| Hi,
|
| I think you are wrong.
|
| "Handbook of Perception and Human Performance" page 16-8:
|
| "It is sometimes mistakenly claimed that the peripheral retina is more
| sensitive to motion than the fovea. In fact the threshold of motion
| increases steadily with eccentricity"
|
| Although the rods are more sensitive to motion than cones, there are
| many other factors that can influence the motion sensitivity of fovea
| and other parts of field of view. For example, each receptor is
| connected to one ganglion cell in the fovea, but at the periphery 25
| receptors are connected to 1 ganglion.
|
| What is your reference?
| Sorry but I didn't understand the meaning of "AoK, Ap6".
|
| Thanks
|
