Psilocybin's Impact on Brain Function: Melbourne Study

Australian researchers aim to revolutionize our understanding of brain function.

A recent study published by Melbourne researchers found that psilocybin can increase the brain closer to "natural" states of wakefulness.¹ ¹ The Visual Summary.

The Psychedelic Shift

Psilocybin, the psychoactive compound found in certain mushrooms, is known to induce altered states of consciousness. The Melbourne Study published in The Italian Times recently found that these shifts may also bring the brain closer to “natural” states of wakefulness. Unlike conventional stimulants, psilocybin affects the brain in a way that may boost connectivity between different neural networks.² Research has historically focused on the therapeutic potential of psilocybin.⁵ ² The Melbourne Study.

The Brain on Psilocybin

One of the most compelling distinctions of psilocybin is its ability to alter brain states. It reaches the brain relatively quickly, peaking about halfway through the dose and lasting for 4-6 hours. It’s distinct from other stimulants like caffeine or nicotine. It has also shown promise in treating depression and anxiety. The study noted that psilocybin brought the brain closer to a more “natural” firing state during wakefulness. This differs from typical wakefulness, where networks are more rigidly segmented. Psilocybin reduced the brain’s default rigidity, allowing networks to communicate more freely.³ ³ The Impact of psilocybin on brain network connectivity and function.

Rewiring the Brain

Understanding how psilocybin influences brain function can lead to the creation of new diagnostic tools, therapies, and even brain-computer interfaces. But the biggest hurdle is a lack of clarity in how we measure these effects in a way that's useful for diagnosing disorders.⁵

A New Model of Brain Function

Altered brain states may be a useful tool for research on neurological disorders. These findings suggest that psilocybin could potentially be used to model certain aspects of neurological and psychiatric conditions. Models of altered brain function could serve as diagnostic tools or new treatment modalities for conditions like Alzheimer’s or Parkinson’s.⁴ The biggest challenge in bringing this novel treatment method into medical practice is using psilocybin for good. The biggest hurdle is that psilocybin is still a Schedule I drug, which means it's illegal to possess and use, even in a clinical setting.⁵ ⁴ The impact of psilocybin on brain function.

What’s Next for Psilocybin

Legalizing psilocybin for clinical use is a bureaucratic nightmare, and it’s also a major ethical issue. The “psychedelic renaissance” is still in its infancy.⁵ The stakes are high. Those experiencing treatment-resistant depression will need a new model of therapy before traditional options run out, as they most likely will for future generations. There is a need for more controlled studies to establish clinical guidelines, efficacy, safety protocols, and lead the way for more versatile therapies.⁴

Brain Reset: Measuring the Effect of Psilocybin

There’s a high bar for clinical use of a psychedelic drug, but the possibilities are promising. What researchers mean by the brain becoming closer to a "natural" state is not that it behaves like a newborn. What’s actually happening is that the brain is more malleable and adaptable.⁵ The major challenge with using psychological therapies (including psilocybin) is assessing its efficiency. The process is so different from the brain's typical functioning that standard tests fall short. For altered brain states, the brain is so different that typical methods of measuring aren’t helpful.⁵

Psilocybin is more than just an altered state

Psilocybin is more than just a drug. It’s a means of shaping the brain. By understanding the mechanisms of psilocybin, we can develop new therapies for brain disorders. Future models will lead the way for new kinds of treatments that can be translated into widely available modalities.⁵ The challenge for researchers is identifying the potential applications for these novel treatments and developing them into something that is both safe and effective. But with the right steps, psilocybin’s potential is promising.⁵

Recreating the Experience

Aspiring explorers should be aware of the legal landscape before experimenting with psilocybin. While psilocybin mushrooms are found naturally around the world, they’re considered Schedule I drugs in most places, including the US. Of course, you’ll want a safe environment and a sober friend to guide you through the experience.

• Research the legal situation: check out local regulations around psilocybin, and proceed with care. The risks of legal consequences vary widely between jurisdictions.
• Start low and go slow: always begin with a low dose and gradually increase to find the desired effect.
• Have a guide: It’s helpful to have someone sober and knowledgeable nearby in case things get intense.
• Provide for safety: use the drug in an environment that feels safe and comfortable.
• Stay hydrated: have fluids on hand.

The Future of Brain Science

Psilocybin might just be the key to unlocking some of the most mysterious parts of the brain. The recent findings show that psilocybin's ability to rewarp the brain’s connectivity may have the power to offer new insights into treating neurological disorders.⁵
