Head-direction (HD) cells function as the brain's neuronal compass. Their activity is based on vestibular signals and controlled by visual landmarks. The integration of multisensory signals during passive rotation and the role of the presubiculum in merging vestibular and visual inputs are yet to be fully understood.We manipulated vestibular and visual cues using a novel paradigm. Head-fixed mice were rotated on a motorized platform in a pseudo-random fashion, covering all angles, while surrounded by a semi-transparent dome displaying visual cues. Using Neuropixel probes, we investigated the a
