| Research Abstract |
Songbird basal ganglia (BG) circuitry is critical for vocal learning, and the BG neurons shows singing-related activity. To date, it remains unknown whether the BG neurons could exhibit singing-like neural activity during sleep. This study demonstrates that (1) BG neurons in sleeping juvenile songbird exhibited characteristic neural activity similar to singing-related activity, (2) LFP recorded from adult songbird BG exhibited gamma oscillation during sleep, suggesting that these sleep-related neural activity in the songbird BG may play an important role in the learning and maintenance of song.
