Navigation: the mammalian model (discussion)

Summary form only given. The influence of inertial and other categories of motion-induced spatial information is being widely acknowledged in the interpretation of single cell recordings and in the conception of neural navigation models. This is mainly due to the repeated observation that place cells retain their firing fields and head direction cells their preferred compass direction independently of changes in familiar visual references, and even in complete darkness. Pushing the importance of path integration to its extreme consequences, the hippocampus has been conceived as a path integration system, in which external landmarks are secondarily bound to a hard-wired network that allows self-localisation to occur through motion cues
