Neural Dynamics in the Basal Ganglia Underlying Birdsong Practice and Performance
<p>Skilled movements are typically more variable during practice, promoting exploration, yet highly stereotyped during performance, favoring exploitation. How neurons encode and dynamically regulate motor variability across practice and performance states remains unknown. Songbirds sing more …

Development of diffusive optical imaging as a tool for studying the neurobiology of birdsong
… it to record responses to presentations of birdsong in isoflurane-anesthetized zebra finches. We discovered a subtle but significant difference between the hemoglobin spectra of zebra finches and mammals which has a major impact in how hemodynamic responses are interpreted in the zebra …

Bird song as a basis for new techniques and improvisational practice with the baroque flute
… focussed on a critical and analytical study of birdsong. Birdsong offers a degree of pitch and timbral variation of phenomenal power. My research questioned and interrogated the structure; modes of delivery and sonorities in birdsong because I wanted to devise a new method of playing that might …

Graduate Recital, Flute
This recital explores works for flute inspired by birdsong. The flute's range and flexibility make the instrument a match for the avian syrinx. Vivaldi's Concerto in D Major presents a bird that bursts into refined song for the listener's pleasure. This showpiece depicts a captive pet at once caged …

Response Modulation by Single Units in the Auditory Neostriatum of Songbirds: Characterization of Responses and Their Relationships to Nuclear Gene Regulation in Adult and Juvenile Zebra Finches
"Presentation of birdsong activates immediate early gene (IEG) expression in the caudomedial neostriatum (NCM) of songbirds that are at least 30 days of age (d30) (Mello, et al., 1992; Jin & Clayton, 1997). However, when songbirds are raised in isolation, playback of birdsong fails to induce these …

Effects of Embodiment on Perceptual and Affective Responses to Infant Crying
… participants were played both infant crying and birdsong while exposed to similar embodied manipulations, including activation of muscles related to approach and withdrawal behavior. There were no embodied effects for ratings of crying or for affect. Comparing Study 1 and 2, there was no change …

The Ups and Downs of MAP Kinase ERK: Modulation of Molecular Responses to Song in the Zebra Finch Auditory Forebrain
… the familiarity and significance of a specific birdsong stimulus. Moreover, ERK activation appears to be necessary, but perhaps not sufficient, for triggering of an IEG response to song presentation. Thus ERK has a central role in connecting behavioral and perceptual experience to genomic …

Singing Bird Singing Soul: Avian Symbolism in Cross-Cultural Soprano Repertoire
… sopranos. Understanding the musical depiction of birdsong and avian behavior in these pieces allows singers to achieve greater expressive depth and a more nuanced emotional interpretation in performance.

From Psychology to Phylogeny: Bridging Levels of Analysis in Cultural Evolution
… research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and …

Effects of Language Dominance in Spanish-English Bilingual Speakers
… regarding language use, attitudes, and fluency (Birdsong, Gertken, & Amengual, 2012). Spanish-English bilingual participants and monolingual English-speaking participants (n=20) then rated a series of translationally equivalent nouns (n=80) according to sound, color, morality, valence, size, and …

Expression of GABAA receptor subunit genes in the avian song system and their role in learning and memory
… systems and there are striking parallels between birdsong and speech production in humans hence the fundamental neuronal mechanisms are similar. Despite major developments towards understanding the anatomical and electrophysiological properties of various song-system nuclei, the nature of the …

Organisation des bilingualen Gehirns : eine EEG-Studie zum Einfluss von Erwerbsalter und Sprachniveau
… the second language acquisition research (e.g. Birdsong, 1999). Studies using brain imaging techniques as well as electrophysiological studies provide inhomogeneous findings of the brain organization of first and second language (e.g. Indefrey, 2006). The most discussed factors that influence …

Nuair a bha Gaidhlig aig na h-eoin : an investigation into the art and artifice of avifaunal mimesis as a mode of artistic expression in Gaelic oral culture from the seventeenth century to the present
… of a primary sound object (in this instance birdsong) or alternatively the figurative imitation of a given image implied by the use of metaphor. To this end, the present study will be divided into three sections, delineated in terms of genre. Chapters one and three will address the faculty of …

NEURAL BASIS OF PERFORMANCE EVALUATION IN BIRDS
… for learning a motor sequence such as birdsong? Here I introduce work in the songbird zebra finch demonstrating RL applies to performance learning based on a flexible internal benchmark. Dopaminergic neurons in the midbrain were shown to report a performance prediction error. I expand …

Is It Memory or Is It Death? Caspase-3 and Memory Formation
… learning experience---hearing the sound of birdsong---triggers a brief increase in active caspase-3 in the auditory forebrain of adult male zebra finches that does not lead to cell death. Active caspase-3 is detected within 2 min of stimulation, peaks at 10 min, and is gone by 20 min. …

Comparative Mitochondrial DNA Sequence Diversity in Isolated and Open Populations of Southern Flying Squirrels
Three populations of Southern flying squirrels were studied in the Ouachita Mountains of Arkansas to assess the impact of population subdivision-due to island formation--on the population genetics of Glaucomys volans. One island, one mainland, and one open population were investigated. A 367 …

Analysis of Immediate-Early Gene Expression in the Songbird Brain Following Song Presentation
… a strong depolarizing agent, and playbacks of birdsong, a natural stimulus of well-defined behavioral relevance. Both stimuli result in significant increases in ZENK mRNA levels in the brain. Metrazole experiments demonstrate that ZENK is differentially regulated and may be selectively …

Syntactic focus structure processing : behavioral and electrophysiological evidence from L1 and L2 French
… language acquisition (e.g. Newport, 1990; cf. Birdsong & Molis, 2001). The results of this experiment are interpreted as evidence against the presence of a critical period for the acquisition of information structure in a second language. In Experiment 2, L2 learners in low- and …
