However, it has been challenging to isolate the sensory modality that drives them and to map their cortical distribution. To address this, we develop a method that enables rotating awake, head-fixed mice under a two-photon microscope in a visual environment. Starting in layer 2\/3 of the retrosplenial cortex, a key area for vision and navigation, <strong><span style=\"color: #ff0000;\">we find that 10% of neurons report angular head velocity (AHV)<\/span><\/strong>. <strong><span style=\"color: #ff0000;\">Their tuning properties depend on vestibular input with a smaller contribution of vision at lower speeds<\/span><\/strong>. Mapping the spatial extent, <strong><span style=\"color: #ff0000;\">we find AHV cells in all cortical areas that we explored, including motor, somatosensory, visual, and posterior parietal cortex<\/span><\/strong>. Notably, <strong><span style=\"color: #ff0000;\">the vestibular and visual contributions to AHV are area dependent<\/span><\/strong>. Thus, many cortical circuits have access to AHV, enabling a diverse integration with sensorimotor and cognitive information.&#8221;<\/p>\n<p style=\"text-align: justify;\">Eivind Hennestad, Aree Witoelar, Anna R.
