Fig. 3From: The effect of amyloid deposition on longitudinal resting-state functional connectivity in cognitively normal older adultsAn interactive effect of amyloid deposition (PiB) was found in the relationship between left middle frontal gyrus connectivity in the memory encoding network and cognitive function (attention/processing speed, left; executive function, right). While our analyses used continuous amyloid as measured by PiB, we used the definitions of Aß negative and positive as groupingsBack to article page
