Hippocampal lesions impair spatial memory performance, but not song--a developmental study of independent memory systems in the zebra finch.

29 Jun 2009 Songbirds demonstrate song- and spatial-learning, forms of memory that appear distinct in formal characteristics and fitting the descriptions and criteria of procedural and episodic-like memory function, respectively. As in other vertebrates, the ... Read more...

Developmental origins of mosaic brain evolution: Morphometric analysis of the developing zebra finch brain.

8 May 2009 In adult zebra finches (Taeniopygia guttata), the telencephalon occupies 64% of the entire brain. This fraction is similar to what is seen in parrots, but many other birds possess a significantly smaller telencephalon. The aim of the present study ... Read more...

Presence of aromatase and estrogen receptor alpha in the inner ear of zebra finches.

May 2009 Sex differences in song behavior and in the neural system controlling song in songbirds are well documented but relatively little is known about sex differences in hearing. We recently demonstrated the existence of sex differences in auditory ... Read more...
