Reading presents a real paradox to neurobiologists. It was only
invented a few thousand years ago, so there really has not been
enough time for our brain to evolve speciallzed ways to do it. How
do brain circuits produced by millions of years of evolution in a
world without written words adapt to the specific challenges of
reading? We know we have to learn the skill but how does our brain
learn to read? in the social sciences, the majority of researchers do
not see a problem. There is a widespread view that the brain is a
completely adaptable organ, capable of absorbing any form of
culture. Yet recent findings from brain imaging studies and
neurophysiology throw new light on the organization of the reading
circuits in the brain. The findings contradict this simplistic model of
a brain that merely absorbs everything from its cultural
environment. And they suggest that the architecture of our brain is
limited by strong genetic constraints though it seerns that it has still
some degree of flexibility.
