Magic mushrooms have long been touted as a recreational drug, but recent studies have shown that psilocybin, the active compound in magic mushrooms, may be able to reshape brain cells and treat mental illnesses such as depression, anxiety, and PTSD. While the exact mechanism is still unclear, researchers have found that psilocybin increases the connections between neurons and allows the brain to transition between states more readily. This suggests that psilocybin could have unique advantages as a treatment for mental illnesses, as it acts differently in the brain compared to traditional SSRIs. Small clinical trials have shown that one or two doses of psilocybin, administered in a therapeutic setting, can lead to dramatic and long-lasting changes in people with treatment-resistant major depressive disorder.

What You'll Learn
How psilocybin spurs growth of neural connections
Psilocybin, the active compound in "magic mushrooms," has been studied for its potential to treat depression and other mental illnesses. While the exact mechanism of its effects is still being elucidated, recent studies have provided insights into how psilocybin may spur the growth of neural connections.
Psilocybin is a serotonergic psychedelic that activates serotonin receptors on brain cells. Serotonin plays a crucial role in regulating mood, and people with depression often have low serotonin levels. By activating serotonin receptors, psilocybin reduces the energy required for the brain to switch between different activity states, making it easier for the brain to transition from one state to another. This "flattening" effect may contribute to the drug's therapeutic potential.
In a study conducted on mice, a single dose of psilocybin led to a rapid and persistent increase in spine density and size in the frontal cortex, resulting in stronger neuronal connections. This structural remodeling occurred within 24 hours and lasted for at least one month. The increased spine density and size suggest that psilocybin promotes the growth of dendrites, which are the branches of brain cells that receive signals from other neurons.
The growth of dendrites helps to build and solidify new circuits in the brain, allowing for the formation of more positive pathways. This process may explain how psilocybin could help individuals with depression maintain positive insights and integrate new experiences. Additionally, psilocybin has been shown to increase neuroplasticity, which refers to the brain's ability to form new neural connections and adapt to new situations.
While the research on psilocybin is promising, it is important to note that its effects are not universal, and more research is needed to fully understand its mechanism of action and long-term effects. Furthermore, the use of psilocybin should be approached with caution and under the guidance of medical professionals, as it can have significant psychological effects.

The impact of psilocybin on dendritic spines
Psilocybin, the psychoactive compound found in magic mushrooms, has been the subject of numerous studies investigating its impact on the brain and its potential therapeutic benefits. One notable area of interest is the effect of psilocybin on dendritic spines, which are small protrusions found on brain cells that play a crucial role in receiving signals from other neurons.
Research has shown that psilocybin induces rapid and persistent growth of dendritic spines in the frontal cortex of mice. Specifically, a single dose of psilocybin led to an approximate 10% increase in spine size and density, with the structural remodelling occurring within 24 hours and lasting for at least one month. This growth was driven by an elevated spine formation rate, indicating that psilocybin promotes the creation of new dendritic spines. Interestingly, the effects of psilocybin on spine density were more pronounced in female mice compared to male mice.
Furthermore, psilocybin activates serotonin receptors on brain cells, reducing the energy required for the brain to switch between different activity states. This discovery offers insight into the mechanism of psilocybin's therapeutic effects and how it may impact the wider dynamics of brain activity. While more research is needed to fully understand the impact of psilocybin on the mammalian brain, these initial findings suggest that psilocybin has the potential to be a powerful tool in the treatment of mental illnesses.

The potential of psilocybin to treat depression and anxiety
Psilocybin, the psychoactive compound found in magic mushrooms, has been the subject of numerous studies investigating its potential to treat depression and anxiety.
A 2016 study found that psilocybin therapy was associated with a significant reduction in symptoms of anxiety and depression in people undergoing cancer treatment. The treatment was also linked to increased optimism and better quality of life. Notably, 71-100% of participants described psilocybin-assisted therapy as one of the most personally meaningful and spiritually significant experiences of their lives.
Another study conducted by Johns Hopkins Medicine researchers found that psilocybin-assisted therapy, when combined with supportive psychotherapy, may offer substantial antidepressant effects that last at least a year for some patients. The treatment resulted in large decreases in depression severity, with stable rates of response and remission throughout the follow-up period.
The potential efficacy of psilocybin in treating depression may be attributed to its ability to activate serotonin receptors on brain cells, specifically the serotonin 2A receptors. This activation reduces the energy required for the brain to switch between different activity states, allowing for more efficient transitions between brain states. Additionally, psilocybin has been found to induce rapid and persistent growth of dendritic spines in the frontal cortex, which are responsible for receiving signals from other brain cells. This structural remodelling occurs quickly within 24 hours and can last for at least a month, suggesting the potential for long-term benefits.
While the research on psilocybin shows promise, it is important to recognize that it can also produce unwanted effects, such as intense feelings of anxiety, fear, paranoia, delusions, and hallucinations, commonly referred to as a "bad trip." As a result, it is crucial that the use of psilocybin for therapeutic purposes is supervised by trained mental health professionals and accompanied by preparatory meetings to ensure a safe and controlled environment.

Psilocybin's ability to reshape brain cells
Psilocybin is a naturally occurring compound found in some mushrooms. It has been studied as a potential treatment for depression and anxiety. While the exact mechanism of its effects is still unclear, recent studies have provided new insights into how it works in the brain.
Brain Cell Regeneration
Psilocybin has been found to induce the growth of dendritic spines in the frontal cortex of mice. This growth was rapid, occurring within 24 hours, and persistent, lasting for at least one month. The increase in spine size and density led to stronger connections between neurons. These structural changes may be how the brain stores new experiences.
Brain Cell Reconnection
Psilocybin has also been shown to affect the way brain cells connect and communicate. In a study conducted by Morten Kringleback of the University of Oxford, brain images were taken of individuals injected with psilocybin or a placebo. The images revealed that psilocybin destabilized well-trodden neural pathways, causing neurotransmitters to take new roads to different destinations. This suggests that psilocybin allows the brain to tap into new networks and form new connections.
Therapeutic Potential
The ability of psilocybin to reshape brain cells has important therapeutic implications. Small clinical trials have shown that one or two doses of psilocybin in a therapeutic setting can lead to dramatic and long-lasting changes in people with treatment-resistant major depressive disorder. Psilocybin may also be effective in treating other neuropsychiatric disorders such as PTSD, addiction, and anxiety.
While more research is needed to fully understand the effects of psilocybin, its potential to reshape brain cells offers new hope for the treatment of various mental health conditions.

The differences in how psychedelics act in the brain
Psychedelics like psilocybin and DMT can act inside brain cells, and they hold promise as treatments for mental illnesses like depression, anxiety, and post-traumatic stress disorder (PTSD). While the exact mechanism of their action is still being studied, researchers have found that these substances can get inside brain cells and cause them to regrow their connective links.
Brain cells have branches called dendrites that are responsible for receiving signals from other brain cells. These dendrites play a crucial role in brain function, and damaged dendrites have been linked to various brain disorders, including neurodegenerative diseases like Alzheimer's and psychiatric illnesses like depression. A single dose of psilocybin has been found to lead to a rapid and persistent increase in spine size and density in the frontal cortex, with structural remodelling occurring within 24 hours and lasting for at least a month.
Additionally, psychedelics like LSD and psilocybin activate serotonin receptors on brain cells, reducing the energy needed for the brain to switch between different activity states. This results in a "'flattening'" of the brain's dynamic landscape, making it easier for the brain to transition from one state to another. These drugs also cause acute changes in how people perceive time, space, and their sense of self.
It is important to note that while psychedelics show potential in treating mental illnesses, they should not be used for self-medication without the supervision of trained mental health experts. Researchers are still working to understand the unique advantages of psychedelics compared to traditional antidepressants, and more studies are needed to fully comprehend the relevance of these findings in humans.
