Are all spatial reference frames egocentric? Reinterpreting evidence for allocentric,object-centered,or world-centered reference frames

The use and neural representation of egocentric spatial reference frames is well-documented. in contrast,whether the brain represents spatial relationships between objects in allocentric,object-centered,or world-centered coordinates is debated. here,i review behavioral,neuropsychological,neurophysiological (neuronal recording),and neuroimaging evidence for and against allocentric,object-centered,or world-centered spatial reference frames. based on theoretical considerations,simulations,and empirical findings from spatial navigation,spatial judgments,and goal-directed movements,i suggest that all spatial representations may in fact be dependent on egocentric reference frames. © 2015 filimon.
