SPATIAL REPRESENTATION, SPATIAL NAVIGATION AND THE HIPPOCAMPUS

This paper presents a cognitive neuroscience perspective on how the br ain might represent position of the body in space, and how the brain m ight represent motion through space (navigation), with particular refe rence to the mammalian hippocampus. Data which show the hippocampus ca n represent both the position of the body in space and the movement of the body through space are presented and discussed. The hippocampal r epresentation of position and navigation seems to be in allocentric (w orld-centered) coordinates. Some hypotheses on how the brain processes spatial information are presented and discussed.
