When thinking about a series on the chemistry of the brain you wouldn’t think an episode on domestic abuse would be part of the roster. For this series, sponsored by the Biochemical Society in the UK, it is. We are talking with Julianne Flanigan about how you can understand domestic abuse and PTSD, and how those two interact, from the position of a scientist looking at the chemistry of the brain. We talk about what the realities of domestic abuse are, how you research it and what science has shown when trying to understand what makes you likely to be a victim, or an abuser.
