Whenever it hears an unfamiliar song from a male of the same species, the zebra finch stops chirping, hopping and grooming. It listens attentively for minutes at a time, occasionally cocking its head but otherwise immobile. Once it becomes familiar with the song, it goes back to its busy routine. In a new study, researchers discovered that levels of microRNAs "“ short lengths of ribonucleic acid that appear to regulate protein production "“ go up or down in the songbird brain...

U.S. biologists say they've discovered unusual gene activity in the brains of zebra finches occurs after the birds hear a new song from another bird. University of Illinois Professor David Clayton and his colleagues said they determined when a zebra finch hears a new song from a member of its own species, the experience affects thousand of genes, offering a new picture of memory in the songbird brain. Clayton said the finding was a surprise since he hadn't expected to see so many genes...

 When a zebra finch hears a new song from a member of its own species, the experience changes gene expression in its brain in unexpected ways, researchers report. The sequential switching on and off of thousands of genes after a bird hears a new tune offers a new picture of memory in the songbird brain.The finding, detailed this month in the Proceedings of the National Academy of Sciences, was a surprise, said principal investigator David Clayton, a professor of cell and developmental...
