Spatial navigation relies on external cues, such as visual objects, to anchor internal representations of space. In rodents, moving a visual landmark results in a corresponding shift in the tuning of head direction (HD) cells1. However, little is known about where visual objects are encoded in the mouse brain2 or how visual objects modulate the firing properties of HD cells3. Using functional ultrasound (fUS) imaging4, we conducted a brain-wide screen to identify areas preferentially activated by visual objects compared to scrambled versions of the same stimuli. Our results showed that while v
