Sep 12, 2022 Dr. David Anderson, a Caltech professor and leading expert in the biology of aggression and sexual behavior, shares fascinating insights into how biological states, rather than emotions alone, drive human behavior. He discusses the neural circuits linking aggression, fear, and sexual instincts, alongside the impact of hormones and social isolation on anxiety. The talk covers innovative therapeutics for mental health, emphasizing the need for understanding the biological underpinnings of our actions and emotions.

Episode notes
State Dimensions
- States have dimensions like persistence, intensity, and generalization, differentiating them from reflexes.
- Emotions can persist after stimuli, vary in intensity, and generalize across situations, unlike simpler states like hunger.
Arousal and Valence
- Arousal and valence are distinct state dimensions, not simply linked by neurochemicals like dopamine.
- Different circuits, not just neurochemical flips, likely control the valence (positive or negative) of arousal.
Aggression Types
- Aggression is a behavior, not a state, reflecting underlying states like anger, fear, or hunger (predatory aggression).
- Optogenetics revealed specific neurons in the ventromedial hypothalamus (VMH) trigger offensive aggression, distinct from defensive or predatory aggression.
