Psilocybin desynchronizes the human brain
Psilocybin, the psychedelic compound found in magic mushrooms, has been found to desynchronize the human brain. This desynchronization is associated with the drug's therapeutic effects, which may include the treatment of mental health issues such as depression, anxiety, and PTSD.
A study conducted by Dr. Joshua Siegel at Washington University in St. Louis used functional magnetic resonance imaging (fMRI) to track changes in brain activity related to the use of psilocybin. The study found that psilocybin caused major changes in functional connectivity (FC), or the correlation of activity between different regions of the brain. These regions included the cerebral cortex, thalamus, hippocampus, and cerebellum.
Psilocybin was found to induce the largest changes in the default mode network (DMN), which is associated with our sense of space, time, and self. The drug also caused a reduction in FC between the DMN and the hippocampus, which may reflect lasting changes in hippocampus circuits involved with the perception of self. These findings suggest that psilocybin temporarily desynchronizes the brain's ability to think about the self in relation to the world.
Further research has shown that psilocybin massively disrupts functional connectivity in the cortex and subcortex, causing more than three times greater change than methylphenidate, a stimulant used to treat ADHD. These changes were driven by brain desynchronization across spatial scales and were strongest in the DMN, which is connected to the anterior hippocampus. Performing a perceptual task during psilocybin ingestion reduced the drug's impact on brain networks, suggesting a neurobiological basis for grounding or connecting with physical reality during psychedelic therapy.

Altered perception of self
Psychedelics like psilocybin, the active ingredient in magic mushrooms, can profoundly alter a person's perception of self. This effect is attributed to the drug's ability to temporarily "desynchronize" or "destabilize" the brain's default mode network, which is responsible for our sense of self in relation to the world.
During a psilocybin trip, the brain's normal patterns of activity are disrupted, leading to a sense of ego dissolution or a loss of self. This effect has been visualized through brain imaging studies, which show that psilocybin disrupts functional connectivity (FC) in the cortex and subcortex, including the hippocampus, a region involved in the perception of self. These changes are more than three times greater than those caused by a control compound, methylphenidate.
The temporary disruption of the default mode network may have therapeutic benefits for mental health disorders. Ongoing research suggests that psilocybin could be used to treat depression, anxiety, post-traumatic stress disorder (PTSD), and cluster headaches. The drug's ability to temporarily alter the brain's normal state may create an opportunity for the brain to transition to a healthier state, potentially alleviating mental distress.
While the full mechanism of psilocybin's effects is not yet understood, it is believed to work by reducing the energy barriers between different brain states. This allows the brain to transition more readily between states, which may contribute to the sense of altered self-perception and the drug's therapeutic effects.
It is important to note that the use of psilocybin and other psychedelics should be approached with caution. While they have shown promising results in controlled settings, they can also induce negative or scary experiences. Researchers strongly advise against self-medication and recommend supervision by trained mental health experts.

Rewiring the brain to ease depression and anxiety
Psychedelic mushrooms have been found to have the potential to rewire the brain and ease symptoms of depression and anxiety. Ongoing research is exploring how psilocybin, the psychedelic substance found in these mushrooms, affects the brain and how it could be used to treat mental health disorders.
Psilocybin has been shown to cause acute changes in how people perceive time, space, and the self. It does this by disrupting the communication between networks within the brain and interfering with specific brain chemicals or neurotransmitters that control different functions. This results in a "desynchronization" of brain activity, with relatively stable areas of the brain being temporarily "scrambled".
In a study conducted by Dr. Joshua Siegel at Washington University in St. Louis, functional magnetic resonance imaging (fMRI) was used to track changes in brain activity related to the use of psilocybin. The results showed that psilocybin caused significant, widespread changes in the brain's functional connectivity, with the largest changes occurring in areas involved in the default mode network. This network is usually most active when the brain is not focused on a specific task and is thought to govern people's sense of space, time, and self.
The therapeutic effects of psilocybin can last long after the acute effects of the drug wear off. In some studies, participants who were given a single dose of psilocybin showed improvements in their mental health symptoms even eight years later. While the majority of participants with chronic depression relapsed within four to five months, the lasting effects of psilocybin suggest that it may be a promising treatment option.
It is important to note that taking psychedelics does not work for everyone, and there are serious risks associated with self-medicating without the supervision of trained mental health experts. However, with ongoing research and a better understanding of how psilocybin affects the brain, it may become a valuable tool in the treatment of depression, anxiety, and other mental health disorders.

Activating serotonin receptors
Psilocybin, the psychedelic compound in mushrooms, has been found to have therapeutic effects in relieving mental health symptoms such as depression, anxiety, and post-traumatic stress disorder (PTSD). It is also being studied for its potential in treating other brain and mental health disorders.
Psilocybin activates serotonin receptors on brain cells, reducing the energy required for the brain to switch between different activity states. This activation of serotonin 2a receptors is believed to be the primary mechanism through which psilocybin and LSD produce their effects. By mapping the distribution of these receptors in the brain using positron emission tomography (PET) studies, researchers found that these psychedelic drugs lowered or "flattened" the normal energy barriers, allowing the brain to transition from one state to another more easily.
In a study conducted by Dr. Joshua Siegel at Washington University in St. Louis, functional magnetic resonance imaging (fMRI) was used to track changes in brain activity related to psilocybin use. The results revealed that psilocybin caused significant disruptions in functional connectivity (FC) throughout the brain, including the cerebral cortex, thalamus, hippocampus, and cerebellum. These disruptions were more than three times greater than those caused by a control compound, methylphenidate.
The impact of psilocybin on FC has also been observed in the cortex and subcortex, with some changes persisting for weeks after ingestion. This disruption in FC may be related to the therapeutic effects of psilocybin, as it temporarily alters the brain's ability to perceive time, space, and the self. The longer-term consequence of this desynchronization may be a more flexible brain that is potentially more capable of achieving a healthier state.

Therapeutic effects
Psilocybin, the psychedelic substance in mushrooms, has been the subject of numerous studies to determine its effects on the brain and its potential therapeutic benefits.
One of the key findings from these studies is that psilocybin disrupts functional connectivity (FC) in the brain, causing a desynchronization of neural networks. This desynchronization leads to a temporary loss of individuality and a distorted sense of self, space, and time. While this can result in a psychedelic experience, it may also have therapeutic benefits for mental health disorders.
The therapeutic effects of psilocybin have been observed in the treatment of depression, anxiety, post-traumatic stress disorder (PTSD), and cluster headaches. In some cases, a single dose of psilocybin has led to long-lasting improvements, even after the acute effects of the drug have worn off. This suggests that psilocybin may induce lasting changes in the brain that contribute to sustained relief from mental health symptoms.
Microdosing is another approach that has gained attention for its potential therapeutic benefits. This involves taking small amounts of psilocybin regularly to maintain brain health and enhance creativity. While the effects of microdosing are still being studied, self-reported surveys suggest that individuals who engage in this practice experience positive outcomes.
It is important to note that the use of psilocybin carries risks and should be approached with caution. While it has the potential to provide therapeutic benefits, it can also lead to negative or scary experiences. Therefore, it is crucial to have trained experts supervise and guide individuals through the experience to ensure their safety and well-being.
