Dietary retinoic acid affects song maturation and gene expression in the song system of the zebra finch.

30 Aug 2008 Vitamin A, an essential nutrient, is required in its acidic form (retinoic acid) for normal embryogenesis and neuronal development, typically within well-defined concentration ranges. In zebra finches, a songbird species, localized retinoic acid ... Read more...

Functional identification of sensory mechanisms required for developmental song learning.

4 Apr 2008 A young male zebra finch (Taeniopygia guttata) learns to sing by copying the vocalizations of an older tutor in a process that parallels human speech acquisition. Brain pathways that control song production are well defined, but little is known ... Read more...

Role of the midbrain dopaminergic system in modulation of vocal brain activation by social context.

30 May 2007 In a well-studied model of social behaviour, male zebra finches sing directed song to court females and undirected song, used possibly for practice or advertisement. Although the two song types are similar, the level of neural activity and ... Read more...

Technical information about 'High Vocal Center'

Definition: Nucleus in the NEOSTRIATUM of bird brains that sends signals for song production and receives auditory input. In some adult SONGBIRDS, research has shown that the size of this nucleus changes seasonally and that it exhibits neurogenesis.
