Advances in neuroscience have revealed that the process of brain development is driven by a dynamic interaction between the genome (nature) and the environment (nurture).25 Epigenetic mechanisms like DNA methylation and histone acetylation are able to transduce experiences with the environment into long - lasting, even intergenerational changes in gene expression.26 — 35 So although the inherited genetic program is thought to provide a general blueprint for brain architecture, the environment is able to influence which genes are used, when they are used during the course of development, and where they are used within the developing brain.
