Magic mushrooms have been shown to have a profound effect on the nervous system, particularly the brain. The psychoactive ingredient in magic mushrooms, psilocybin, has been linked to several potential health benefits, including the relief of anxiety and depression. Psilocybin affects the brain's prefrontal cortex, which regulates abstract thinking, thought analysis, mood, and perception. It also affects the brain's serotonin levels, leading to hallucinations and distorted perceptions of reality. While the effects of magic mushrooms can be positive, they can also cause extreme paranoia and discomfort. Scientists are still working to understand the full range of effects that magic mushrooms have on the nervous system.

What You'll Learn
Hallucinations and distorted perceptions of reality
Hallucinogenic drugs like magic mushrooms can induce hallucinations and distort perceptions of reality. Magic mushrooms contain psilocybin, a psychoactive ingredient that affects the brain's prefrontal cortex, which regulates abstract thinking, thought analysis, mood, and perception.
When ingested, psilocybin is broken down into psilocin, which prevents the reuptake of serotonin, a neurotransmitter that influences mood, social behaviour, memory, and sexual desire. Psilocin has a similar chemical structure to serotonin, allowing it to bind to and stimulate brain receptors. This amplified stimulation leads to hallucinations, where individuals perceive and experience things without any external stimulus.
Under the influence of psilocybin, individuals may experience synesthesia, a subconscious pairing of senses, such as seeing sounds or hearing colours. This effect has been attributed to enhanced communication across brain networks, with researchers observing new and stronger activity in multiple brain regions that rarely engage in such "cross-talk."
The impact of psilocybin on the brain can lead to intense hallucinations and distorted reality. Individuals may have difficulty distinguishing reality from fantasy, as the drug inhibits normal brain activity and promotes the formation of new, biologically stable connections. These neurological changes can be long-lasting, with some studies reporting personality shifts towards openness to creative arts and increased happiness even 14 months after psilocybin exposure.
While magic mushrooms are known for their hallucinogenic effects, they also hold potential therapeutic benefits. Several studies suggest that psilocybin may help alleviate severe anxiety and depression, particularly in cancer patients. The loosening and creation of new brain connections may contribute to the reported relief from depressive thinking and intensified emotions. However, it is important to note that the use of magic mushrooms also carries risks, and further scientific research is needed to fully understand their complex effects on the nervous system.

Feelings of relaxation and spiritual experiences
Magic mushrooms have been linked to feelings of relaxation and spiritual experiences. The psychoactive ingredient in magic mushrooms, psilocybin, has been associated with several potential health benefits, including the ability to relieve anxiety and depression. According to the National Institute on Drug Abuse, magic mushrooms can induce feelings of relaxation similar to the effects of low doses of marijuana.
Psilocybin affects the brain's prefrontal cortex, which regulates abstract thinking, thought analysis, mood, and perception. This can lead to hallucinations, with users reporting experiences such as seeing sounds or hearing colours. The drug also inhibits normal brain activity, leading to temporary rearrangements in the brain's connections and the creation of new, biologically stable connections. This may explain why people under the influence of magic mushrooms may have difficulty distinguishing reality from fantasy.
The emotional and spiritual effects of magic mushrooms can be profound. Nick Fernandez, a participant in a 2014 New York University study, described his experience as an emotional journey that helped him see "a force greater than [himself]." He reported feeling that his "anxieties, defenses, and insecurities weren't something to worry about." Many other participants in the study had similar experiences, which psychotherapist Jeffrey Guss described as "part of the healing process."
The neurological changes induced by psilocybin can be long-lasting. Research has shown that a single dose of psilocybin can lead to reduced symptoms of depression and anxiety months after the experience. Additionally, prior studies have found that the effects of psilocybin can last over a year, resulting in a happier mood and an increased openness to creative arts.

Intense emotions and changes in mood
Psilocybin, the active ingredient in magic mushrooms, has been shown to have a significant impact on intense emotions and changes in mood. The effects of psilocybin are generally similar to those of LSD, including an altered perception of time and space, and intense mood changes.
Psilocybin works by binding to and activating serotonin receptors in parts of the brain such as the prefrontal cortex and amygdala, which regulate mood, cognition, and perception. Hallucinogens also work in other regions of the brain that regulate arousal and panic responses. The effects of psilocybin on the brain can be seen through functional magnetic resonance imaging (fMRI) studies, which have found that it reduces amygdala activity and connectivity when viewing negative emotional facial expressions. This reduction in amygdala activity is associated with a decrease in negative affect and an increase in positive affect.
The impact of psilocybin on emotions and brain function can last up to one month after a single high dose. This includes a reduction in negative affect and amygdala response to negative stimuli, as well as an increase in positive affect and dorsal lateral prefrontal and medial orbitofrontal cortex responses to emotionally conflicting stimuli.
In addition to the acute effects of psilocybin, there is also evidence of long-term changes in mood and emotional processing. For example, some people who take psilocybin may experience persistent alterations in their visual perception, such as flashbacks or traumatic recall of intensely upsetting experiences. These effects can last from weeks to years after using the hallucinogen and are known as hallucinogen-persisting perception disorder, which is rare.
The impact of psilocybin on intense emotions and mood changes has been explored in the context of therapeutic settings, particularly for the treatment of mood and substance use disorders. Small clinical trials have shown that one or two doses of psilocybin, when administered therapeutically, can lead to dramatic and long-lasting changes in people with treatment-resistant major depressive disorder. This has led to the US Food and Drug Administration describing psilocybin as a breakthrough medicine. However, it is important to note that not all hallucinogenic experiences are positive, and there is a risk of ""bad trips"" that can include intense anxiety, fear, paranoia, and loss of boundaries.

Altered brain activity and connectivity
The active chemical in magic mushrooms, psilocybin, is known to affect the brain's prefrontal cortex, which regulates abstract thinking, thought analysis, and plays a role in mood and perception. This effect on the prefrontal cortex can lead to hallucinations, with users reporting experiences such as seeing sounds or hearing colours.
A 2014 study found that psilocybin impacts communication across brain networks, resulting in new and stronger activity across multiple regions of the brain that typically do not engage in such "cross-talk". This altered brain connectivity may explain the phenomenon of synesthesia, where individuals associate colours with numbers, for example.
The impact of psilocybin on the brain's neural highways and the neurotransmitter serotonin is also noteworthy. Psilocybin prevents the reuptake of serotonin, which affects mood, social behaviour, memory, and sexual desire. The structural similarity between psilocin (the byproduct of psilocybin breakdown) and serotonin enables psilocin to bind to and stimulate brain receptors, leading to amplified stimulation and hallucinations.
Furthermore, magic mushrooms may help loosen overly strong connections in the brain's "sense-of-self" region, which is implicated in depressive thinking. This effect could provide relief from depression and anxiety, as suggested by clinical trials. The rearrangement of brain connections and the formation of new, stable connections may contribute to the reported sense of oneness with the world and transformative spiritual experiences.

Potential treatment for anxiety and depression
Several studies have explored the potential of using psilocybin, the psychoactive ingredient in magic mushrooms, as a treatment for anxiety and depression.
A 2014 New York University study investigated the effects of psilocybin on cancer patients with severe anxiety. Participants received either a dose of psilocybin in pill form or a placebo. One participant, Nick Fernandez, described his experience as an emotional journey that helped him realise that his "anxieties, defenses, and insecurities weren't something to worry about". NYU psychotherapist Jeffrey Guss noted that many participants had similar experiences, which he considered part of the healing process. However, it is important to note that some participants in the NYU study also reported experiencing intense anxiety and discomfort during their trip.
Another study by Johns Hopkins University researchers examined the effects of psilocybin on patients dealing with depression and distress related to facing the end of life. Six months after receiving a single dose of psilocybin, 80% of participants showed significant decreases in symptoms of depression and anxiety, as measured by a gold-standard psychiatric evaluation.
A 2016 study found that mushrooms helped lift depression in patients with treatment-resistant depression, with over half of the participants continuing to show reduced symptoms three months later.
The potential therapeutic effects of psilocybin are believed to be related to its impact on serotonin, a neurotransmitter that affects mood, social behaviour, memory, and sexual desire. Psilocybin prevents the reuptake of serotonin and binds to its receptors in the brain, altering mood and potentially providing relief from depressive thinking. Additionally, psilocybin has been found to increase communication across different regions of the brain, leading to new, stable connections that may contribute to the reported benefits.
