Actually, the periphery is more
sensitive to motion.
The rods are much-fater than
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 shape of the body :-]
[For those who have it, the necessary
"vector" stuff is given in AoK, Ap6.]
