A 2019 study was conducted wherein patients suffering from depression were scanned using an MRI, to show the difference in brain activity with and without the presence of psilocybin. What was discovered is that after psilocybin is administered, the brain’s neural pathways experienced a rewiring. New neuro-connections began appearing, linking regions of the brain that did not previously communicate. This is all thanks to psilocybin being attractive to our serotonin receptors. The chemical compound is absorbed offering a dopamine response, which is directly responsible for feelings of happiness and contentment.
