Beauty and Brains Tease

No, I’m not the first to discovery this extraordinary brain trick. I did want to share this, though, as an example of how our brain processes and stores images. Give it a try – amazing!

Sony India Interesting Ad : stare at the colored dots on this girl’s nose for 30 seconds, then quickly look at a white wall or ceiling (or anything pure white) and start blinking rapidly. Congratulations, you just processed a negative with your brain!

I invite any neuroscientists to explain the mechanism!

    not a neuroscientist, but this is a common optical illusion. i believe it has to do with the rods and cones in the eye becoming fatigued, rather than any brain function.

    How does this relate to persistence of vision?

    Thank you for your comment. I am interested in the link between the rod/cone cells in the eye and processing and storage of the image. Can anyone elaborate?

    Negaive afterimages are generated by the retina, independent of central processing.

    It’s pretty cool. Could see her positive image on the ceiling instantly. I think it’s interesting.

    Hahaha, I did this and then stared at the wall across from me, the image was huge and in focus. Also, you dont have to stare at the dots, stare at her eyes, its more natural feeling. 🙂

    (sorry, non-native speaker groping for words)

    Generally, our senses don’t report the current state of our surroundings but only change-of-state. That’s why we get used to an odor in a room, no longer notice some constant noise, or why we still can tell blue from green even if the light itself is red (be it in a club or the evening sun).

    The afterimage happens because our vision compensates for a “distortion” for a few moments after said distortion is no longer there.
