“You also see the opposite of that - local networks in the brain that normally interact with each other quite a bit suddenly communicate less.” “When someone’s on psilocybin, we see an overall increase in connectivity between areas of the brain that don’t normally communicate well,” Johnson said. “One of the most interesting things we’ve learned about the classic psychedelics is that they have a dramatic effect on the way brain systems synchronize, or move and groove together,” said Matthew Johnson, a professor in psychedelics and consciousness at Johns Hopkins Medicine. With psychedelics such as psilocybin and LSD, however, scientists can see changes in brain neuron connectivity in the lab “within 30 minutes,” said pharmacologist Brian Roth, a professor of psychiatry and pharmacology at the University of North Carolina at Chapel Hill.

Yet it can take weeks for improvement to occur, experts say, if the drugs even work at all. Treatment typically involves selective serotonin reuptake inhibitors, or SSRIs, which boost levels of serotonin available to brain cells. People with depression or anxiety often have low levels of serotonin, as do people with post-traumatic stress disorder, cluster headaches, anorexia, smoking addiction and substance abuse. “The data are strong from depression to PTSD to cluster headaches, which is one of the most painful conditions I’m aware of,” said neurologist Richard Isaacson, director of the Alzheimer’s Prevention Clinic in the Center for Brain Health at Florida Atlantic University. Psilocybin, which the intestines convert into psilocin, a chemical with psychoactive properties, is also showing promise in combating cluster headaches, anxiety, anorexia, obsessive-compulsive disorder and various forms of substance abuse. Small clinical trials have shown that one or two doses of psilocybin, given in a therapeutic setting, can make dramatic and long-lasting changes in people suffering from treatment-resistant major depressive disorder, which typically does not respond to traditional antidepressants.īased on this research, the US Food and Drug Administration has described psilocybin as a breakthrough medicine, “which is phenomenal,” Stamets said. “Psilocybin mushrooms are nonaddictive, life-changing substances.” These are no longer ‘shrooms.’ These are no longer party drugs for young people,” Stamets told CNN. Yet leading mycologist Paul Stamets believes it’s time for fans of psilocybin mushrooms to leave such childish slang behind. Shrooms, Alice, tweezes, mushies, hongos, pizza toppings, magic mushrooms - everyday lingo for psychedelic mushrooms seems to grow with each generation.
