I would too, but the paper magazine hit the recycle bin a few months
ago, and I can't recall which (of several) it might have been. I'm not
subscribed; I just grab from the magazine rack when I'm short of reading
material and something on the cover catches my eye.

I tried Googling yesterday, when Linda asked me the same question, but
had no luck. The content might be hidden behind a login-only site.

My recollection is that the authors deconstructed, by experimental means
(possibly using animals and damaged humans, but don't quote me) what the
optic nerve delivers when certain standardized (for their purposes)
images are viewed. 

They came up with a realization that the eye does more pre-processing -
it's not just a passive converter of photons-to-nerve-impulses - than
previously believed, and that separate component systems deliver
separate "sub-images" that are then recombined in the main body of the
visual cortex.  Among other effects, this resulted in increased
bandwidth in the vision process.... hope I'm not conflating with other
articles, now.

Drat.
