Psychedelic mushrooms, often referred to as magic mushrooms, have been consumed by humans for over 9,000 years. Even today, these naturally occurring fungi are popular as recreational drugs due to their ability to induce hallucinations. But what exactly happens in the brain when you consume them?
The primary psychoactive compound in these mushrooms is psilocybin. Once ingested, the body converts psilocybin into psilocin, which then travels to the brain. Psilocin interferes with the re-uptake of serotonin, a key neurotransmitter, thereby enhancing its activity. Moreover, because psilocin’s chemical structure closely resembles that of serotonin, it can bind to and activate serotonin receptors in the brain. This heightened stimulation leads to hallucinations, where individuals perceive things that aren’t actually present. These hallucinations can be visual, auditory, or even mystical and insightful experiences.
While many users find the experience enjoyable, some report unpleasant episodes. The effects typically last between 3 to 8 hours, although they can feel much longer due to the drug’s impact on the perception of time. Researchers suggest that psilocybin may temporarily reorganize the brain by inhibiting normal activity and forming new, stable connections. This reorganization makes it challenging to distinguish reality from fantasy and intensifies thought processes, making tasks like planning and self-reflection difficult.
Increased activity in the hippocampus and anterior cingulate cortex, areas associated with dreaming, has been observed. Emotional regions of the brain are also activated, potentially leading to a sense of expanded consciousness. This temporary alteration of brain pathways makes thinking outside the box feel natural.
In a significant study involving 36 college-educated participants who were administered psilocybin in a controlled setting, one-third described the experience as the most spiritually significant moment of their lives, while two-thirds ranked it among their top five. Two months post-experience, 79% of participants reported improved well-being and satisfaction, a sentiment echoed by their friends and family.
However, not all experiences are positive. About 22% of participants in clinical trials experienced fear and paranoia, often manifesting as terrifying and uncontrollable hallucinations.
Despite the unknowns surrounding magic mushrooms, they are not considered clinically addictive and pose minimal toxicity to other organ systems. A UK study even found that they cause the least harm to individuals and others compared to other recreational drugs. Scientists advocate for changes in laws to facilitate more comprehensive clinical testing, aiming to fully understand both the positive and negative effects of this intriguing fungus on the brain.

Research and create a detailed diagram tracing the journey of psilocybin from ingestion to its effects on the brain. Highlight the conversion to psilocin and its interaction with serotonin receptors. Present your findings in a group discussion to deepen your understanding of the biochemical processes involved.
Analyze a case study of a controlled psilocybin experience. Focus on the psychological and physiological effects observed. Discuss in small groups how these effects align with the information provided in the article, and consider the implications for mental health treatment.
Participate in a debate on the legalization of psilocybin for research purposes. Prepare arguments for and against, considering the potential benefits and risks. This will help you critically evaluate the current legal landscape and its impact on scientific progress.
Engage in a creative writing or art project that reflects the altered states of consciousness described in the article. Use this exercise to explore the subjective experiences of psilocybin users and how these might influence perception and creativity.
Develop a research proposal for a study on the effects of psilocybin on brain function and mental health. Outline your hypothesis, methodology, and potential implications. This activity will enhance your research skills and understanding of experimental design.
Psychedelic or magic mushrooms have been ingested by humans for over 9,000 years. Even today, this naturally grown fungus is commonly used as a recreational drug, causing hallucinations. But how exactly does it work?
The main psychoactive ingredient in mushrooms is called psilocybin. When ingested, the body breaks it down into the active drug psilocin, which makes its way to the brain. Here, it begins to prevent the re-uptake of the neurotransmitter serotonin, increasing its activity. Additionally, psilocin has a similar chemical structure to serotonin, allowing it to bind to and stimulate receptors in the brain. This amplified stimulation causes individuals to perceive and experience things without any real stimulus, also known as hallucinations. These can vary from visual to auditory sensations or mystical and insightful feelings.
While the experience can be quite enjoyable, some users have reported unpleasant episodes. These feelings generally last between 3 to 8 hours but can feel much longer as the drug alters the sense of time. Scientists have suggested that the brain may temporarily rearrange itself by inhibiting normal brain activity and creating new biologically stable brain connections. This ultimately makes it harder to determine reality from fantasy and amplifies the intensity of thought, making planning ahead and self-conscious thinking almost impossible.
Activation in the hippocampus and anterior cingulate cortex, which are associated with dreaming, has also been observed. Specific emotional regions of the brain are chemically activated, which can lead to a sense of expanding consciousness. Because the drug temporarily alters pathways in the brain, thinking outside the box becomes extremely natural.
In a notable study, 36 college-educated participants were given psilocybin and observed in a laboratory. One-third reported the experience as the single most spiritually significant moment in their lives, with two-thirds placing it in their top five. Two months after taking the drug, 79% of participants reported increased well-being and satisfaction. Friends and family were also interviewed and agreed with these claims.
However, it’s not all positive; 22% of clinically tested individuals experienced fear and paranoia at certain points during their trip, which typically manifested as terrifying and uncontrollable hallucinations.
Though much is still unknown about magic mushrooms, they are not considered clinically addictive and cause little toxicity to other organ systems. In fact, a UK study found that they cause the least amount of damage to individuals and others when compared to other recreational drugs. Ultimately, scientists believe that laws need to change around clinical testing of the drug so advanced research can be conducted to fully understand both the positive and negative effects that this magic fungus has on our brain.
