Magic mushrooms, or psychedelic mushrooms, have been used for centuries in various cultures for their mind-altering effects. The active compound in these mushrooms is called psilocybin, and it has been the subject of scientific study to understand its effects on the brain and its potential therapeutic benefits. Psilocybin has been found to cause significant changes in brain activity, including desynchronization and reduced functionality in certain areas. These changes are reflected in the distorted sense of self, space, and time that people often experience during a trip. Recent studies have also shown that psilocybin may have long-lasting positive effects on mental health disorders such as depression, anxiety, and post-traumatic stress disorder (PTSD). However, more research is needed to fully understand the neurobiological effects of psilocybin and other psychedelic substances.

What You'll Learn
Psilocybin desynchronizes the human brain
Psilocybin, a psychedelic substance found in certain mushrooms, has been the subject of numerous studies investigating its effects on the human brain. Research has shown that psilocybin produces rapid and persistent therapeutic effects in human clinical trials.
One notable effect of psilocybin is its ability to disrupt functional connectivity (FC) in the brain. FC refers to how activity in different regions of the brain is correlated. Psilocybin has been found to massively disrupt FC in the cortex and subcortex, causing more than three times greater change than methylphenidate, a control compound. This disruption of FC is driven by brain desynchronization across different spatial scales.
The acute effects of psilocybin include distortions in space-time perception and ego dissolution. These effects have been visualized through functional magnetic resonance imaging (fMRI) scans, which show a profound disturbance in brain activity patterns after a dose of psilocybin. The brain regions most affected by psilocybin include the cerebral cortex, thalamus, hippocampus, and cerebellum.
Psilocybin has also been found to induce neuroplasticity in the cortex and hippocampus, particularly in the anterior and middle hippocampus, which is associated with the self and the present moment. This neuroplasticity is thought to be necessary for the rapid antidepressant-like effects observed in animal models. In humans, psilocybin has been shown to produce the largest changes in the default mode network (DMN), which is associated with neuropsychiatric disorders and the sense of self.
The long-term effects of psilocybin on the human brain are still being studied. While most brain activity returns to normal within days, some changes, such as reduced FC between the DMN and the hippocampus, can last for several weeks or even months. The persisting effects of psilocybin include increased expression of genes related to synaptic plasticity and increased growth of neurites and synapses.

Psilocybin disrupts brain networks
Psilocybin, the psychedelic compound in magic mushrooms, has been found to massively disrupt functional connectivity in the cortex and subcortex, causing a significant disturbance in brain activity patterns. This disruption is believed to be responsible for the mind-bending effects of the drug, including distortions in perception, sensory experiences, mood, and thought processes.
Functional connectivity (FC) refers to the correlation between activities in different regions of the brain. Psilocybin induces major changes in FC, causing brain activity to become less synchronized and leading to reduced distinction between brain networks that typically exhibit distinct activity. These changes are particularly pronounced in the default mode network, which is associated with internal thoughts, and an individual's sense of time, space, and self.
Research has shown that psilocybin disrupts the brain's dynamic landscape, making it easier for the brain to transition between different activity states. This is achieved by activating serotonin 2a receptors, which are thought to be the main targets of psilocybin and similar psychedelic drugs like LSD. By lowering the energy barriers to state transitions, psilocybin reduces the brain's energy requirements for switching between states.
The impact of psilocybin on brain networks is profound and has been visualized through functional magnetic resonance imaging (fMRI). During a psilocybin trip, the brain's normally stable patterns are temporarily scrambled, resulting in a loss of individuality and a sense of "ego dissolution." This disruption in brain networks may contribute to the therapeutic effects observed in the treatment of mental health conditions such as depression, anxiety, and post-traumatic stress disorder (PTSD).
While the full extent of psilocybin's impact on the brain is still being explored, its ability to disrupt brain networks offers valuable insights into the development of potential treatments for various brain and mental health disorders. The neurobiological effects of psilocybin are complex and highlight the importance of understanding how psychedelic substances interact with the brain's dynamics and functional connectivity.

Psilocybin's therapeutic effects
Psilocybin, the psychedelic compound found in magic mushrooms, has been the subject of numerous studies investigating its therapeutic effects on the brain. These studies have found that psilocybin can cause profound changes in brain activity, particularly in the default mode network, which is associated with internal thoughts and an individual's sense of time, space, and self.
One of the most notable effects of psilocybin is its ability to desynchronize or disrupt the brain's functional connectivity. This refers to the way different regions of the brain interact and exchange information. Psilocybin has been found to cause a massive disruption in functional connectivity, with changes more than three times greater than those caused by a control compound. This desynchronization leads to a reduction in the normal distinctions between brain networks, resulting in a temporary loss of individuality and a sense of "ego dissolution".
The therapeutic effects of psilocybin have been observed in the treatment of mental health disorders such as depression, anxiety, post-traumatic stress disorder (PTSD), and cluster headaches. In some cases, a single dose of psilocybin has been found to produce rapid and persistent therapeutic effects, even after the acute effects of the drug wear off. However, it is important to note that the effects of psilocybin are highly individualized, and the same dose may have varying outcomes for different people.
Microdosing is another approach that has gained popularity, where individuals consume a tiny amount of psilocybin (typically 0.1 to 0.3 grams) several times a week to maintain brain health and enhance creativity. While some people have reported positive benefits from microdosing, it is important to approach these substances with caution and under the supervision of trained mental health experts.
Ongoing research continues to explore the potential of psilocybin in treating brain and mental health disorders. By understanding how psilocybin affects the brain, scientists and doctors aim to harness its therapeutic potential and develop psilocybin-based therapies to alleviate mental distress and improve overall brain health.

Microdosing with mushrooms
Some people who microdose with mushrooms report positive experiences and improvements in their lives. For example, a group of mothers who microdose have shared their experiences, claiming that it helps them manage stress and anxiety associated with modern motherhood. They assert that microdosing gives them more patience, improves their ability to cope with challenges, and enhances their overall well-being. These mothers have formed support groups, both online and in-person, to share their experiences and connect with others who are also microdosing.
While the anecdotal evidence from microdosers suggests positive outcomes, researchers caution that more scientific research is needed to fully understand the effects of psilocybin microdosing on the brain and overall health. Some studies have found that psilocybin causes major changes in functional connectivity within the brain, particularly in areas involved in the default mode network, which governs an individual's sense of space, time, and self. However, the long-term effects of these changes are still unknown, and more research is needed to determine the safety and efficacy of microdosing with mushrooms.

Psilocybin's effects on serotonin receptors
Psilocybin, the psychedelic compound in mushrooms, has been found to have a profound effect on the human brain. Research has shown that psilocybin disrupts the normal functioning of the brain, causing a "desynchronization" effect. This means that brain activity becomes less coordinated and more random, leading to altered perceptions of time, space, and self.
One of the key ways psilocybin exerts its effects is through its action on serotonin receptors, specifically the serotonin 5-HT2A receptor. Serotonin is a neurotransmitter that plays a crucial role in regulating mood, cognition, and various physiological processes. Psilocybin acts as an agonist at the 5-HT2A receptor, stimulating it and leading to increased serotonin activity. This activation of the 5-HT2A receptor is specifically responsible for the hallucinogenic effects of psilocybin and other serotonergic psychedelics.
The impact of psilocybin on serotonin receptors has been found to be long-lasting, with some changes persisting for weeks after ingestion. This has led to the exploration of psilocybin as a potential treatment for various psychiatric conditions, including depression, anxiety, and post-traumatic stress disorder (PTSD). The ability of psilocybin to induce a state of increased neuroplasticity and reduced rigidity in brain networks may contribute to its therapeutic effects.
While the activation of serotonin receptors is primarily associated with the hallucinogenic effects of psilocybin, it may also play a role in the therapeutic benefits observed. By reducing the energy barriers between different brain states, psilocybin allows the brain to transition more easily between these states. This could potentially disrupt negative thought patterns and emotional responses associated with depression and anxiety.
It is important to note that while psilocybin has shown promising results in controlled settings, it is not without risks. Certain psychiatric conditions, such as a history of psychosis or schizophrenia, are considered contraindications for psilocybin use due to the potential for adverse psychological effects. Additionally, frequent or chronic use of psilocybin may lead to cardiac fibrosis and valvulopathy due to serotonin 5-HT2B receptor activation. Therefore, while psilocybin has the potential to bring about positive changes in the brain, it should be approached with caution and under the guidance of medical professionals.
