Natasha Rajah’s research focuses on conducting brain imaging studies in the cognitive neuroscience of aging and memory. More specifically, she uses multi-modal magnetic resonance imaging (MRI) methods to study how age-related changes in region-specific brain activity and volume, impact the function of large-scale neural networks important for episodic memory. To this aim Natasha Rajah uses multivariate statistical methods to directly examine the three-way interaction between memory performance, regional brain volumes/activity, and neural network activations in healthy young, middle-aged and older adults. The goals of her research are to understand how regional changes in brain function influence learning and memory across the adult lifespan, in both healthy and pathological aging, and how memory losses may be compensated for.
