Acetylcholine acts on songbird premotor circuitry to invigorate vocal output
eLife, 2020 Acetylcholine is well-understood to enhance cortical sensory responses and perceptual sensitivity in aroused or attentive states. Yet little is known about cholinergic influences on motor cortical regions.

Local field potentials in a pre-motor region predict learned vocal sequences.
PLoS Computational Biology, 2021 Neuronal activity within the premotor region HVC is tightly synchronized to, and crucial for, the articulate production of learned song in birds. Characterizations of this neural activity detail patterns of sequential bursting in small, carefully ...

Perineuronal nets in HVC and plasticity in male canary song [PDF]
PLOS 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
MedEdPORTAL, 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
Biology, 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 ...

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

A New Look at T Tauri Star Forbidden Lines: MHD Driven Winds from the Inner Disk [PDF]
, 2018 Magnetohydrodynamic (MHD) and photoevaporative winds are thought to play an important role in the evolution and dispersal of planet-forming disks. We report the first high-resolution ($\Delta v\sim$6\kms) analysis of [S II] $\lambda$4068, [O I] $\lambda ...

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

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