What is neuroplasticity?
Neuroplasticity refers to the brain's ability to change and adapt to external stimuli over time. This includes neuronal death, neurogenesis (new neurons), creating new neuronal pathways and creating new synaptic connections.
-
Why is it beneficial to increase neuroplasticity?
Neuroplasticity is associated with learning, new experiences, and memory formation. The more efficiently the brain is able to create new neurons and new synaptic connections, the better we are able to perform these tasks. It can also benefit those with neurological disorders.

How do magic mushrooms improve your brain's neuroplasticity?
Magic mushrooms are thought to increase your brain's neuroplasticity via the 5HT1A serotonin receptor. In rodent studies, it has increased the rate of neurogenesis in the hippocampus and prefrontal cortex.
Up until recently, we believed the human brain stopped developing after childhood.
Today, we understand that our brains have an incredible propensity to adapt and change, even throughout adulthood. Our experiences — both joyful and traumatic — can cause the brain to both recognize and create new synaptic connections, a quality known as neuroplasticity.
And when we talk about neuroplasticity, we aren’t talking about an abstract psychological concept, but a tangible, measurable, and observable change in your brain's structural and functional connectivity.
Ongoing research into psychedelics like psilocybin magic mushrooms, MDMA, LSD, mescaline, ketamine, and more continue to reveal what Terrence McKenna was referring to in the Food of The Gods, the counterculture manifesto on mind-altering drugs and hallucinogens.
In it, the ethnobotanist posits that psychedelics change the way your brain works. And not in the negative way we were taught to believe they would, but in a positive and meaningful way that encourages continuing brain development and healthy aging.
That is if you do them in the correct set and setting.
To put it scientifically, there is continually emerging evidence that magic mushrooms improve your brain’s neuroplasticity.
In this article, we’re going to dive deeper into what neuroplasticity is, its importance for optimizing our health, longevity, and stress resilience, and some of the research behind psilocybin and its role in promoting neuroplasticity.
Let’s jump straight in.
What is neuroplasticity?

Neuroplasticity isn’t just a result of taking psilocybin or other substances.
Sometimes referred to as brain plasticity or neural plasticity, neuroplasticity describes your brain’s unique ability to create new synaptic connections and neural pathways.
It's when your brain is rewired to function in different ways, which it does by growing and reorganizing its neural networks in response to new experiences, learning new skills, and environmental stimuli. This phenomenon allows the brain to adapt to new circumstances, learn new information, form new memories, and recover from injury.
In addition to psychedelics and experience-dependent changes, neuroplasticity can be influenced by factors such as age, sleep, stress, and various forms of brain stimulation.
For example, studies have shown that certain forms of stimulation, such as repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS), can modulate activity in specific brain regions and potentially enhance certain cognitive functions.
And neuroplasticity occurs at multiple levels, from molecular changes in individual neurons to changes in large-scale networks involving multiple regions of the brain.
For example, when we learn a new skill, such as playing a musical instrument, new neural connections are formed and strengthened in response to repeated practice. This leads to an increase in the efficiency of communication between neurons, resulting in improved performance.
However, meaningful neuroplasticity relies on the availability of neurons in the brain, which brings us to neurogenesis.
The role and importance of neurogenesis in neuroplasticity.

Neurogenesis is creation, and neuroplasticity is (re-)organization.
Neurogenesis is an essential part of neuroplasticity and a prerequisite for meaningful structural and functional changes in your brain.
You see, neurogenesis increases the pool of neurons available for rewiring and reorganization, or neuroplasticity.
It starts with the division of stem cells that, after turning into neurons, migrate to their final destination where they integrate into the existing neural network and establish new connections.
Neurogenesis mainly occurs in the hippocampus and plays a crucial role in learning, memory, mood regulation, and stress response. For example, studies have shown that increased neurogenesis in the hippocampus is associated with improved learning and memory, while decreased neurogenesis has been linked to depression and other mood disorders.
In this way, neurogenesis plays an important role in the overall process of neuroplasticity by providing the brain with the building blocks necessary for adaptation and change.
How does this apply to you?
Well, prolonged exposure to stress is a given these days.
It's well-known in the scientific community that chronic or prolonged exposure to stress, whether physical, psychological, or social, can dramatically reduce your rate of neurogenesis. This subsequently leads to decreased cognitive function, which manifests as brain fog, poor memory and learning capacity, and fatigue, and increases your risk for mood and anxiety disorders.
So if you feel overly stressed or overwhelmed, if brain fog and fatigue are becoming the norm, you may want to consider introducing practices and supplements that stimulate neurogenesis.
Supplements include neurotrophic compounds like psilocybin, which we'll get into the next section, or lifestyle factors like experiencing novelty and enriched environments, getting good sleep and plenty of exposure to sunlight, aerobic exercise, and meditation.
This will in turn support neuroplasticity mechanisms, helping your brain become more adaptable and building your resilience to stress and disease.
Surprisingly, acute stress can actually improve your rate of neurogenesis, potentially enhancing certain forms of learning and memory — but only in the short term. It's your brain's way of helping you learn to adapt to acutely stressful situations, such as learning a new skill or overcoming a challenge at work.
The take-home message?
Understanding the underlying mechanisms and factors that contribute to neuroplasticity has important implications for a wide range of fields, including education, rehabilitation, and mental health.
Now, let's take a look at how psilocybin stimulates neurogenesis and neuroplasticity, and the impact it has on your cognition, behavior, and mood.
How do psilocybin magic mushrooms improve neuroplasticity?

Psilocybin has been studied to induce neurogenesis and neuroplasticity in two key brain regions:
- The prefrontal cortex (PFC), which plays a central role in executive function, or the ability to self-regulate and plan ahead. Examples of executive function include short-term memory, problem-solving, controlling your behavior and impulses, delaying instant gratification, regulating your emotions, planning, and making decisions
- The hippocampus, which plays a central role in learning and memory.
The changes to these brain regions induced by psilocybin are believed to result from the neurobiological pathways psilocin — psilocybin's active metabolite — activates.
There are 2 primary pathways:
- Serotonin 5-HT2A receptors in the PFC: Psilocin, psilocybin's hallucinogenic metabolite, confers its mood-lifting and psychedelic effects by activating serotonin 5-HT2A receptors. These receptors play an important role in learning and cognition, as well as anxiety, depression, fatigue, and insomnia. Consistent studies also suggest that they exert powerful control over BDNF expression, and this may be a key mechanism underlying the therapeutic effects of psilocybin.
- Glutamate signaling in the PFC: In human studies, PET imaging has shown that psilocybin increases glutamate signaling in the PFC. This is theorized to be important for psychedelic-enhanced plasticity since glutamate stimulates the production of brain-derived neurotrophic factors (BDNF).
After psilocybin is converted into psilocin, it acts on a serotonergic receptor called “2A” (5-HT2AR).
This in turn activates specific pathways, or cascades of different proteins communicating and transferring a signal.
Following the activation of these cascades, the two abovementioned neurotransmitter systems — the inhibitory serotonergic system, and the excitatory glutamatergic system — are activated.
The activation of these systems subsequently leads to the release of brain-derived neurotrophic factor (BDNF), a direct indicator of neuroplasticity. Indeed, high levels of BDNF in the brain are associated with increased neuroplasticity, and low levels with mood and neurological disorders.
Psychedelics also influence neuroplasticity indirectly by affecting the transcription of plasticity-related genes and proteins, which modulates the expression of other genes and proteins involved in neuroplasticity.
In a 2018 study, researchers demonstrated the role of serotonin 5-HT2A receptors in neuroplasticity by giving participants a drug that kept psilocin from activating it. This stopped psilocin from binding with the receptors, along with its ability to promote neuroplasticity.
In a 2020 study, researchers demonstrated an increase in neuroplasticity mediated by higher glutamate levels in the PFC, but not the hippocampus, after psilocybin administration.
One study conducted on rodents at Johns Hopkins University showed that psilocybin at low doses was able to increase the number of newborn neurons in the hippocampus. The study was conducted around fear conditioning, and mice on the low dose were able to extinguish fear conditioning faster than the placebo and high-dose groups. However, it's generally thought that the 1A serotonin receptor mediates this, not 2A.
In another study, researchers showed that psilocybin rapidly increased gene expression related to neuroplasticity in the rodent brain. It was especially prevalent in the hippocampus and PFC.
As demonstrated in the illustration below, researchers in a 2020 human clinical trial found that structural and functional changes in the brain lasted at least 1 month after the participants' psilocybin journies, suggesting the presence of lasting neuroplastic changes.
During the trial, they discovered a staggering increase in resting-state functional connections across the brain from baseline to 1-week and 1-month post-psilocybin journey. The lines in red show new and strengthened connections, whereas the lines in blue show weakened connections.

While it's too early to tell to what degree magic mushrooms will be applied in the context of neurological diseases, early evidence from clinical studies on psilocybin and other psychedelics demonstrate statistically significant improvements in patients with treatment-resistant anxiety, depression, PTSD, traumatic brain injury, cluster headaches, and postpartum depression. These improvements are primarily attributed to the sudden increase in neuroplasticity in the brain.
What does this mean for the everyday mushroom user?

It means that you might be replacing your conventional pharmaceuticals with psychedelics sometime in the near future. It also means that you could use it as a tool to facilitate flow, whether you're an entrepreneur, artist, musician, or mathematician.
Psychedelics induce changes in processes that persist beyond their initial administration, sometimes for up to 6 months. This suggests a biological adaptation, or neuroplasticity. Especially when you are intentional about your use, or couple it with a coach, therapist, or guide of some kind.
Some networks, such as those in the PFC regulating cognition, may remain plastic throughout life. Mediating this process and facilitating the rewiring of certain networks may be possible through the use of psychedelics.
The neuroplastic changes caused by a psychedelic trip are why you might feel inclined to learn new skills or become more creative after the experience. Or it might be why you're able to leave your house without crippling anxiety. Neuroplasticity is the outcome of learning and new experiences, and the profound psychedelic experience often lends itself to greater openness, creativity, expression, and idea formation.
Many psychonauts also express the ability to “see things differently” after a magic mushroom journey — which is another way of describing neuroplastic changes. For example, magic mushrooms can sometimes help us resolve a problem that seemed unresolvable before, whether it’s a math, romantic, or social problem. Could this be the result of creating new neuronal pathways or having greater synaptic connections?
We think so.
It’s really hard to say what neuroplasticity means in terms of measurable effects for someone who is completely healthy, stress-free, and doesn't have any goal or intention behind their use. But even stress and coping affected by neuroplasticity.
What's your experience with psychedelics and neuroplasticity? Have you felt those improvements in mood, cognition, mindset, and overall adaptability to whatever came your way in the days and weeks that followed? We’d love to hear from you in the comments.
