Research Interests

Dr. Leung is interested in the scientific basis of cognitive rehabilitation. The long-term goal of her research is to understand the neural mechanisms underlying cognitive recovery and investigate treatment strategies for improving cognitive functions such as memory, attention and executive function, as well as occupational performance for occupational therapy practice. She uses multiple research methods including behavioral and neuropsychological tests, functional magnetic resonance imaging, and event-related potential. Her research participants include healthy adults and special population such as people with stroke, traumatic brain injury, and fetal alcohol spectrum disorder.


Research

Current Research Areas

  • Neural basis of executive function and working memory
  • Working memory training for improving functional abilities
  • Brain-behavior characteristics in adults with fetal alcohol spectrum disorders

Scholarly Activities

Research - Neural basis of auditory working memory

Working memory allow us to manipulate both new and old memories over a short period of time. There are many examples of auditory working memory in our daily life, e.g., keeping track of auditory signals in a train station, or recalling sound tracks to enjoy music. Dr. Leung is working to investigate the functional organization of the parietal lobe for auditory working memory, i.e., which parts of the parietal lobe are specifically activated in response to different types of sound stimuli in an auditory working memory task. This basic science research recruits healthy young adults and uses fMRI.


Research - Working memory training for improving functional abilities

Working memory training induces neural plastic changes in the brain which can facilitate cognitive and functional recovery. Dr. Leung’s work is to: (1) determine the types of cognitive and functional abilities that can be improved with working memory training; (2) investigate the patterns of neural activation after working memory training; and (3) develop a training protocol which incorporates both working memory training and task-specific training for improving occupational performance. This research recruits healthy and clinical populations, and uses neuropsychological tests and fMRI.
