Sensorimotor Neuroscience and Ageing
Our research is geared toward revealing the dynamical and neural principles underlying sensorimotor integration and specifically applying this understanding to deficits in the motor system associated with the ageing process. This work involves the use of transcranial magnetic stimulation (TMS) to measure age-related changes in brain plasticity mechanisms and electroencephalography (EEG) to assess changes in connectivity patterns between brain regions. The ultimate aim of the research is to evaluate the use of non-invasive brain stimulation protocols and plasticity-based training programs to maintain coordinated motor behaviour into later life and to minimise, delay or even prevent symptoms of brain disease, such as Alzheimer's disease.
The ability to harness neuroplasticity for clinical applications has far reaching implications for the maintenance of motor and cognitive function in older adults. Understanding the factors that contribute to individual differences in brain plasticity will offer unique and novel targets to promote individual brain health and well-being across the lifespan. Ultimately, modulating brain plasticity may minimise, delay or even prevent symptoms of brain disease, such as Alzheimer's disease, and to help maintain coordinated motor behaviour into later life. Measures of brain plasticity as employed in the proposed research may provide critical predictors and early biomarkers of disease. Empirically measuring plasticity may thus serve plasticity-based training programs aimed at promoting brain health and cognitive and motor function across the life span.
