We published a research article "Intracranial EEG reveals working memory-related dynamics and connectivity in human white matter" in Science Bulletin. Using human intracranial EEG recordings, this study provides electrophysiological evidence that human white matter exhibits tract- and frequency-specific power changes as working memory load increases. The study further shows that within-frequency functional connectivity remains largely stable, whereas cross-frequency connectivity is selectively strengthened with increasing load. These results provide a physiological framework for understanding white matter signals in relation to working memory and offer new insight into how white matter pathology may disrupt cognition across brain disorders.

This study was accomplished with our collaborators, Prof. Guoguang Zhao and Prof. Yongzhi Shan, from Xuanwu Hospital Capital Medical University. Congratulations to Shen Zhang and Longzhou Xu. Thanks to all the collaborators who contributed to the work, especially Haoshu Xu, Lirou Tan and Zhilin Li.
