Perineuronal nets in HVC and plasticity in male canary song [PDF]

open access: yesPLOS ONE, 2021
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.

Teaching and Evaluating High-Value Care Through a Novel Case-Based Morning Report Curriculum

open access: yesMedEdPORTAL, 2016
Introduction It's the responsibility of medical educators to train residents to be responsible stewards of finite health care resources. Thus, we developed an interactive morning report curriculum that focuses on high-value care (HVC) decision making ...

Striatal Injury Induces Overall Brain Alteration at the Pallial, Thalamic, and Cerebellar Levels

open access: yesBiology, 2022
The striatal region Area X plays an important role during song learning, sequencing, and variability in songbirds. A previous study revealed that neurotoxic damage within Area X results in micro and macrostructural changes across the entire brain ...

A Faculty Development Workshop for High-Value Care Education Across Clinical Settings

open access: yesMedEdPORTAL, 2018
Introduction Despite rising health care costs, trainees frequently do not receive formal high-value care (HVC) training. As medical education often occurs through informal learning, it is imperative that medical educators be prepared to teach HVC ...

Influence of testosterone metabolites on song-control system neuroplasticity during photostimulation in adult European starlings (Sturnus vulgaris). [PDF]

open access: yesPLoS ONE, 2012
The song-control system is a network of discrete nuclei in the songbird brain that controls the production and learning of birdsong and exhibits some of the best-studied neuroplasticity found in the adult brain.

HVCs, infall and the Galactic Fountain [PDF]

open access: yesProceedings of the International Astronomical Union, 2012
AbstractHigh-velocity clouds (HVCs) consist of gas that does not take part in normal Galactic rotation, having velocities deviating by up to 400 km s−1 from those expected from rotation. Over the past five decades, studies have shown they these clouds trace a number of different processes, including the Galactic Fountain, tidal streams, and infall ...

EM connectomics reveals axonal target variation in a sequence-generating network

open access: yeseLife, 2017
The sequential activation of neurons has been observed in various areas of the brain, but in no case is the underlying network structure well understood.

Control of vocal and respiratory patterns in birdsong: dissection of forebrain and brainstem mechanisms using temperature. [PDF]

open access: yesPLoS ONE, 2011
Learned motor behaviors require descending forebrain control to be coordinated with midbrain and brainstem motor systems. In songbirds, such as the zebra finch, regular breathing is controlled by brainstem centers, but when the adult songbird begins to ...

Caught in the Act: A Metal-rich High-velocity Cloud in the Inner Galaxy

open access: yesThe Astrophysical Journal, 2023
We characterize the chemical and physical conditions in an outflowing high-velocity cloud (HVC) in the inner Galaxy. We report a supersolar metallicity of [O/H] = +0.36 ± 0.12 for the HVC at v _LSR = 125.6 km s ^−1 toward the star HD 156359 ( l = 328.°7,

Infall of HVC's and the Origin of HI Supershells [PDF]

open access: yesSymposium - International Astronomical Union, 1991
Surveys for atomic hydrogen at very high velocities (|V| ≥ 140 km s–1) in the galactic center and anticenter regions of the sky reveal a net inflow of gas toward the Milky Way. In the anticenter, the collisions of infalling clouds with galactic material trigger the most energetic structural disturbance in the Galaxy, the “anticenter supershell”.
