Topic: free exploration

Mice sample the visual scene by moving their head and eyes. However, little is known about how eye and head position are integrated into visual processing during natural movement, because studies of visual processing are generally performed during head fixation. To address this, we analyzed the retinal input encountered during free exploration by measuring the mouse’s visual scene (“worldcam”) and eye/head position using head-mounted cameras and an inertial measurement unit (IMU). Based on these measures, we trained a neural network to estimate the retinal input by gaze-correcting the worldcam
