Episode notes

When you look at mating behavior of various animals, you see an aggressive component sometimes, but not always. Is it species specific? Is it context specific? And more generally, do you think that there is cross talk between these different neuronal populations and the animal itself might be kind of confused about what's going on? Right. Great, great questions. I don't want to answer problem or five, but I'll just ask the question. So the other day I was watching ferrets mate, right, and they're mustalids and they're mating behavior. It seems to me that there is some crossover of aggression and mating behavior circuitry during the act of mating. We have no idea.

My guest is David Anderson, PhD, a world expert in the science of sexual behavior, violent aggression, fear and other motivated states. Dr. Anderson is a Professor of Biology at the California Institute of Technology (Caltech), a member of the National Academy of Sciences and an investigator with the Howard Hughes Medical Institute (HHMI). We discuss how states of mind (and body) arise and persist and how they probably better explain human behavior than emotions per se. We also discuss the many kinds of arousal that create varying levels of pressure for certain behaviors to emerge. We discuss different types of violent aggression and how they are impacted by biological sex, gender, context, prior experience, and hormones, and the neural interconnectedness of fear, aggression and sexual behavior. We also discuss peptides and their role in social isolation-induced anxiety and aggression. Dr. Anderson also describes novel, potentially powerful therapeutics for mental health. This episode should interest anyone wanting to learn more about mental health, human emotions, sexual and/or violent behavior.
