Refined techniques in brain activity analysis in zebra finches yields interesting results about how vocalization works. The research showed that by silencing of neurons in the arcopallium, a region in the brain known to be responsible for song generation, that zebra finch songs would become erratic and incomplete. It also demonstrated how precise this neuronal suppression method can be in determining the function of very small groups of neurons.
