|| Hi friends
||
|| I am a mechanical engineer. For some
|| stupid reason I am doing research
|| on eye.
||
|| The thing that I want to know is that
|| which part of the retina is more

|| fovea is more sensitive, but I am
|| looking for a table or something that
|| compare different parts of the
|| retina.

|| Thanks you for your help

| Actually, the periphery is more
| sensitive to motion.
|
| The rods are much-fater than
| the cones.
|
| It has to be this way because
| what's going on in the fovea is
| already exposed to conscious-
| ness, but, when something hap-
| pens out in the periphery, de-
| pending on it's correlated 'vect-
| ors', it needs to not only be de-
| tected, but it has to force atten-
| tion to switch-over to it.
|
| This requires the peripheral stuff
| to be "more sensitive to motion"
| [which is not the way I'd say it].
|
| There is a =general= rule for all
| such considerations, and it applies
| rigorously across the whole nervous
| system. This general rule even determ-
| ines the [structure] of the body :-]         <--
|
| [For those who have it, the necessary
| "vector" stuff is given in AoK, Ap6.]
