Practical Magic: The Therapeutic Effects of Psilocybin on Affect Regulation An interesting new development is taking place in pharmacological research. Neuroscientists are picking up where they left off in 1971 and continuing their research on the psychotropic effects of psilocybin‚ many of which have therapeutic value. There are many ways in which psilocybin works‚ yet its main mechanism of action seems to be reducing activity in the amygdala via its effects on the serotonergic system. It is through

However Julian disagrees with this statement and says depression may be due to neuron damage rather than a neurotransmitter reduction. The problem with this approach is that it implies correlation and not causation‚ there may be a link but something else could be causing both depression and low serotonin.
