Gaining Perspective on How We See in 3-D
This video demonstrates one of the visual stimuli that Cumming uses in experiments. The moving dots give a powerful sensation of a three-dimensional cylinder, but you might see it in one of two different ways: with the front surface moving to the left or to the right. Cumming is studying which signals determine the brain state that causes you to see the cylinder move in one direction or the other.
