双语者的大脑如何区分和控制使用哪种语言？以前的功能成像实验无法回答这个问题，因为熟练的双语者激活相同的大脑区域，而不管被测试的语言。在这里，我们发现，在左尾状核的神经元反应是敏感的语言或单词的含义的变化。通过在德英和日英双语人群中证明这种效应，我们认为左尾状核在监测和控制语言使用中起着普遍的作用。
How does the bilingual brain distinguish and control which language is in use? Previous functional imaging experiments have not been able to answer this question because proficient bilinguals activate the same brain regions irrespective of the language being tested. Here, we reveal that neuronal responses within the left caudate are sensitive to changes in the language or the meaning of words. By demonstrating this effect in populations of German-English and Japanese-English bilinguals, we suggest that the left caudate plays a universal role in monitoring and controlling the language in use.
