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 ...
Brain gene regulation by territorial singing behavior in freely ranging songbirds.
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. ...
Complex evolutionary trajectories of sex chromosomes across bird taxa.
Sex-specific chromosomes, like the W of most female birds and the Y of male mammals, usually have lost most genes owing to a lack of recombination. We analyze newly available genomes of 17 bird species representing the avian ...
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 ...
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. ...
Of mice, birds, and men: the mouse ultrasonic song system has some features similar to humans and song-learning birds.
(PLoS One, 2012)
Humans and song-learning birds communicate acoustically using learned vocalizations. The characteristic features of this social communication behavior include vocal control by forebrain motor areas, a direct cortical projection ...
