Mooney Images

A timeline for song learning: a juvenile male zebra finch (foreground) listens to and memorizes the song of an adult male tutor (background), then uses auditory feedback to match its song to the memorized model.


Two photon images of a dentrite of a song promoter neuron taken at 2h intervals reveals the addition and loss of dentritic spines (+, -)  


Song motor (black) and anterior forebrain (red) pathways in the songbird's brain are essential to singing and song learning.


Ascending auditory pathways shown into the relationship to the song system.


Intracellular current clamp recording from a song premoter neuron in a singing bird shows the remarkably stereotyped pattern of synaptic activity (black and red regions) as the bird repeats its song motif (sonogram at top).
