Temperature induced syllable breaking unveils nonlinearly interacting timescales in birdsong motor pathway
The nature of telencephalic control over premotor and motor circuits is debated. Hypotheses range from complete usurping of downstream circuitry to highly interactive mechanisms of control. We show theoretically and experimentally, that telencephalic song motor control in canaries is consistent with...
