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...

Activities of 3beta-HSD and aromatase in slices of developing and adult zebra finch brain.

19 Aug 2006 Sex steroids influence the development and function of the songbird brain. Developmentally, the neural circuitry underlying song undergoes masculine differentiation under the influence of estradiol. In adults, estradiol stimulates song behavior and ... Read more...

Acetylcholinesterase in central vocal control nuclei of the zebra finch (Taeniopygia guttata).

30 May 2004 The distribution of acetylcholinesterase (AChE) in the central vocal control nuclei of the zebra finch was studied using enzyme histochemistry. AChE fibres and cells are intensely labelled in the forebrain nucleus area X, strongly labelled in high ... 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.
