Yixuan Ku obtained his B.S. and Ph.D. from Tsinghua University, and finished his post-doctoral training at University of California, San Francisco (UCSF). He joined East China Normal University as an Associate Professor in 2012, and he is now a full Professor at the School of Psychology and Cognitive Science, and served as a PI of MAC (memory, attention and cognition) Lab.

Prof. Ku focused on neural mechanisms underlying human memory and attention. He used multimodal neuroimaging methods and computational models to understand the cognitive processes, and tried to apply these mechanisms in the special groups of people (ageing adults, schizophrenia patients, children with autism spectrum disorder). His research got published in Brain Stimulation, Cerebral Cortex, European Journal of Neuroscience, Journal of Neurophysiology, Neurobiology of Aging, Neuropsychologia, et al. He served as a PI or co-PI in multiple grants, including the National Natural Science Foundation of China, and the National Key Fundamental Research (973) Program.

Research Interests

  • Interaction between attention and working memory

Working memory is a fundamental cognitive function. However, its capacity is severely limited. Therefore, enhancing target representation as well as inhibiting distraction during working memory is critical. Prof. Ku uses EEG and fMRI to investigate (i) how selective attention influence the representation in working memory; (ii) age-related decline for these processes; (iii) using transcranial magnetic stimulation (TMS) and transcranial current stimulation (tCS) to enhance these processes.

  • Neural mechanisms underlying the precision of working memory

Not only the number of items stored in working memory is limited, the precision of the representations in working memory is decreasing with greater load. Dr. Ku is interested in the neural mechanisms underlying these capacity and precision limits, and these processes in psychiatric (schizophrenia) and developmental (autism) disorders.
