Magic mushrooms, or more specifically, the psilocybin found in them, may be able to 'reset' the brain. Psilocybin is a psychedelic compound that occurs naturally in magic mushrooms and has been found to improve mood in people with treatment-resistant depression. A single dose of psilocybin has been found to reduce negative affect and amygdala response to negative affective stimuli, while increasing positive affect and dorsal lateral prefrontal and medial orbitofrontal cortex responses to emotionally conflicting stimuli. Patients who have taken psilocybin have reported feeling reset, reborn, or rebooted, and brain imaging studies have shown that psilocybin may reset the activity of key brain circuits known to play a role in depression.

Magic mushrooms may reset the brains of depressed patients
Magic mushrooms may be the answer to resetting the brains of depressed patients and alleviating their mental health issues. Psilocybin, the psychoactive compound that naturally occurs in magic mushrooms, has been found to improve the mood of people with treatment-resistant depression. A single dose of psilocybin, combined with talk therapy, can improve mood and alleviate poor mental health.
A study by researchers from Imperial College London found that patients taking psilocybin to treat depression showed reduced symptoms weeks after treatment, following a "reset" of their brain activity. The researchers treated a small number of patients with depression in whom conventional treatment had failed. They observed changes in brain activity that were associated with marked and lasting reductions in depressive symptoms. The patients also self-reported benefits lasting up to five weeks after treatment.
Dr Robin Carhart-Harris, Head of Psychedelic Research at Imperial, who led the study, said, "We have shown for the first time clear changes in brain activity in depressed people treated with psilocybin after failing to respond to conventional treatments. Several of our patients described feeling 'reset' after the treatment and often used computer analogies. For example, one said he felt like his brain had been 'defragged' like a computer hard drive, and another said he felt 'rebooted'".
Psilocybin appears to reset the activity of key brain circuits known to play a role in depression. It causes lasting changes to the communication pathways that connect brain regions. It also temporarily resets entire networks of neurons in the brain that are responsible for controlling a person's sense of time and self.
While the initial findings are encouraging, the research is still in its early stages. The authors of the study caution that patients with depression should not attempt to self-medicate, as the team provided a special therapeutic context for the drug experience, and things may go awry if the extensive psychological component of the treatment is neglected. Further studies with more robust designs are needed before psilocybin can be accepted as a standard treatment for depression.

Psilocybin may help treat depression
Psilocybin, the hallucinogenic compound found in magic mushrooms, has been found to have a positive impact on people with treatment-resistant depression. A single dose of psilocybin, combined with talk therapy, has been found to alleviate poor mental health almost immediately.
Psilocybin resets neural networks by causing lasting changes to the communication pathways that connect brain regions. It activates the 5-HT2A receptor, a serotonin receptor widely distributed in the central nervous system. The activation of these downstream signalling pathways can influence gene expression, which can then go on to influence synaptic plasticity and brain neurochemistry. These effects are often long-term.
Several patients have described feeling "reset" after the treatment. One said he felt like his brain had been "defragged" like a computer hard drive, and another said he felt "rebooted".
Dr Robin Carhart-Harris, Head of Psychedelic Research at Imperial, who led the study, said: "We have shown for the first time clear changes in brain activity in depressed people treated with psilocybin after failing to respond to conventional treatments."
Prof Mitul Mehta, from the Institute of Psychiatry at King's College London, said: "What is impressive about these preliminary findings is that brain changes occurred in the networks we know are involved in depression, after just a single dose of psilocybin. This provides a clear rationale to now look at the longer-term mechanisms in controlled studies."

Brain activity changes after taking psilocybin
Psilocybin, the hallucinogenic compound found in magic mushrooms, has been found to alter brain activity. A single dose of psilocybin has been found to improve mood in people with treatment-resistant depression within three weeks.
A study by Imperial College London found that patients taking psilocybin to treat depression showed reduced symptoms weeks after treatment, indicating a 'reset' of their brain activity. The researchers described patient-reported benefits lasting up to five weeks after treatment, and they believe that psilocybin may effectively reset the activity of key brain circuits known to play a role in depression.
Another study that repeatedly imaged the brains of volunteers before, during, and after they took a high dose of psilocybin found that psilocybin temporarily resets entire networks of neurons in the brain that are responsible for controlling a person's sense of time and self.
Psilocybin is a classic psychedelic compound that may be effective in treating mood and substance use disorders. Acute effects of psilocybin include reduced negative mood, increased positive mood, and reduced amygdala response to negative affective stimuli. One week after taking psilocybin, negative affect and amygdala response to facial affect stimuli were reduced, while positive affect and dorsal lateral prefrontal and medial orbitofrontal cortex responses to emotionally conflicting stimuli were increased.
Psychedelics like psilocybin activate the 5-HT2A receptor, a serotonin receptor widely distributed in the central nervous system and especially dense in brain regions essential for learning and cognition, such as the pre-frontal cortex. Activation of the 5-HT2A receptor can influence gene expression, which can then impact synaptic plasticity and brain neurochemistry, resulting in long-term changes that may contribute to the therapeutic benefits of psilocybin.

Psilocybin may alter the brain's sense of time and self
Psilocybin, the hallucinogenic compound found in magic mushrooms, has been found to alter the brain's sense of time and self. A study that repeatedly imaged the brains of volunteers before, during, and after they took a large dose of psilocybin found that the drug temporarily resets entire networks of neurons in the brain responsible for controlling a person's sense of time and self.
The effects of psilocybin on the brain are mediated by effector pathways induced by the activation of the 5-HT2A receptor, a serotonin receptor. This receptor is widely distributed in the central nervous system and is especially dense in brain regions essential for learning and cognition, such as the pre-frontal cortex. The activation of these downstream signalling pathways can influence gene expression, with induced long-term changes likely underpinning the therapeutic efficacy of a single administration of psychedelics to achieve lasting effects.
Psilocybin has been found to reduce negative mood, increase positive mood, and reduce amygdala response to negative affective stimuli. Studies suggest that psilocybin may have efficacy for the treatment of mood and substance use disorders, as well as depression and anxiety. One study found that one week after taking psilocybin, participants showed reduced negative affect and amygdala response to facial affect stimuli, while positive affect and dorsal lateral prefrontal and medial orbitofrontal cortex responses to emotionally conflicting stimuli were increased.
The effects of psilocybin on the brain's sense of time and self are still being studied, and more research is needed to fully understand the potential therapeutic benefits of this compound. However, the current findings suggest that psilocybin may have the potential to treat a range of mental health conditions and improve overall well-being.

The effects of psilocybin on the brain may be long-lasting
Psilocybin, the hallucinogenic compound found in magic mushrooms, has been found to have long-lasting effects on the brain. A single dose of psilocybin has been found to improve mood in people with treatment-resistant depression within three weeks.
Psilocybin has been found to reset brain activity, with patients reporting feelings of being "reset", "reborn", and "rebooted". These feelings of being reset have been associated with the reduction of depressive symptoms. The psychedelic compound may effectively reset the activity of key brain circuits known to play a role in depression.
The effects of psilocybin on the brain are mediated by effector pathways induced by 5-HT2A, a serotonin receptor. The activation of these downstream signalling pathways can influence gene expression, which can then go on to influence synaptic plasticity and brain neurochemistry. These effects are often long-term, underlying the therapeutic efficacy of a single administration of psilocybin to achieve lasting effects.
Studies have shown that psilocybin can alter emotions and brain function up to one month after a single high dose. One week after taking psilocybin, negative affect and amygdala response to facial affect stimuli were reduced, while positive affect and dorsal lateral prefrontal and medial orbitofrontal cortex responses to emotionally conflicting stimuli were increased. One month after taking psilocybin, negative affect and amygdala response returned to baseline levels, while positive affect remained elevated, and trait anxiety was reduced.

Frequently asked questions
Magic mushrooms are specific fungi such as psilocybe cubensis that contain the psychoactive compound psilocybin.
Psilocybin is quickly converted into psilocin after ingestion. Both compounds exhibit affinity for a range of serotonin receptors, particularly the 5-HT2A receptor, which is widely distributed in the central nervous system. Activation of the 5-HT2A receptor can influence gene expression and synaptic plasticity, leading to long-term changes in brain neurochemistry.
Psilocybin has been found to temporarily reset neural networks by disrupting the rigid patterns of communication between brain regions. This desynchronization of brain networks may underlie the therapeutic effects of psilocybin, allowing individuals to break free from excessive rumination and negative thought patterns associated with depression.
Clinical trials have shown that psilocybin, combined with talk therapy, can alleviate symptoms of depression and improve mood in individuals with treatment-resistant depression. The effects can last for several weeks, with patient-reported benefits and reduced depressive symptoms.
While psilocybin shows promising results in treating depression, it should be used under controlled, clinical conditions with a regulated dose and extensive psychological support. More research is needed to fully understand the long-term effects of psilocybin on the brain. Self-medication without proper supervision is not recommended.
