Megamap: flexible representation of a large space embedded with nonspatial information by a hippocampal attractor network.

abstract：:Remembered object locations are stored in an eye-fixed reference frame, so that every time the eyes move, spatial representations must be updated for the arm-motor system to reflect the target's new relative position. To date, studies have not investigated how the brain updates these spatial representations during oth...
