It says the medial entorhinal cortex supplies a map-like framework, built mainly from the body's own movement signals plus information about boundaries and scenes, that situates an experience in space. If the model holds, it would explain how the hippocampus anchors memories to a spatial setting, and it would replace the older view that this region simply carries 'spatial' information.","findings":["The common view that the medial entorhinal cortex carries spatial input and the lateral carries non-spatial input is said to need revision in light of new data.","The medial entorhinal cortex is proposed to support path integration within a global frame of reference, giving the hippocampus a coordinate system for spatial context.","The lateral entorhinal cortex is proposed to process individual items and locations in a local frame of reference, mainly from external sensory input, supplying the content of an experience."],"terms":[{"term":"path integration","means":"Keeping track of one's current position by adding up one's own movements from a starting point, without relying on landmarks."},{"term":"global frame of reference","means":"A spatial framework covering the whole environment, against which positions and movements can be placed."},{"term":"self-motion cues","means":"Signals generated by one's own movement, such as those from balance, muscle effort or the sense of speed and direction."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-25T15:16:31.835Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-25T15:16:31.835Z","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.
