The meaning and functions of cross-modal sensory processing in the cortex is at center an ongoing debate. While some studies claim that such responses reflect genuine multisensory integration, others argue they are mere artifacts stimulus-evoked movement or changes internal state. We examined this issue by measuring face movements neural activity awake mouse primary auditory (A1) visual (V1) during stimulation. Visual stimuli rarely evoked movements, A1 to input remained robust even absence movement, optogenetic silencing V1 reduced responses, confirming a origin these responses. These findings directly challenge argument cross- modal purely movement-driven emphasize rather than assuming all effects artifactual, researchers must rigorously test each case. Unlike stimuli, evoke movementsFace explain sound-evoked firing VC but not visually ACSilencing suppresses ACThese results confirm (rather motor)
