Temporal Processing in Retina?

[Claudius Schnoerr]

Hello, 

I know, that the retina reduces the spatial information (decorrelation).
Are there also some experimental facts about temporal processing 
and information reduction in the retina?

Have the neurons (perhaps the motion-sensitive amacrine cells) some 
kind of memory? Or is there some recursive processing in the layers of the
retina? Or play transmission times through nerve fibers a role?
(The literature I read so far about the retina gave no answers)

Has someone measured the answer to a step-function or the temporal
filter function par example, if possible?

(If the retina make no temporal processing, where could this processing 
take place?)



I would be thankful for all hints and literature references.
