Magic mushrooms, also known as psilocybin mushrooms, are hallucinogenic and have been used in various cultures and locations across the world, potentially as far back as 8,000 years ago. Psilocybin is a naturally occurring tryptamine alkaloid found in more than 200 species of mushrooms. When ingested, psilocybin is metabolized into psilocin, which activates serotonin receptors in the brain. Psilocybin also affects the brain's prefrontal cortex, which regulates mood, cognition, and perception. Recent studies have shown that psilocybin can decrease brain connectivity and help reorganize brain activity, providing potential therapeutic benefits for treating depression and anxiety.

Psilocybin is a serotonergic psychedelic that acts as a prodrug of psilocin
Psilocybin, also known as 4-phosphoryloxy-N,N-dimethyltryptamine (4-PO-DMT), is a naturally occurring tryptamine alkaloid and investigational drug found in more than 200 species of mushrooms. It has hallucinogenic and serotonergic effects. The effects of psilocybin include euphoria, changes in perception, a distorted sense of time, and perceived spiritual experiences. It can also cause adverse reactions such as nausea and panic attacks.
Psilocybin is a prodrug of psilocin, meaning that psilocybin itself is biologically inactive but is converted by the body into psilocin, which is the active form of the drug. Psilocin is chemically related to the neurotransmitter serotonin and acts as a non-selective agonist of the serotonin receptors. It has a high affinity for most serotonin receptors, except for the serotonin 5-HT3 receptor. Psilocybin's psychedelic effects are mediated by agonism of the serotonin 5-HT2A receptor.
The psilocybin present in certain species of mushrooms can be ingested in several ways, including consuming fresh or dried mushrooms, preparing herbal tea, or combining with other foods to mask the bitter taste. Microdosing of psilocybin involves the use of sub-threshold doses of less than 2.5 mg. Psilocybin's effects can be subjectively perceived at doses as low as 3 mg per 70 kg body weight.
Psilocybin has been found to have potential therapeutic benefits in the treatment of psychiatric disorders such as depression and anxiety. It has been shown to promote neuroplasticity in the brain and produce psychoplastogenic effects in animals, including dendritogenesis, spinogenesis, and synaptogenesis. Researchers from Johns Hopkins University and New York University have found that a single dose of psilocybin could be a powerful tool for treating depression and anxiety.

Psilocin is a close analogue of the monoamine neurotransmitter serotonin
Psilocybin, the main active agent in "magic mushrooms", is an indole hallucinogen. It is a prodrug of psilocin, which is the pharmacologically active metabolite of psilocybin. In other words, psilocybin is biologically inactive until it is converted into psilocin by the body.
Psilocin's affinity for the serotonin 5-HT2A receptor is particularly notable, with levels 15 times higher in humans than in rats. Activation of the 5-HT2A receptor is specifically responsible for the hallucinogenic effects of psilocin and other serotonergic psychedelics. This activation leads to increased cortical activity and plays a role in the subjective mind-altering effects of psilocin, which can include visual and auditory hallucinations, intensified hearing, and incoordination.
The effects of psilocybin-containing mushrooms are thus believed to be primarily mediated through their influence on serotonin receptors, particularly the 5-HT2A receptor. This understanding of how psilocybin and psilocin interact with neurotransmitters has led to ongoing clinical trials investigating their potential therapeutic benefits in treating various mental health conditions.

Psilocybin activates serotonin receptors in parts of the brain that affect mood, cognition, and perception
Psilocybin, also known as 4-phosphoryloxy-N,N-dimethyltryptamine (4-PO-DMT), is a naturally occurring tryptamine alkaloid with hallucinogenic and serotonergic effects. It is the active compound in psilocybin-containing mushrooms, which are commonly referred to as "magic mushrooms" or "shrooms".
Psilocybin interacts with serotonin receptors in the brain, specifically acting as a non-selective agonist of these receptors. Serotonin receptors play a crucial role in regulating mood, emotions, and other cognitive functions. By activating these receptors, psilocybin increases serotonin transmission, leading to altered states of consciousness and changes in perception, mood, and cognition.
The prefrontal cortex and the amygdala are two key areas of the brain affected by psilocybin's interaction with serotonin receptors. The prefrontal cortex is responsible for executive functions such as decision-making, planning, and working memory, and it also plays a role in regulating mood. The amygdala, on the other hand, is involved in processing and regulating emotional responses, particularly those related to fear and anxiety.
Research has shown that psilocybin can produce therapeutic effects, such as treating depression, anxiety, and distress related to end-of-life situations. It has also been found to have anti-inflammatory properties and influence the gut-brain axis. However, it's important to note that psilocybin can also cause adverse reactions, such as nausea, panic attacks, and, in rare cases, hallucinogen-persisting perception disorder.

Psilocybin may cause visual or auditory hallucinations
Psilocybin, a naturally occurring psychedelic found in certain types of mushrooms, has hallucinogenic and serotonergic effects. It is a prodrug of psilocin, which is chemically related to the neurotransmitter serotonin. Serotonin is a monoamine neurotransmitter that is a derivative of the amino acid tryptophan.
Psilocybin works by binding to and activating serotonin receptors in parts of the brain, such as the prefrontal cortex and amygdala, which affect mood, cognition, and perception. By acting on these neural highways in the brain, psilocybin can cause visual or auditory hallucinations, distort how objects and people are perceived, and alter one's sense of reality.
The effects of psilocybin vary widely and depend on set and setting, as well as one's expectations. Some people may experience disturbing hallucinations, anxiety, paranoia, and panic after taking the drug. In rare cases, taking a huge amount of mushrooms can lead to severe side effects, including death. However, psilocybin is not considered addictive, and there are no physical symptoms after stopping use.
Psilocybin mushrooms can be ingested in several ways, including consuming fresh or dried mushrooms, preparing herbal tea, or combining with other foods to mask the bitter taste. The effects typically begin within 30 to 45 minutes and can last up to 6 hours. Low doses are typically considered to be 5 to 10 mg, while high or ego-dissolution doses can range from 30 to 40 mg.
While the risks associated with psilocybin use are generally mild to moderate, it is important to note that hallucinogenic drugs can cause unpredictable and potentially dangerous behavior. Additionally, dried hallucinogenic mushrooms may contain other substances that affect their safety profile, and there is a risk of accidentally consuming poisonous mushrooms.

Magic mushrooms could change the way brain networks function by affecting neuron firing and neurotransmitter dynamics
Magic mushrooms, or mushrooms containing psilocybin, have been used by humans for as long as 8,000 years. They are often ingested for their hallucinogenic effects, which can range from euphoria to hallucinations. The effects of psilocybin are thought to be produced by acting on neural highways in the brain that use the neurotransmitter serotonin.
Psilocybin is a naturally occurring tryptamine alkaloid found in more than 200 species of mushrooms. It is structurally related to serotonin, a monoamine neurotransmitter that is a derivative of the amino acid tryptophan. Psilocybin is metabolically inert and is converted by the body into psilocin, its active form, which is a close analogue of serotonin.
Psilocybin and psilocin activate serotonin receptors in the brain, including the 5-HT2A receptor, which is believed to be responsible for their psychedelic effects. By activating these receptors, psilocybin and psilocin can affect the prefrontal cortex and other regions of the brain that regulate mood, cognition, perception, arousal, and panic responses.
Research has shown that psilocybin can decrease brain "connectivity" and diminish neuronal activity in certain regions of the brain. This decrease in connectivity may be related to the destabilization of brain networks, leading to the formation of new networks. This suggests that magic mushrooms can change the way brain networks function by affecting neuron firing and neurotransmitter dynamics.
The unique effects of magic mushrooms on brain networks have sparked interest in their potential therapeutic applications. Clinical trials have shown promising results in using psilocybin to treat depression, anxiety, and distress related to end-of-life situations. Further research is needed to fully understand the neurobiological effects of psilocybin and its potential in treating neuropsychiatric disorders.
