The brain requires change/pattern for anything to reach consciousness. A "frozen" image is still oscillating light on your photoreceptors. Your brain is always incorporating some kind of memory or recent change with every experience you have...sound isn't special.
- whatshisface 7y agoThe oscillations of the light you see is on the tetrahertz scale, and goes nowhere close to being perceived as changing by your brain. Your rods and cones don't directly measure the electric or magnetic field vectors, they interact chemically with individual photons.
- TaupeRanger 7y agoYou completely missed the point. The oscillation of incoming photons is what allows the photoreceptors to send distinguishable patterns to the brain. You can say that the oscillation "starts" in the light waves or in the chemical reactions. It doesn't matter - the point was that vision requires change just like audition.
