CHILDHOOD: A WINDOW OF

OPPORTUNITY

431/661

The human brain is by no means fully formed at birth. It

continues to shape itself through life, with the most intense

growth occurring during childhood. Children are

born with many more neurons than their mature brain

will retain; through a process known as "pruning" the

brain actually loses the neuronal connections that are

less used, and forms strong connections in those synaptic

circuits that have been utilized the most. Pruning,

by doing away with extraneous synapses, improves the

signal-to-noise ratio in the brain by removing the cause

of the "noise." This process is constant and quick; synaptic

connections can form in a matter of hours or days.

Experience, particularly in childhood, sculpts the brain.

The classic demonstration of the impact of experience

on brain growth was by Nobel Prize-winners Thorsten

Wiesel and David Hubel, both neuroscientists. 10 They

showed that in cats and monkeys, there was a critical

period during the first few months of life for the development

of the synapses that carry signals from the eye

to the visual cortex, where those signals are interpreted.

If one eye was kept closed during that period, the number

of synapses from that eye to the visual cortex

dwindled away, while those from the open eye multiplied.

If after the critical period ended the closed eye
