Topic: vestibular signals

Understanding how the brain encodes movements is vital for motor control. Research suggests that this involves comparing proprioceptive inputs from the body with an internal model of expected movement. When these signals match, vestibular signals---which would otherwise stabilize the head against movements---are suppressed, allowing voluntary movement to occur. This mechanism implies that integrating proprioceptive and vestibular inputs is crucial for effective coordination. While previous studies indicate the involvement of multiple brain areas, with the PIVC at the forefront, the mechanisms

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
