| Outline of Final Research Achievements |
Juvenile songbirds listen to a tutor song and memorize it during critical period. Thereafter, they improve their vocalizations by comparing their ongoing songs and memorized tutor song. In this study, we searched for neurons which represent tutor song memory by recording neuronal activity in freely behaving condition. We found that a group of auditory cortical neurons which exhibit selective auditory responses to the memorized tutor song. These tutor song selective auditory cortical neurons may represent tutor song memory.
