19. Neurochemistry: The Molecules of Belief
Placebo responses are rooted in neurochemical changes within the brain. Studies have shown that belief in treatment can increase levels of endorphins and dopamine, the very molecules involved in pain relief and pleasure.
This discovery bridges the gap between psychology and biology, revealing how expectations can physically alter our brain chemistry. For a deeper dive into the science behind these mechanisms, see Frontiers in Neuroscience.
