Right-  Hubel & Weisel. They got the Nobel for this (along with Roger
Sperry). They showed that the tytpes of pattern-responding cells that
developed in visual cortex was dependant on early experience.

What we can learn form this: Don't rely on Time and Newsweek to deliver
scientific reporting. ;-) The more stimulation you can provide to a child,
the better, and the earlier you provide it, the better. One of the
strongest early-childhood correlates to later academic success is whether
the child was read to. Surprise.
