Barnes, Deborah M. "Brain Architecture: Beyond Genes," Science 233 (11 July 1986), pp.
This is an astonishing article! Science here announces that there may be something, an
"extrogenetic factor," which influences the construction of brain circuitry. This startling
discovery comes to these biologists as a result of their seeing that the human brain, with its
enormous number of synapses, cannot possibly be explained in terms of genes alone. There
simply aren't enough human genes. Therefore, there must be something out there which
influences the way the brain gets structured. Dare they even whisper the word, Environment?
There are people stumbling over truth here and they admit that there may be something -
radiation, chemistry, environment - which is influential in determining structure.
"Our ability to adapt to an everchanging environment by changing our brains may be very
positive..." Science has spoken!
The biological reductionism of this magazine is noteworthy.
