Project C1

PIs: Kathrin Finke and Christian Sorg

Visual functions are known to be particularly prone to normal aging processes and also to beginning Alzheimer-type neurodegeneration. In healthy observers, certain components of visuo-attentional functioning, including perceptual processing speed and top-down control, are influenced by preparation and expectancy effects. The aim of the proposed project is to examine how normal and pathological aging modulate such active perception effects on processing speed and top-down control of attention. Furthermore, we plan to assess how resting state brain network connectivity changes mediate these age effects.
