PhD student Sorbonne University. Research interests: Research interests: Older adults exhibit prominent impairments in their capacity to reorient and navigate in unfamiliar environments. In the literature, the impact of visuo-cognitive ageing on spatial navigation abilities remains elusive. She is particularly interested in understanding how modulations of the visual environment affect underlying patterns of brain activity and ultimately spatial navigation across the lifespan. Using structural and functional magnetic resonance imaging (fMRI), She will concentrate on three levels of neural integration: scene-selective regions (at the crossroads between visual and spatial information processing), grid cell-like representations in the entorhinal cortex and hippocampal subfields. This project might provide insights to distinguish the behavioural and cortical changes linked to normal ageing from those related to pathogenic processes characterised by deficits in spatial navigation, such as Alzheimer’s disease.
