人类和鸣禽在发声学习方面有着共同的关键特征，分别表现在说话和唱歌上。这些行为之间惊人的相似之处包括，两者都是在大脑声音学习能力达到顶峰的发育关键期获得的。这两种行为在其潜在的大脑区域的整体结构中表现出相似性，其特征在于皮质-纹状体-丘脑回路和从皮质神经元到控制发声器官的脑干运动神经元的直接投射。这些神经类比延伸到分子水平，某些歌曲控制区域与人类大脑中的语音相关区域共享收敛的转录谱。这种进化上的趋同为我们提供了一个前所未有的机会，让我们能够破译发声学习的共同神经遗传基础。鸣禽模型的一个关键优势是，它允许描绘大脑中由学习的发声行为驱动的活动依赖性转录变化。为了利用这一优势，我们使用了我们实验室先前发表的数据集，这些数据集将基因共表达网络与关键期关闭内和关闭后的学习发声特征相关联，以探索与语言有关的基因的功能相关性。我们通过汇集证据来询问特定的基因和细胞过程：人类特有的进化变化，智力相关的表型和鸣禽发声学习基因共表达的相关性。这篇文章是主题问题“动物交流能教我们什么关于人类语言？”的一部分。
Humans and songbirds share the key trait of vocal learning, manifested in speech and song, respectively. Striking analogies between these behaviours include that both are acquired during developmental critical periods when the brain's ability for vocal learning peaks. Both behaviours show similarities in the overall architecture of their underlying brain areas, characterized by cortico-striato-thalamic loops and direct projections from cortical neurons onto brainstem motor neurons that control the vocal organs. These neural analogies extend to the molecular level, with certain song control regions sharing convergent transcriptional profiles with speech-related regions in the human brain. This evolutionary convergence offers an unprecedented opportunity to decipher the shared neurogenetic underpinnings of vocal learning. A key strength of the songbird model is that it allows for the delineation of activity-dependent transcriptional changes in the brain that are driven by learned vocal behaviour. To capitalize on this advantage, we used previously published datasets from our laboratory that correlate gene co-expression networks to features of learned vocalization within and after critical period closure to probe the functional relevance of genes implicated in language. We interrogate specific genes and cellular processes through converging lines of evidence: human-specific evolutionary changes, intelligence-related phenotypes and relevance to vocal learning gene co-expression in songbirds.This article is part of the theme issue ‘What can animal communication teach us about human language?’
