The Great Brain Debate: Nature or Nurture?

Dowling presents a complex subject in a very readable manner...the way our brain is influenced by our heredity and our environment. It is fascinating to read about the way our brain develops and adapts from infancy to old age. Really makes you realise that the brain is still malleable as we grow older, gives me the assurance that I will still be capable of acquiring new skills and knowledge after 60. Chemistry is not always the main cause of temperament, mental, psychological or relationship issues...so seeking relief with a psychiatrist's prescription (or using recreational drugs) may not always be the most optimum solution. Reminds me of Carl Sagan's clarity in "Billions and Billions" and "Science a Candle in the Dark". A great book for the well-informed amateur and for the amateur who seeks to be well-informed.

This book reviews the state-of-the-art in brain development and on the factors driving its state. The author's viewpoint is the one of a neurocientist, hence more centered on neuronal molding than on learning. The author shows that what we call brain development is actually about partially limiting the adaptivity of the brain circuitry. Still, there is always potential for adaptation, age does not prevent the molding of the brain. The evolution of the brain is driven both by genetics and learning. So how we use it matters a lot! Saying that one is too old to change is just an excuse.
