在发育早期的感觉体验塑造了更高的认知功能，如人类的语言习得和鸟类的歌唱学习。斑马雀在发育的敏感期先后接触了两首不同的歌曲“导师”，能够从第二位导师那里学习，并最终模仿他的歌曲的各个方面，但学习第二首歌所涉及的神经基础尚不清楚。我们使用功能磁共振成像来检查与顺序学习两首歌曲相关的神经活动。我们发现，第二首歌的习得改变了听觉中脑的偏侧化。有趣的是，尾侧核(NCL)的活动与第二声模仿的保真度有关，NCL是毗邻次级听觉皮质的区域。这些发现表明，与另一位导师一起的经历可以永久性地改变涉及听觉和歌曲学习的大脑区域的神经活动。在发育的不同阶段，从两位“导师”那里学习歌曲会永久性地改变斑雀听觉处理和学习区域的神经活动。
Sensory experiences in early development shape higher cognitive functions such as language acquisition in humans and song learning in birds. Zebra finches (Taeniopygia guttata) sequentially exposed to two different song ‘tutors’ during the sensitive period in development are able to learn from their second tutor and eventually imitate aspects of his song, but the neural substrate involved in learning a second song is unknown. We used fMRI to examine neural activity associated with learning two songs sequentially. We found that acquisition of a second song changes lateralization of the auditory midbrain. Interestingly, activity in the caudolateral Nidopallium (NCL), a region adjacent to the secondary auditory cortex, was related to the fidelity of second-song imitation. These findings demonstrate that experience with a second tutor can permanently alter neural activity in brain regions involved in auditory perception and song learning. Learning song from two ‘tutors’ at different points in development permanently alters neural activity in auditory processing and learning regions in zebra finches.
