For whom the bird sings: context-dependent gene expression.
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 ...
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 ...
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 ...
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 ...
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, ...
