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 ...
Selective expression of insulin-like growth factor II in the songbird brain.
(J Neurosci, 1997-09-15)
Neuronal replacement occurs in the forebrain of juvenile and adult songbirds. To address
the molecular processes that govern this replacement, we cloned the zebra finch insulin-like
growth factor II (IGF-II) cDNA, a factor ...
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 ...
For whom the bird sings: context-dependent gene expression.
(Neuron, 1998-10)
Male zebra finches display two song behaviors: directed and undirected singing. The
two differ little in the vocalizations produced but greatly in how song is delivered.
"Directed" song is usually accompanied by a courtship ...
Brain gene regulation by territorial singing behavior in freely ranging songbirds.
(Neuroreport, 1997-05-27)
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. ...
Rapid behavioral and genomic responses to social opportunity.
(PLoS Biol, 2005-11)
From primates to bees, social status regulates reproduction. In the cichlid fish Astatotilapia
(Haplochromis) burtoni, subordinate males have reduced fertility and must become dominant
to reproduce. This increase in sexual ...
