| Outline of Final Research Achievements |
Vocal control requires the interplay between the cortical and subcortical regions, however, their dynamical interaction during vocalization was remain elusive. Songbirds learn and sing highly complex vocal patterns and their cortical and subcortical song nuclei necessary for learning and singing were well identified. Therefore, they serve as a suitable model animal to study the interaction between cortical-subcortical regions during vocalization of learned sounds. Previous hypothesis postulated that cortical regions contain a chain like structure to generate precise timing to control the precise vocal gestures. However, we have shown that, by using peltier brain cooling, computer simulations, and intracellular recordings in singing birds, songs are the product of the cortical and subcortical chain structure instead of localized chain in the cortex.
