Subject Alzheimer's Disease; Parkinson's Disease; Visuospatial Perception; Optic Flow; Human Walking
Description Optic flow (the pattern of motion at the eye) controls human walking. Perception of the focus of expansion (FOE) of a radially expanding pattern of moving dots (radial optic flow or ROF) is impaired in AD, but has not been investigated in PD. In the ROF illusion (ROFI), the FOE is perceived as shifted in the direction of a superimposed planar motion pattern (similar motion created by pursuit eye movements).
