Multiple sources innervate the visual thalamus to influence image-forming vision prior cortex, yet it remains unclear how non-retinal and retinal input coordinate shape thalamic selectivity. Using dual-color two-photon calcium imaging in of awake mice, we observed similar coarse-scale retinotopic organization between axons superior colliculus neurons ganglion cells, both providing strong converging excitatory neurons. At a fine scale ∼10 µm, collicular boutons often shared feature preferences with nearby boutons. Inhibiting significantly suppressed responses specifically reduced motion selectivity preferring nasal-to-temporal motion. The reduction could be result silencing sharply tuned direction-selective colliculogeniculate input. These findings suggest that is not merely relay but selectively integrates inputs from multiple regions build stimulus information transmitted cortex.
