and FC parameters had new stimuli (versus familiar stimuli). Conclusions: Eye movement behavior can accurately distinguish between NC, MCI and AD groups and MCI and AD have a similar oculomotor behavior, although they were still not significantly different in this study, possibly due to the cognitive heterogeneity of MCI group (which will be subdivided in the next step of this research). Interestingly, all oculomotor parameters were sensitive to new stimuli perception (versus familiar stimuli) across groups, possibly indicating a cognitive decline that may indicate a progression to AD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
