Science, Creation & EvolutionEvolution vs. Intelligent Design for DummiesNo, it can't detect motion. But what it can do, is lead your nervous system to confabulate motion where there is none. The sudden disappearance of an object (tracked by moving one's head) into the secondary blind spot, causes the optic tectum to confabulate movement, in much the same way that the primary blind spot causes the optic tectum to confabulate a background that you aren't really seeing. It samples the information around the blind spot, and tries to match that in the data it makes up. |
