The claim describes how the brain's position map behaves when its internal estimate of distance travelled (path integration) conflicts with what the surroundings indicate. Small mismatches were corrected gradually and large ones by an abrupt jump, which suggests the two sources of information compete rather than simply combine. If it holds, it helps explain how a spatial map stays anchored to the world.","findings":["Early in a journey, cells fired at fixed distances from the origin, while later they fired at fixed distances from the destination.","On shortened journeys, the population vector shifted from alignment with the origin to alignment with the destination, smoothly for small mismatches and abruptly for large ones.","In a different environment the same box controlled the alignment of a different set of place cells, suggesting that the neurons do not explicitly represent objects or events."],"terms":[{"term":"path integration","means":"Keeping track of one's position by adding up self-motion, such as speed and direction, from a known starting point, without relying on landmarks."},{"term":"place cells","means":"Neurons in the hippocampus that fire when an animal is in a particular place in its environment."},{"term":"mismatch","means":"A conflict between where internal path integration says the animal is and where external cues indicate it is."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-20T10:30:29.701Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-20T10:30:29.701Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
