balloon kyphoplasty (BKP) can relieve pain associated with vertebral compression fractures (VCFs), evidence of high-viscosity cement (HVC) vertebroplasty (VP) or low viscosity cement (LVC) BKP for the ...

Sexual differences in cell proliferation in the ventricular zone, cell migration and differentiation in the HVC of juvenile Bengalese finch. [PDF]
PLoS ONE, 2014 Song control nuclei have distinct sexual differences and thus are an ideal model to address how brain areas are sexually differentiated. Through a combination of histological analysis and electrical lesions, we first identified the ventricle site for HVC
