🗝️ Key Themes & Topics

This episode unpacks the neuroscience of fear, trauma, and PTSD, emphasizing biology, formation, and extinction tools for real-world application.

• Topic 1: Biology of Fear & Trauma – Details neural circuits like the amygdala (threat reflex hub), HPA axis (hypothalamus-pituitary-adrenals releasing adrenaline/cortisol), and autonomic arousal (sympathetic alerting vs. parasympathetic calming). Fear combines stress, anxiety, and reflexes; trauma embeds maladaptive fears via long-lasting chemicals altering gene expression.
• Topic 2: How Fears Form – Via Pavlovian conditioning and one-trial learning; isolated events (e.g., embarrassment) or accumulated stresses create broad fears, linking sensory inputs to dopamine/reward pathways for anticipation and memory.
• Topic 3: Extinguishing Fears – Fears can't b
