Epigenetics can play a role in how strong we feel about something. It controls not only which genes are activated but by how much they are activated. It can create too much of a good thing in our genes and lead to mood disorders. Johns Hopkins Epigenetics Center is investigating epigenetic variations that might play a role in stress, depression, and bipolar disorder. These new studies may lead to better understanding of mood swings, depression and the effects of stress on humans.

Epigenetics is a switch that turns ON/OFF our genes but it is also a dimmer that controls how much ON/OFF is present. This makes tracking epigenetics much more difficult.
