     Epigenetics deals with the regulation of genetic activity within a cell - which genes are switched on or off, and when it happens.

     The nuts and bolts of how this happens revolves around the massively trendy field of “epigenetics,” revealing how early life experience causes long-lasting changes in gene expression in particular brain regions.
