Sensory perception emerges from the integration of multisensory inputs, a process previously attributed to higher-order cortices. However, increasing evidence suggests that the primary visual cortex (V1) also processes non-visual stimuli. Here, we investigated the response of V1 to visual, auditory, and somatosensory stimuli in awake, head-fixed mice using evoked local field potentials (eLFP), multi- and single-unit recordings. Our results demonstrate that V1 responds to auditory and somatosensory inputs with distinct frequency band modulations and firing rate patterns across monocular and binocular regions. Notably, somatosensory stimuli elicited the fastest response latencies, suggesting a privileged role in murine sensory processing. Auditory and somatosensory stimuli modulated V1 activity similarly to contralateral visual inputs, whereas ipsilateral visual stimulation resulted in weaker responses. These findings indicate that V1 is not solely dedicated to vision but also responds to auditory and somatosensory stimuli, supporting a potential role in multisensory processing.
