The Effects of a Lutein + Zeaxanthin Intervention on Cognitive Function and Neural Efficiency
Past research suggests that retinal lutein levels are related to cognitive function as
measured via behavioral tests. The goal of the present study is to investigate the
relationship between lutein and cognitive function in a wider variety of the population
(young, healthy adults and older adults), using a wider variety of methods (behavioral
testing and neuroimaging).
