Visual input to the brain is highly dynamic during natural behavior due to movements of the eyes, head, and body through complex environments. Previous studies have shown that neurons in mouse primary visual cortex (V1) respond to eye and head movements, but how these signals are integrated with visual processing during free movement is unknown since visual physiology is generally performed under conditions of head-fixation. To address this, we performed the first measurements of visual receptive fields (RFs) from freely moving animals by using single-unit electrophysiology in V1 while simulta
