Venue: The 1rd meeting room, 3rd floor, Intelligence Building 

Abstract:

With an ageing population worldwide, the incidence of cognitive decline is increasing, especially impairment in memory dependent on the function of the hippocampus. Evidence suggests that physical exercise may protect against decline in hippocampal function, however, little is known about how this improvement is mediated. My study, using MRI imaging, shows that significant cognitive improvement in aged mice following exercise results from an enhancement in strength of connections in the Dentate Gyrus (DG) network in the hippocampus. Moreover, I show this enhancement is dependent on the increased production of new neurons in the DG of the aged mice. 

Biography:

PhD Degree in Cognitive Neuroscience, Oct. 2014  Oct.2018 QBI, The University of Queensland, QLD, Australia.

Master's Degree in Cognitive Neuroscience, Sep. 2011 - Jul. 2014 School of Brain and Cognitive Sciences (State Key Lab of Cognitive Neuroscience and Learning), Beijing Normal University, Beijing, China. 

My current research is focussed on understanding the mechanisms by which exercise may prevent or even reverse cognitive decline.
