Learning is a dynamic process, that begins in early childhood. It occurs in 3 domains of development (sensory & motor, social & emotional and cognitive and language). It forms a critical foundation for acquisition of later life skills. Environment, genetics, microbiome and learning influence myelination whereby nutrition is one such modifiable factor that readily influences myelination. There are also specific regions of the brain which are involved in orchestrating sociability. Recent studies have demonstrated that these regions show a steep increase in myelination during toddlerhood. Nutrition may influence sociability as well as underlying brain development, such as myelination in the social brain.
