A long-ridiculed theory about humankind's early leap of consciousness is revived.
- Terence McKenna first proposed psychedelic mushrooms as the trigger for our rapid cognitive evolution.
- McKenna's theory was called the "Stoned Ape Hypothesis."
- The hypothesis is being revisited as a possible answer to a vexxing evolutionary riddle.
A new study shows that psilocybin can "reset" the brain and put depression in the rear-view mirror.
Depression is one of the most common medical conditions afflicting the world today. However, despite its familiarity, treatments are still wanting. Most common antidepressants are considered to have a low to moderate effect on typical cases. The search for more effective ways to treat depression is of great importance—depression costs a trillion dollars (!) in lost productivity each year and takes the lives of 2-7% of those who suffer from it.
A new study suggests that an effective drug has been under our noses for some time... magic mushrooms.
In a study from the Imperial College in London, nineteen patients were given two incrementally larger doses of psilocybin a week apart. MRI scans were taken on the brains of the patients before and after the trips. It was found that the drugs had the effect of reducing and then increasing the amount of blood flow to and changing the activity levels of differing regions of the brain, some of which are associated with depressive symptoms.
