Study Indicates That Brain Wiring Is Largely Inborn
"DURHAM, N.C. _ Neurobiologists at Duke university Medical Center mapping
the developing visual systems of newborn ferrets have discovered evidence
challenging the long-held view that the brain's circuitry is largely wired
by experience. Rather, they contend, much of the circuitry is inborn, with
experience acting merely to preserve and enhance existing connections...."

| What is a molecular label? The article refers to molecular labels, and I
couldn't quickly find out what they were on the 'net.

In this context, I believe it means specific proteins or other compounds
embedded in cell membranes, acting as signals to growing neurons, to make
connections more likely in one direction and less likely in others.

Even if this turned out to be true, there's nothing "merely" about
preserving and enhancing existing connections.

Perhaps the original Duke university press release does not use the word
"merely."
I don't know if this article misrepresents the conclusions of the research
team, which was published in the November issue of Science magazine, but
regardless, it seems well worth reading.
