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 ...
The genome of a songbird.
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 ...
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 ...
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 ...
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 ...
