Magic mushrooms, or mushrooms containing psilocybin, are known to have profound emotion-, perception-, and cognition-altering properties. While the exact mechanisms of their effects are still being studied, psilocybin has been shown to increase neuroplasticity by sprouting new dendrites, or branches, between neurons, thereby increasing communication between brain cells. This may be how psilocybin is able to ease symptoms of depression, anxiety, and more.

How psilocybin may rewire the brain
Psilocybin, the psychedelic compound found in magic mushrooms, has been found to rewire the brain in depressed people and alleviate symptoms of anxiety, anorexia, obsessive-compulsive disorder, and various forms of substance abuse.
Psilocybin improves connections between different regions of the brain, allowing individuals to escape excessive rumination and self-focus. A study by scientists at UC San Francisco and Imperial College London found that psilocybin reduced connections within brain areas that are tightly connected in depression. Another study by Yale researchers found that a single dose of psilocybin given to mice prompted an immediate and long-lasting increase in connections between neurons.
Psilocybin and other psychedelics increase neuroplasticity, allowing the brain to transition from one state to another much more readily. This means that psilocybin can help to shake up the brain and allow individuals to see things in a more positive way, laying down new, positive circuits. This is supported by the fact that psilocybin affects 5-HT2A receptors, which are plentiful in brain networks that become overactive in depression. By briefly disrupting these connections, psilocybin allows them to reform in new ways in the following days and weeks.
However, it is important to note that the effects of psilocybin on the brain are not yet fully understood, and there are potential risks associated with its use. Researchers are still working to understand how psilocybin impacts the wider dynamics of brain activity and how long the beneficial results may last. Additionally, while psilocybin can enhance neuroplasticity, it is unclear whether this makes individuals more vulnerable to the encoding of traumatic events. Furthermore, psilocybin can have side effects such as increased blood pressure, heart rate, and body temperature, and it may not be suitable for everyone, especially those currently taking SSRIs.

The antidepressant qualities of magic mushrooms
Magic mushrooms, or "shrooms", have been used by indigenous cultures in religious or spiritual rituals for generations. They are also a popular recreational drug. The active compound in magic mushrooms is called psilocybin, a naturally occurring psychedelic.
In recent years, psilocybin has been studied as a potential treatment for depression. Researchers have found that psilocybin can produce perceptual changes, altering a person’s awareness of their surroundings and of their thoughts and feelings. Small clinical trials have shown that one or two doses of psilocybin, given in a therapeutic setting, can make dramatic and long-lasting changes in people suffering from treatment-resistant major depressive disorder.
The antidepressant qualities of psilocybin may be due to its ability to spur the growth of neural connections, specifically dendrites, which look like branches on a tree. These new dendrites increase communication between cells and allow for the creation of new circuits in the brain. This process, known as neuroplasticity, may help people with depression to see things in a more positive way and lay down more positive pathways.
While the antidepressant effects of psilocybin are promising, it is important to note that it should be used in a controlled setting with proper monitoring and support. The potential long-term side effects and serious rare side effects of psilocybin use are still not fully understood, and negative outcomes such as a "bad trip" are possible. However, when used in a therapeutic setting with dedicated psychological support, psilocybin has been found to be at least as effective as leading antidepressant medications.

The role of neuroplasticity in reshaping the mind
Neuroplasticity, or brain plasticity, is the brain's ability to change and adapt due to experience. It involves the nervous system's ability to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections after injuries, such as a stroke or traumatic brain injury. This ability allows the brain to adjust in response to new experiences, learning, emotions, and even injuries.
The brain's ability to change is not limited to childhood, as was previously believed. Neuroplasticity occurs throughout our lives, with the potential for adaptation remaining in adult brains. This adaptability allows us to learn new skills, form new connections, and recover from brain-based injuries and illnesses. For example, in children with blindness, the brain demonstrates increased connectivity and reorganized neurocircuits, allowing for greater utilization of information received from other senses.
Practices that promote positive thinking and emotional regulation, such as mindfulness, gratitude, or therapy, can lead to measurable changes in brain structure. The prefrontal cortex, responsible for decision-making and emotional regulation, becomes stronger, while areas associated with stress and fear, like the amygdala, become less active. These changes not only improve our emotional and mental landscape but also physically alter our brain's structure for the better.
Psychedelic substances, such as psilocybin, the active compound in "magic mushrooms," have been found to increase neuroplasticity. They promote the growth of dendrites, which help build and solidify new circuits in the brain, allowing for the formation of more positive pathways. Small clinical trials have shown that one or two doses of psilocybin, in a therapeutic setting, can lead to significant improvements in people with treatment-resistant major depressive disorder.
While neuroplasticity can bring about positive changes, it is important to recognize that reshaping the mind is not always beneficial. Negative influences, such as substance use, disease, or trauma, can also impact brain plasticity. Therefore, a balanced approach is necessary, leveraging neuroplasticity to enhance our mental well-being, break free from harmful thought patterns, and learn new skills while being mindful of potential pitfalls.

The effects of psilocybin on brain regions
Psilocybin, the active compound in "magic mushrooms", has been studied for its effects on the brain and its potential therapeutic benefits. Research has shown that psilocybin can cause significant changes in brain function and connectivity, particularly in the following regions:
Cerebral Cortex
The cerebral cortex is involved in various cognitive functions, including sensory processing, motor control, and higher-level tasks such as language and decision-making. Psilocybin has been found to alter activity and connectivity in this region, leading to changes in perception and cognitive processes.
Thalamus
The thalamus acts as a relay station for sensory information, regulating consciousness, sleep, and alertness. Psilocybin's impact on the thalamus could contribute to the altered states of consciousness and sensory experiences often associated with psychedelic trips.
Hippocampus
The hippocampus plays a crucial role in memory, spatial navigation, and emotional regulation. Psilocybin has been shown to affect hippocampal circuits, particularly those involved in the perception of self and time. These effects may underlie the therapeutic potential of psilocybin in treating mental health disorders such as depression and post-traumatic stress disorder (PTSD).
Cerebellum
The cerebellum is responsible for coordinating movement and balance, but it also has roles in cognitive and emotional functions. Psilocybin-induced changes in the cerebellum could contribute to the altered movement and coordination experienced during psychedelic trips, as well as potential cognitive and emotional effects.
While the exact mechanisms are still being elucidated, psilocybin appears to increase neuroplasticity, promoting the growth of new neural connections and dendrites. This may underpin its therapeutic benefits, as it allows for the formation of new circuits and the potential overwrite of maladaptive pathways associated with mental health disorders.
Overall, psilocybin's effects on these brain regions highlight its potential as a therapeutic tool, but further research is needed to fully understand its long-term impacts and optimize its use in clinical settings.

The therapeutic potential of psilocybin
Psilocybin, the active compound in "magic mushrooms," has been used for thousands of years in religious and spiritual ceremonies. It has also been studied for its therapeutic potential in treating neuropsychiatric conditions.
Psilocybin is a naturally occurring psychedelic compound found in some mushrooms. It produces mind-altering and reality-distorting effects, known as hallucinations, once ingested. While the molecular mechanisms of action are not yet fully understood, psilocybin binds with high affinity to 5-HT2A serotonin receptors, which are densely located in areas of the brain responsible for mood and anxiety disorders.
Additionally, psilocybin may facilitate the growth of new neural connections. A single dose of psilocybin given to mice resulted in an immediate and long-lasting increase in the number and strength of neuronal connections. This finding suggests that psilocybin may have the potential to treat depression by promoting neuroplasticity and the formation of new circuits in the brain.
While psilocybin shows therapeutic potential, it is important to note that it should be used with caution. The psychedelic effects of psilocybin can be intense, and without a mediating positive influence, individuals may be left to the mercy of their imagination, potentially leading to negative experiences. Furthermore, the historical association of psilocybin with the "hippie" counterculture movement resulted in a lingering negative stigma that hindered scientific research and innovation in psychedelic therapeutics for many years.

Frequently asked questions
Psilocybin, the active compound in "magic mushrooms", has been studied as a potential treatment for depression and anxiety. It has been shown to increase neuroplasticity, which can help people maintain insights gained while on psilocybin and form new, positive neural pathways.
While on psilocybin mushrooms, one may experience enhanced neuroplasticity, which can allow for the formation of new neural pathways. To build new pathways, one must first identify the behaviour or thought pattern they wish to change. While under the influence of psilocybin, one may be able to view this behaviour or thought pattern in a new light and form a novel perspective. Following the experience, one can then work to solidify this new perspective through repeated exposure and practice, thereby forming a new neural pathway.
While psilocybin has been shown to have therapeutic potential, it is not without risks. Psychedelics can alter one's consciousness and perception, which may lead to a negative experience if not properly guided. Additionally, researchers are still working to understand the long-term effects of psilocybin on the brain. It is important to approach the use of psilocybin with caution and, ideally, under the supervision of a licensed guide or therapist.
