A new study found that people's responses to placebo treatments are linked to their brain's dopamine activity, particularly in the nucleus accumbens. The study used two types of brain scans to investigate this phenomenon and suggests that individual expectations play a significant role in determining the effectiveness of placebos.
Scientists pinpointed the nucleus accumbens as key player in the placebo effect, which influences treatment efficacy through expectation. The study found that anticipation of pain relief triggers dopamine release from NAC.
