Description Optic flow (the pattern of motion at the eye) controls human walking, and the disruption of visually-driven, cognitive neuronal networks involved in radial optic flow (ROF) processing contributes to spatial navigation errors in Alzheimer's disease (AD).1 These data are based on ROF motion stimuli presented in 2D, while 3D ROF stimuli (simulating real-life) have not been investigated in AD and may have different cognitive correlates. The specificity of impaired ROF perception is unknown since it has not been studied in other neurodegenerative diseases. The aim of this study was to compare the perception of 3D ROF patterns in healthy older adults (HOA), AD, and Parkinson's disease subjects with advanced motor symptoms (PD-AMS).
