Bi-stable perception (experiment)
When you experience bi-stable perception, the image is not changing but your perception is. How does it happen? “Bi-stable perception” is the result of selecting neural signals among the neurons that are competing each other at each location that support one of the two percepts. In this phenomenon, input signals from an image are constantly re-organized such that two different percepts alternatively emerge from the given image. The global reversal of the percept cannot be explained if signals are processed independently at individual locations. The local signals must be organized coherently so that one of the percepts emerges at a time. This perceptual re-organization in bi-stable perception must indicate how signals are processed, are organized, and reach to consciousness. This is why bi-stable perception has been the key tool to investigate the emergence of perceptual organization.
