Magic mushrooms are hallucinogenic drugs that alter the chemical composition of brain cells, causing a profound shift in perception and sensation. Psilocybin, the active compound in magic mushrooms, has been studied for its potential therapeutic effects, particularly in treating depression. However, the complex pharmacology of psilocybin and its impact on the human brain, specifically its ability to disrupt functional connectivity, has raised concerns about its safety. The addition of unknown substances by dealers and the risk of consuming poisonous mushrooms further contribute to the potential dangers associated with magic mushroom consumption. While the number of brain cells killed by mushrooms is not definitively known, the alteration of brain cell chemistry and the resulting changes in perception and sensation highlight the potential risks of magic mushroom usage.

Magic mushrooms alter brain cell chemical composition
Magic mushrooms, or "shrooms", are hallucinogenic drugs that alter the chemical composition of brain cells. They contain the psychedelic compound psilocybin, which has been studied for its potential therapeutic effects, particularly in treating depression. Psilocybin induces a state of ego dissolution, profoundly altering human awareness, perception, and sensation by disrupting the brain's default mode network.
Psilocybin's effects on the brain are extensive and complex. It acutely causes distortions in space-time perception and the sense of self, resulting in a mystical experience. This is achieved through the desynchronization of brain networks, particularly in the cortex and hippocampus. Brain imaging studies have revealed that psilocybin massively disrupts functional connectivity (FC) in these regions, with changes more than three times greater than those caused by methylphenidate.
The default mode network, which is usually most active when the brain is at rest, governs our sense of space, time, and self. By disrupting this network, psilocybin induces a state of disconnection from reality, altering the perception of the world and one's place in it. This can lead to a sense of oneness with the universe and a loss of the boundaries of the self, resulting in a profound mystical experience.
In addition to its effects on perception and sensation, psilocybin also has the potential to provide therapeutic benefits. Clinical trials have shown that a single high dose of psilocybin can provide immediate and sustained relief from symptoms of depression and addiction. This is thought to be due to the increased neuroplasticity and connectivity induced by psilocybin, which may help to rewire the brain and form new neural connections.
However, it is important to note that magic mushrooms can also be dangerous. Dealers often add other substances to enhance their potency, which can be harmful to the delicate brain cells. Additionally, identifying mushrooms in the wild can be challenging, and consuming the wrong type of mushroom can lead to severe health risks, including kidney damage. While the psychedelic experience may be sought by some, it is crucial to approach these substances with caution and be aware of their potential risks and side effects.

Psilocybin causes brain network desynchronization
Psilocybin, the active ingredient in so-called "magic mushrooms", has been found to desynchronize brain networks. This desynchronization is believed to be caused by the activation of 5-HT2A serotonin receptors, which disrupts the normal co-activation of neurons, resulting in a more random pattern of brain activity. This disruption of neural activity has been linked to the cognitive and perceptual changes associated with psilocybin, including distortions of space-time perception and ego dissolution.
Precision functional mapping (PFM) studies have revealed that psilocybin produces significant changes in brain network structure, including a decrease in functional connectivity between the anterior hippocampus and cortex. These changes are believed to be responsible for the therapeutic effects of psilocybin, particularly in the treatment of depression and addiction. Clinical trials have shown that a single high dose of psilocybin can provide immediate and sustained symptom relief.
The acute effects of psilocybin on the brain are consistent with distortions of space-time and the self. This is supported by the observation that psilocybin-induced network changes are reduced when individuals perform perceptual tasks, suggesting a neurobiological basis for grounding or connecting with physical reality during psychedelic therapy. By directing attention externally, individuals can alleviate intense or distressing thoughts and emotions that may arise during the psychedelic experience.
The desynchronization of brain networks induced by psilocybin is not permanent and has been shown to normalize after 6 months. This suggests that the brain is able to recover from the acute effects of psilocybin and return to its baseline state. However, the long-term effects of psilocybin use, particularly with repeated or frequent use, are still not fully understood and require further study.
While psilocybin can induce desynchronization across the brain, the default mode network (DMN) is particularly affected. The DMN is connected to the anterior hippocampus and is thought to be responsible for our sense of self. The disruption of hippocampal-DMN connectivity may be a key mechanism underlying the therapeutic effects of psilocybin, particularly in the treatment of depression and other psychiatric illnesses.

Hallucinogens and serotonin receptor agonism
Hallucinogens like mushrooms alter the chemical composition of the brain's cells, resulting in a profound shift in perception and sensation. This shift in perception is commonly referred to as a "trip" and can last for several hours. While the effects of a "trip" may fade, the drugs can leave a trail of chemical changes in their wake, which can be damaging and dangerous.
Mushrooms, or more specifically, the hallucinogenic ingredient psilocybin, are known to induce widespread brain network changes. These changes are greater than those induced by other state changes, such as treatment with methylphenidate. Psilocybin decreases neuronal activity in key brain regions and decreases brain "connectivity." It also induces plasticity in the hippocampus and cortex, which is believed to be necessary for its rapid antidepressant-like effects.
The psychedelic effects of hallucinogens are primarily driven by their agonist activity at the serotonin 2A (5-HT2A) receptor. Serotonergic psychedelics, including psilocybin, LSD, and mescaline, have a high affinity for serotonin (5-HT) receptors. They act as partial agonists at 5-HT2A and other 5-HT2 receptors in the central nervous system.
The dual effects of psychedelics on 5-HT2AR (excitatory) and 5-HT1AR (inhibitory) signaling may contribute to their unique effects on neuronal excitability and synaptic remodeling, which could underlie their antidepressant and anxiolytic properties. Classical hallucinogens also appear to be devoid of activity in 5-HT2A knockout mice, further supporting the importance of this receptor in their mechanism of action.
Overall, hallucinogens and their interaction with serotonin receptors, particularly 5-HT2A, play a critical role in mediating their effects on the human brain.

Brain activity patterns disturbed by psilocybin
Hallucinogenic drugs like magic mushrooms, which contain psilocybin, alter the chemical composition of the brain's cells. When active, they produce a profound shift in perception and sensation, causing a person to experience a "trip". These drugs can leave behind a swath of chemical changes, some of which may be considered damaging or dangerous.
Psilocybin has been found to massively disrupt functional connectivity in the cortex and subcortex, with some changes persisting for weeks. It induces a persistent decrease in functional connectivity between the anterior hippocampus and cortex, lasting for weeks but normalizing after 6 months. This suppression of hippocampal-DMN connectivity is a candidate neuroanatomical and mechanistic correlate for psilocybin’s pro-plasticity and anti-depressant effects.
Psilocybin also desynchronizes brain networks, causing a profound and widespread—yet not permanent—change to the brain’s functional networks. It specifically affects the default mode network, an interconnected set of brain areas that are simultaneously active when the brain is not working on anything in particular. After falling out of sync, the network re-established itself when the acute effects of the drug wore off, but small differences from pre-psilocybin scans persisted for weeks.
Psilocybin's effects on brain activity patterns have been visualized through heat maps, which show profound disturbances during an individual’s experience after taking the drug. The relatively stable patterns before and after the dose are temporarily scrambled during the "trip". These findings provide a neurobiological explanation for the drug’s mind-bending effects and lay the groundwork for the development of psilocybin-based therapies for mental illnesses.
In summary, psilocybin significantly disturbs brain activity patterns, causing widespread desynchronization and decreased functional connectivity in the brain. These effects are particularly pronounced in the cortex and subcortex, as well as in the default mode network. While most brain activity returns to normal within days to weeks, small differences in brain scans have been observed to persist even after 6 months. These findings have important implications for understanding the therapeutic potential of psilocybin in treating mental illnesses.

Neurotoxicity and brain cell death
Hallucinogenic drugs like mushrooms alter the chemical composition of brain cells. When active, they produce a profound shift in perception and sensation, causing a person to experience a "high" or "trip" that can last for hours. While users may feel that they have returned to a familiar reality after a trip, these drugs can leave behind a trail of chemical changes.
Mushrooms contain psilocybin, a psychedelic compound that acutely causes distortions of space-time perception and ego dissolution. Psilocybin massively disrupts functional connectivity in the cortex and subcortex, with some changes persisting for weeks. It also decreases brain "connectivity" as measured by pharmaco-physiological interaction. A single dose of psilocybin has been shown to produce rapid and persistent therapeutic effects in human clinical trials. It induces neuroplasticity in the cortex and hippocampus, which is necessary for rapid antidepressant-like effects in animal models.
Psilocybin-induced network changes suggest a neurobiological basis for grounding and connecting with physical reality during psychedelic therapy. The acute brain effects of psilocybin are consistent with distortions of space-time and the self. It induces a persistent decrease in functional connectivity between the anterior hippocampus and cortex, lasting for weeks but normalizing after 6 months. These changes represent a neuroanatomical and mechanistic correlate for psilocybin's pro-plasticity and anti-depressant effects.
Psychedelic drugs can reliably induce powerful changes in the perception of self, time, and space via agonism of the serotonin 2A receptor (5-HT2A receptor). In clinical trials, a single high dose of psilocybin has demonstrated immediate and sustained symptom relief in depression, addiction, and other mental health conditions. However, it is important to note that the addition of other substances by dealers or the consumption of wild mushrooms without proper identification can significantly increase the risk of damage to brain cells and other serious health risks.
