Vincent Van Gogh - Sorrowing Old Man (At Eternity's Gate) 1890

We go into significantly more detail regarding some of what we know about how circuits in the brain encode anxiety and fear. This involves a discussion of how brain structures really interact with one another. We also delve into the relationships between genetics, epigenetics, and emotion.
