Magic Mushrooms Might Rebalance the Brain - Study * 2
    #27110548 - 12/27/20 11:06 AM (3 years, 1 month ago)

Mostly common knowledge around these parts. But, it's interesting none-the-less. Link to article

Here's the link to the PNAS paper. You can download the pdf for free.


Quote:


In a study published in April, researchers created a realistic whole-brain model, also known as a "whole-brain connectome" — basically, a picture of all the neurons ticking away in the brain and the different neurotransmitters that they are constantly lugging around. They used this to model how the human brain looks on psilocybin.

The team incorporated images of the brains of the study’s nine participants, who had been injected with psilocybin (or a saline placebo).

Using the model allowed the scientists to study exactly how psilocybin affects the brain. The team saw that, when psilocybin was introduced, it disrupted networks in the brain — they became “destabilized” — and forced the neurotransmitters to find new pathways between brain cells.

"We wanted to investigate the role of neurotransmission in dynamically changing the activity in whole-brain networks — and how this changes neurotransmitter release in return," Morten Kringlebach, the study's first author and a senior research fellow at the University of Oxford, told Inverse.

This study hints that psilocybin works its magic by “rebalancing” the brain. Psilocybin’s most promising skill, its effectiveness in alleviating treatment-resistant depression, is thought to be by virtue of the activation of serotonin 2A (5-HT2A) receptors.

The promise of psilocybin, and psychedelic drugs writ large, as powerful potential treatments for chronic mental illnesses such as depression, anxiety, or addiction, seems to grow only more realistic as time passes and research sophisticates. Figuring out how exactly they work on the brain will be crucial to harnessing their powers.

"This new model will give us the much needed, causal tools for potentially designing new interventions to alleviate human suffering in neuropsychiatric disorders," Kringlebach told Inverse.

Sounds like by having psilocybin force the neurons to find new pathways to communicate within the brain is like psychological exercise. Interesting. This might be why it is good at treating TRD, because it may allow the individual to find out how to fix it...or maybe the brain finds a way with the psilocybin. The pharmacology of psychedelics is fascinating.
