You really don’t have a clue about what you just posted, do you?
- Those images do not show serotonin in brain, but serotonin axons. They come from a very famous study done in 1999 by Hatzidimitriou G, McCann UD, Ricaurte GA.
- Those images represent slices of monkey brains, and not human brains.
- Those monkeys were given extreme doses of MDMA. 5 mg/kg 2 times a day during 4 days. A recreational dose of MDMA is about 1mg/kg so about 5 times lower. It’s like giving someone a few bottles of whisky every day during 4 days. Of course it will cause some form of damage. Even common substances like salt will kill you at extreme doses but we eat it every day on small doses.
- And even with those very extreme doses no brain cells were damaged, only axons.
