FoxP2 expression in avian vocal learners and non-learners.
(J Neurosci, 2004-03-31)
Most vertebrates communicate acoustically, but few, among them humans, dolphins and
whales, bats, and three orders of birds, learn this trait. FOXP2 is the first gene
linked to human speech and has been the target of positive ...
Differential expression of glutamate receptors in avian neural pathways for learned vocalization.
(J Comp Neurol, 2004-08-09)
Learned vocalization, the substrate for human language, is a rare trait. It is found
in three distantly related groups of birds-parrots, hummingbirds, and songbirds. These
three groups contain cerebral vocal nuclei for learned ...
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 ...
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 ...
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 ...
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 ...
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 ...
Specialized motor-driven dusp1 expression in the song systems of multiple lineages of vocal learning birds.
(PLoS One, 2012)
Mechanisms for the evolution of convergent behavioral traits are largely unknown.
Vocal learning is one such trait that evolved multiple times and is necessary in humans
for the acquisition of spoken language. Among birds, ...
Rudimentary substrates for vocal learning in a suboscine.
(Nat Commun, 2013)
Vocal learning has evolved in only a few groups of mammals and birds. The key neuroanatomical
and behavioural links bridging vocal learners and non-learners are still unknown.
Here we show that a non-vocal-learning suboscine, ...
