The Science of Fear and the Autonomic Nervous System
09:42 - 19:58 (10:15)
The parasympathetic branch of the autonomic nervous system is involved in the calming nervous system and can be leveraged to extinguish the fear response and replace it with non-fearful associations, making it possible to undo the fear response. Autonomic nervous system controls things like digestion, urination, sexual behavior, stress, and sleep.

Our body has reflexes that cause us to lift our foot up when we step on something sharp, and similarly, there is a reflex within our spinal cord that causes us to lift up one foot and extend the other one towards the ground when we sense a threat, activating neural circuits associated with fear responses and shutting down those associated with being calm.
