A molecular neuroethological approach for identifying and characterizing a cascade of behaviorally regulated genes.
(Proc Natl Acad Sci U S A, 2006-10-10)Songbirds have one of the most accessible neural systems for the study of brain mechanisms of behavior. However, neuroethological studies in songbirds have been limited by the lack of high-throughput molecular resources ... -
Assessing visual requirements for social context-dependent activation of the songbird song system.
(Proc Biol Sci, 2009-01-22)Social context has been shown to have a profound influence on brain activation in a wide range of vertebrate species. Best studied in songbirds, when males sing undirected song, the level of neural activity and expression ... -
Computational inference of neural information flow networks.
(PLoS Comput Biol, 2006-11-24)Determining how information flows along anatomical brain pathways is a fundamental requirement for understanding how animals perceive their environments, learn, and behave. Attempts to reveal such neural information flow ... -
Convergent transcriptional specializations in the brains of humans and song-learning birds.
(Science, 2014-12-12)Song-learning birds and humans share independently evolved similarities in brain pathways for vocal learning that are essential for song and speech and are not found in most other species. Comparisons of brain transcriptomes ... -
Core and region-enriched networks of behaviorally regulated genes and the singing genome.
(Science, 2014-12-12)Songbirds represent an important model organism for elucidating molecular mechanisms that link genes with complex behaviors, in part because they have discrete vocal learning circuits that have parallels with those that ... -
Different mechanisms are responsible for dishabituation of electrophysiological auditory responses to a change in acoustic identity than to a change in stimulus location.
(Neurobiol Learn Mem, 2013-11)Repeated exposure to an auditory stimulus leads to habituation of the electrophysiological and immediate-early-gene (IEG) expression response in the auditory system. A novel auditory stimulus reinstates this response in ... -
Dopamine receptors in a songbird brain.
(J Comp Neurol, 2010-03-15)Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song ... -
Early onset of deafening-induced song deterioration and differential requirements of the pallial-basal ganglia vocal pathway.
(Eur J Neurosci, 2008-12)Similar to humans, songbirds rely on auditory feedback to maintain the acoustic and sequence structure of adult learned vocalizations. When songbirds are deafened, the learned features of song, such as syllable structure ... -
How thermal challenges change gene regulation in the songbird brain and gonad: Implications for sexual selection in our changing world.
(Molecular ecology, 2022-07)In a rapidly warming world, exposure to high temperatures may impact fitness, but the gene regulatory mechanisms that link sublethal heat to sexually selected traits are not well understood, particularly in endothermic animals. ... -
Influence of visual background on discrimination of signal-relevant colours in zebra finches (Taeniopygia guttata).
(Proceedings. Biological sciences, 2022-06)Colour signals of many animals are surrounded by a high-contrast achromatic background, but little is known about the possible function of this arrangement. For both humans and non-human animals, the background colour surrounding ... -
Interspecies avian brain chimeras reveal that large brain size differences are influenced by cell-interdependent processes.
(PLoS One, 2012)Like humans, birds that exhibit vocal learning have relatively delayed telencephalon maturation, resulting in a disproportionately smaller brain prenatally but enlarged telencephalon in adulthood relative to vocal non-learning ... -
Listening in.
(Elife, 2015-10-21)Zebra finches communicate with each other in ways that are more complex than previously thought. -
Mammalian genes induce partially reprogrammed pluripotent stem cells in non-mammalian vertebrate and invertebrate species.
(Elife, 2013-09-03)Cells are fundamental units of life, but little is known about evolution of cell states. Induced pluripotent stem cells (iPSCs) are once differentiated cells that have been re-programmed to an embryonic stem cell-like state, ... -
Profiling of experience-regulated proteins in the songbird auditory forebrain using quantitative proteomics.
(Eur J Neurosci, 2008-03)Auditory and perceptual processing of songs are required for a number of behaviors in songbirds such as vocal learning, territorial defense, mate selection and individual recognition. These neural processes are accompanied ... -
Role of the midbrain dopaminergic system in modulation of vocal brain activation by social context.
(Eur J Neurosci, 2007-06)In a well-studied model of social behaviour, male zebra finches sing directed song to court females and undirected song, used possibly for practice or advertisement. Although the two song types are similar, the level of ... -
Social context-dependent singing-regulated dopamine.
(J Neurosci, 2006-08-30)Like the mammalian striatum, the songbird striatum receives dense dopaminergic input from the midbrain ventral tegmental area-substantia nigra pars compacta complex. The songbird striatum also contains a unique vocal nucleus, ... -
The genome of a songbird.
(Nature, 2010-04-01)The zebra finch is an important model organism in several fields with unique relevance to human neuroscience. Like other songbirds, the zebra finch communicates through learned vocalizations, an ability otherwise documented ... -
The pallial basal ganglia pathway modulates the behaviorally driven gene expression of the motor pathway.
(Eur J Neurosci, 2007-04)The discrete neural network for songbird vocal communication provides an effective system to study neural mechanisms of learned motor behaviors in vertebrates. This system consists of two pathways--a vocal motor pathway ...
