A framework for integrating the songbird brain.
(J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2002-12)Biological systems by default involve complex components with complex relationships. To decipher how biological systems work, we assume that one needs to integrate information over multiple levels of complexity. The songbird ... -
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 ... -
A relationship between behavior, neurotrophin expression, and new neuron survival.
(Proc Natl Acad Sci U S A, 2000-07-18)The high vocal center (HVC) controls song production in songbirds and sends a projection to the robust nucleus of the archistriatum (RA) of the descending vocal pathway. HVC receives new neurons in adulthood. Most of the ... -
Altered ultrasonic vocalization and impaired learning and memory in Angelman syndrome mouse model with a large maternal deletion from Ube3a to Gabrb3.
(PLoS One, 2010-08-20)Angelman syndrome (AS) is a neurobehavioral disorder associated with mental retardation, absence of language development, characteristic electroencephalography (EEG) abnormalities and epilepsy, happy disposition, movement ... -
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 ... -
Basal ganglia function, stuttering, sequencing, and repair in adult songbirds.
(Sci Rep, 2014-10-13)A pallial-basal-ganglia-thalamic-pallial loop in songbirds is involved in vocal motor learning. Damage to its basal ganglia part, Area X, in adult zebra finches has been noted to have no strong effects on song and its function ... -
Behavioural response to song and genetic divergence in two subspecies of white-crowned sparrows (Zonotrichia leucophrys).
(Molecular ecology, 2017-06)Divergence in sexual signals may drive reproductive isolation between lineages, but behavioural barriers can weaken in contact zones. Here, we investigate the role of song as a behavioural and genetic barrier in a contact ... -
Behaviourally driven gene expression reveals song nuclei in hummingbird brain.
(Nature, 2000-08-10)Hummingbirds have developed a wealth of intriguing features, such as backwards flight, ultraviolet vision, extremely high metabolic rates, nocturnal hibernation, high brain-to-body size ratio and a remarkable species-specific ... -
Bottlenose dolphins exchange signature whistles when meeting at sea.
(Proc Biol Sci, 2012-07-07)The bottlenose dolphin, Tursiops truncatus, is one of very few animals that, through vocal learning, can invent novel acoustic signals and copy whistles of conspecifics. Furthermore, receivers can extract identity information ... -
Brain evolution by brain pathway duplication.
(Philos Trans R Soc Lond B Biol Sci, 2015-12-19)Understanding the mechanisms of evolution of brain pathways for complex behaviours is still in its infancy. Making further advances requires a deeper understanding of brain homologies, novelties and analogies. It also requires ... -
Brain gene regulation by territorial singing behavior in freely ranging songbirds.
(Neuroreport, 1997-05-27)To investigate the ecological relevance of brain gene regulation associated with singing behavior in songbirds, we challenged freely ranging song sparrows with conspecific song playbacks within their breeding territories. ... -
Comparative genomics reveals insights into avian genome evolution and adaptation.
(Science, 2014-12-12)Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. ... -
Comparative genomics reveals molecular features unique to the songbird lineage.
(BMC Genomics, 2014-12-13)BACKGROUND: Songbirds (oscine Passeriformes) are among the most diverse and successful vertebrate groups, comprising almost half of all known bird species. Identifying the genomic innovations that might be associated with ... -
Convergent differential regulation of parvalbumin in the brains of vocal learners.
(PLoS One, 2012)Spoken language and learned song are complex communication behaviors found in only a few species, including humans and three groups of distantly related birds--songbirds, parrots, and hummingbirds. Despite their ... -
Convergent differential regulation of SLIT-ROBO axon guidance genes in the brains of vocal learners.
(J Comp Neurol, 2015-04-15)Only a few distantly related mammals and birds have the trait of complex vocal learning, which is the ability to imitate novel sounds. This ability is critical for speech acquisition and production in humans, and is attributed ... -
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 ... -
Core and Shell Song Systems Unique to the Parrot Brain.
(PLoS One, 2015)The ability to imitate complex sounds is rare, and among birds has been found only in parrots, songbirds, and hummingbirds. Parrots exhibit the most advanced vocal mimicry among non-human animals. A few studies have noted ... -
Corollary discharge circuits in the primate brain.
(Curr Opin Neurobiol, 2008-12)Movements are necessary to engage the world, but every movement results in sensorimotor ambiguity. Self-movements cause changes to sensory inflow as well as changes in the positions of objects relative to motor effectors ... -
Cultural conformity generates extremely stable traditions in bird song.
(Nature communications, 2018-06)Cultural traditions have been observed in a wide variety of animal species. It remains unclear, however, what is required for social learning to give rise to stable traditions: what level of precision and what learning strategies ...
