北京师范大学认知神经科学与学习国家重点实验室郭桃梅课题组2022年2月在《Cerebral Cortex》发表论文《The cerebellum and cognition: further evidence for its role in language control》。该研究首次综合运用功能磁共振成像(fMRI)和经颅直流电刺激(tDCS)试图以双语者语言加工为突破口揭示小脑与高级认知功能的关系。
近年来,郭桃梅课题组开展的一系列研究 (Yuan et al., 2021a, 2021b, Zhang et al., 2021, Wu et al., 2021, Chen et al., 2020, Wu et al., 2020, 2019) 综合运用fMRI技术和事件相关电位技术揭示了双语者语言产生过程中语言控制的脑网络及其可塑性。该研究在本课题组已有研究的基础上,综合运用fMRI和tDCS技术在国际双语研究领域详细揭示了小脑的重要作用,也提出了未来研究探索小脑参与高级认知功能的分析框架。未来研究可以从小脑的(偏侧化)激活模式、大脑-小脑网络及其和行为之间的关系、训练/神经调控/脑损伤带来的神经可塑性变化的角度进一步探索小脑在其他认知功能中的作用。
