title: The genomics of memory and learning in songbirds.
abstract: Songbirds have unique value as a model for memory and learning. In their natural social life, they communicate through vocalizations that they must learn to produce and recognize. Song communication elicits abrupt changes in gene expression in regions of the forebrain responsible for song perception and production--what is the functional significance of this genomic response? For 20 years, the focus of research was on just a few genes [primarily ZENK, now known as egr1 (early gene response 1)]. Recently, however, DNA microarrays have been developed and applied to songbird behavioral research, and in 2010 the initial draft assembly of the zebra finch genome was published. Together, these new data reveal that the genomic involvement in song processing is far more complex than anticipated. The concepts of neurogenomic computation and biological embedding are introduced as frameworks for future research.
