A study suggests that psilocybin, a compound found in magic mushrooms, may rewire the brain to break depressive cycles. The research indicates that a single dose of psilocybin can induce lasting brain changes, potentially relieving chronic pain and depression by targeting specific brain circuits. However, the effects of psilocybin on the brain may also depend on other factors, such as estrogen levels, which could influence how the brain reacts to the psychedelic compound.
