Slide 3		Genes are the building blocks Environment is multiple factors that turn genes on or off, causing cells to differentiate, divide, sprout new connection Environments may be the number of neurons, firing rate, hormonal factors, stress hormones that even go through the breast milk, trauma to nerve cells, events and experiences perceived by the brain. Couls also be obstetrical complications, intrauterine infections, nutrition, stressful life events

The decreased ability to feel pleasure related to low dopamine in this area drives the person to seek external gratification through actions, or substances
