The main purpose of the imaging study is to determine how LSD works on the human brain to produce its characteristic psychological effects. This question has never been addressed before. Understanding more about the physiological effects of LSD will help us shed light on potential medical interventions as well as help us learn more about consciousness. In many respects how the brain works is still a mystery. By researching how psychedelics work, we will be a step closer to understanding how specific areas of the brain are affected to induce certain psychological effects.
