title: Is song special?
abstract: Akutagawa and Konishi (2001)([this issue of Neuron]) describe the spatial and temporal pattern of SNAg (song system nuclear antigen) expression within a subset of song-associated forebrain nuclei of grass finches. The timing and estrogen inducibility of SNAg expression suggest that it may function in establishing neural connections key to vocal learning.
