HOW SHROOMS AFFECT THE BRAIN #SHORTS
How does magic mushrooms affect the human brain?
Some people say they make you go crazy, others say they give us more access to the unconscious.
But what does current neuroscience say?

Psilocybin works by activating serotonin receptors, most often in the prefrontal cortex. This part of the brain affects mood, cognition, and perception.
Professor David Nutt, from the Imperial College London, said: "Psychedelics are thought of as 'mind-expanding' drugs so it has been assumed that they work by increasing brain activity, but surprisingly, we found that psilocybin actually decreased certain brain activity, particularly the default mode network, which is commonly associated with the “ego” that keeps our world orderly.’
This could explain the commonly reported experience of “ego dissolution”.
Imperial’s Centre for Psychedelic Research analysed fMRI scans of 2 groups.
One group was given psilocybin; the other, a SSRI antidepressants.
"The effect seen with psilocybin is consistent across two studies, related to people getting better, and was not seen with a conventional antidepressant."
Professor Robin Carhart-Harris
Studies showed increased brain connectivity not just during their treatment, but up to three weeks afterwards.
The intensity of the effects reported by the participants, including visions of geometric patterns, unusual bodily sensations and altered sense of space and time, correlated with a decrease in oxygenation and blood flow in certain parts of the brain.
Johns Hopkins psychologists reported that participants who received psilocybin said they felt more open, more imaginative, and more appreciative of beauty.
