Magic mushrooms for science! Dr. Natasha Mason, psychopharmacologist at Maastricht University, joins Science Decoded with a new study on psilocybin. After defining the term creativity, researchers measured the brain activity of participants under the influence of psilocybin using fMRI machines. How does brain activity change when on psilocybin? Does the brain create more or better cognitive connections? How does creativity change during and after use?
