Global View of the Functional Molecular Organization of the Avian Cerebrum: Mirror Images and Functional Columns
(JOURNAL OF COMPARATIVE NEUROLOGY, 2013-11)
Comparative genomics reveals insights into avian genome evolution and adaptation
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 ...
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.
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 ...
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 ...
Molecular mapping of movement-associated areas in the avian brain: a motor theory for vocal learning origin.
(PLoS One, 2008-03-12)
Vocal learning is a critical behavioral substrate for spoken human language. It is a rare trait found in three distantly related groups of birds-songbirds, hummingbirds, and parrots. These avian groups have remarkably similar ...
Global view of the functional molecular organization of the avian cerebrum: mirror images and functional columns.
(J Comp Neurol, 2013-11)
Based on quantitative cluster analyses of 52 constitutively expressed or behaviorally regulated genes in 23 brain regions, we present a global view of telencephalic organization of birds. The patterns of constitutively expressed ...
The dusp1 immediate early gene is regulated by natural stimuli predominantly in sensory input neurons.
(J Comp Neurol, 2010-07-15)
Many immediate early genes (IEGs) have activity-dependent induction in a subset of brain subdivisions or neuron types. However, none have been reported yet with regulation specific to thalamic-recipient sensory neurons of ...
Comparative genomics reveals insights into avian genome evolution and adaptation.
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. ...
