行為研究表明，睡眠在學(xué)習(xí)中起一定作用,。與此同時(shí),，鳥鳴也被確定為對(duì)學(xué)習(xí)進(jìn)行研究的一個(gè)模型系統(tǒng)。
有人曾提出,，睡眠的成年斑胸草雀的前腦前運(yùn)動(dòng)神經(jīng)元活動(dòng)能夠反映白天的鳴叫片段,。

Behavioural studies widely implicate sleep in memory consolidation in the learning of a broad range of behaviours1, 2, 3, 4. During sleep, brain regions are reactivated5, 6, and specific patterns of neural activity are replayed7, 8, 9, 10, consistent with patterns observed in previous waking behaviour. Birdsong learning is a paradigmatic model system for skill learning11, 12, 13, 14. Song development in juvenile zebra finches (Taeniopygia guttata) is characterized by sleep-dependent circadian fluctuations in singing behaviour, with immediate post-sleep deterioration in song structure followed by recovery later in the day15. In sleeping adult birds, spontaneous bursting activity of forebrain premotor neurons in the robust nucleus of the arcopallium (RA) carries information about daytime singing16. Here we show that, in juvenile zebra finches, playback during the day of an adult 'tutor' song induced profound and tutor-song-specific changes in bursting activity of RA neurons during the following night of sleep. The night-time neuronal changes preceded tutor-song-induced changes in singing, first observed the following day. Interruption of auditory feedback greatly reduced sleep bursting and prevented the tutor-song-specific neuronal remodelling. Thus, night-time neuronal activity is shaped by the interaction of the song model (sensory template) and auditory feedback, with changes in night-time activity preceding the onset of practice associated with vocal learning. We hypothesize that night-time bursting induces adaptive changes in premotor networks during sleep as part of vocal learning. By this hypothesis, adaptive changes driven by replay of sensory information at night and by evaluation of sensory feedback during the day interact to produce the complex circadian patterns seen early in vocal development.
