Epigenetics
Epigenetics is the molecular and
cellular mechanisms governing the
function of normal genes [all the 100
billion neurons in your head have
the same DNA].

What is experience?
The stimuli that you encounter both
pre- and post-natally as well as in later
stages differentiate neuron function.
Examples: sound, touch, vision, smell,
food, thoughts, drugs, injury, disease,
physical activity, etc.
Experience begins in utero that effects
the differentiation and function of the
neurons in the brain.

Experience-Based Brain Development in
the early years of life sets neurological
and biological pathways throughout life
that affect:
Health(physical and mental)
Learning (literacy)
Behaviour

Early Child Development and Language
Starts early – first 7 months –
neurons differentiate language
sounds (e.g. English, Japanese)
Sets capability for mastering
multiple languages in early life
Sets literacy, language and learning
trajectory for the second and third
stages of development

Policies to Foster Human Capital
"We cannot afford to postpone investing in
children until they become adults nor can we
wait until they reach school - a time when it
may be too late to intervene."
Heckman, J., 2001
(Nobel Prize Economics, 2000)

Social Determinants of Health

Chapter 5 – Equity from the Start
Recommendation 5.1:
WHO and UN Children’s Fund
(UNICEF) set up an interagency
mechanism to ensure policy coherence
for early child development such that,
across agencies, a comprehensive
approach to early child development is
acted on.
WHO, August 2008
Recommendation 5.2
The Commission recommends that:
Governments build universal
coverage of a comprehensive
package of quality early child
development programmes and
services for children, mothers, and
other caregivers, regardless of ability
to pay.
WHO, August 2008
10-002
Of all the countries in the Americas,
Cuba’s programs of nutrition and
stimulation for rural and urban children
provide the best example of equity for
early human development in the
Americas. We all can learn from what
Cuba has accomplished.
