| Research Abstract |
Songbird basal ganglia nucleus Area X is essential for vocal learning in the critical period. This study reveals that singing-related Area X neurons frequently show phasic increase of spiking activity while birds are naturally sleeping. This replay-like spontaneous activity of Area X neurons during sleep may be important for vocal learning in the critical period. Moreover, the method for disturbing Area X activity while recording neural activity in freely behaving songbird has been established.
