The brain's energy consumption reaches full adult levels at around two years of age. By three the little child's brain is actually twice as active as an adult brain. ... It begins to decline around [nine or ten] but reaches adult levels only at about eighteen.
At birth, each neuron in the cerebral cortex has around 2,500 synapses. The number of synapses reaches its peak at two o three years of age, when there are about 15,000 synapses per neuron. This is actually many more that in an adult brain. -- The Scientist in the Crib. p. 186.

Does this neuron connectedness with elevated levels of activity lie at the source of child creativity?
