The Biology of Aggression, Mating, & Arousal | Dr. David Anderson

About this video

Dr. David Anderson, a professor of biology at Caltech, joins Huberman to discuss the biology of aggression, mating and arousal, drawing on his book The Nature of the Beast. Dr. Anderson argues emotions such as happiness, sadness and anger are subcategories of underlying nervous-system states that bias action or inaction and shape how we interpret our surroundings. The conversation covers why aggression can become rage, the boundaries and overlap between aggression and sexual behaviour, and differences among male-male, male-female and female-female aggression. In the middle excerpt Dr. Anderson explains a counterintuitive finding from animal work: many effects of testosterone on aggression are mediated by its conversion, through aromatization, into estrogen, and aggression neurons also express the progesterone receptor, while female mouse aggression, he describes, rises sharply only while mothers are nursing pups.

Key takeaways

• Dr. Anderson describes aggression neurons expressing the progesterone receptor in animal studies.
• Dr. Anderson explains female mouse aggression is concentrated in the period of nursing pups.
• Huberman presents Dr. Anderson’s book as grounded in research and contrary to common myths about emotions.
