- claim_text
In mouse posterior parietal cortex, allocentric head-direction tuning becomes stronger and egocentric boundary tuning weaker when gravity and visual cues are made to disagree, and individual head-direction cells can switch between gravity-anchored and visually anchored reference frames — indicating PPC implements a flexible, demand-dependent reference-frame selection rather than a fixed allocentric attractor.
