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 ...
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 ...
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 ...
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 ...
Molecular mapping of brain areas involved in parrot vocal communication.
(J Comp Neurol, 2000-03-27)
Auditory and vocal regulation of gene expression occurs in separate discrete regions of the songbird brain. Here we demonstrate that regulated gene expression also occurs during vocal communication in a parrot, belonging ...
Site-specific retinoic acid production in the brain of adult songbirds.
The song system of songbirds, a set of brain nuclei necessary for song learning and production, has distinctive morphological and functional properties. Utilizing differential display, we searched for molecular components ...
