10-008 Human Development Nature Nurture Genes Epigenetics Stimulation and Nutrition Gene Function Neurobiological Pathways Physical Mental Learning Health Health
10-004 need new number 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].
08-026 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. Kolb, U Lethbridge
Experience-Based Brain Development in the early years of life sets neurological and biological pathways throughout life that affect: 03-080 Health(physical and mental) Learning (literacy) Behaviour
Early Human Development and Literacy & Health
04-200 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

07-001 Early Experience and Brain Architecture and Function Affects gene expression and neural pathways Shapes emotion, regulates temperament and social development Shapes perceptual and cognitive ability Shapes physical and mental health and behaviour in adult life Shapes physical activity (e.g. skiing, swimming, etc.) Shapes language and literacy capability

02-056 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)
08-151 WHO – Marmot Commission on 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.
