Two brain regions interact to help finches know when and how to tailor their songs for specific situations

Researchers at UC San Francisco have shown how the Bengalese finch, a domesticated songbird, can learn to tweak its song in specific ways depending on context, which could shed light on how the human brain learns to apply different rules depending on the situation, and have implications for understanding human language and movement disorders.
The study, published November 16, 2017, in Neuron, showed that finches switch from generic to specific versions of their songs depending on the situation they are in. What's more, the researchers identified two distinct areas in the birds' brains dedicated to this learning process: one region that encodes generalizable rules to produce default songs, and another area that can override the default pathway to produce different sounds for different contexts.
