This Past Weekend w/ Theo Von

In this wide-ranging conversation, neuroscientist Dr. David Linden delves into the intricate science behind human individuality, exploring how biology, genetics, and personal experience shape who we are. Joined by Theo, Dr. Linden discusses not only the neurological and evolutionary underpinnings of love, attraction, and identity, but also how a terminal cancer diagnosis has influenced his personal and professional outlook. The discussion bridges scientific research with deeply human themes of mortality, meaning, and connection.
Dr. Linden explains how brain injuries and depression are linked to neural pathways and neurotransmitters like serotonin, and how treatments like SSRIs compare to therapy and exercise. He explores the evolutionary basis for love and long-term bonding in humans and animals, and how genetics and biology influence attraction and sexual orientation. The conversation also touches on how science and faith can coexist, the brain’s difficulty in conceptualizing death, and the biological basis of individuality. Dr. Linden discusses the future of human evolution, the impact of biomedical advances like GLP-1 drugs, and the role of mind-body interactions in health, particularly in light of his own cancer journey.
