Epigenetics and the Brain: Woo-free Coolness

In my latest column for Discover, I take a look at epigenetics and the brain. Along with the genetic circuitry in the DNA of our brain cells, we also have an additional layer of molecules that can switch genes on and off. A lot of this so-called epigenome gets locked into place when our brains are first developing, but it still remains malleable throughout our lives. Our environment can rework our epigenome, and some studies suggest that this reworking may produce long-term changes in...
