By the time we reach our 20s and 30s, many people feel settled into fixed routines. However, growing research on cognitive development shows that the brain continues to learn, adapt, and change throughout life. A new study adds an even more intriguing insight: just seven days of meditation may be enough to reshape neural pathways.
The study, conducted by the University of California, San Diego, observed 20 healthy adults participating in a seven-day retreat led by neuroscience educator and chiropractor Joe Dispenza, D.C. Researchers found that meditation appeared to induce a brain state similar to psychedelic experiences, leading to measurable changes in participants’ thinking, focus, and information processing.
What we know about meditation
Meditation is widely used as a practice for relaxation and stress reduction, but the scientific mechanisms behind its effects have remained less clear until recently. The study used an “open-label placebo” design, meaning participants knew they were receiving a placebo approach—an element that can still produce real effects through expectation.
Before and after the retreat, researchers used functional magnetic resonance imaging (fMRI) to track brain activity and identify changes over the seven-day period. They observed improvements in metabolism, immune response, and other biological markers.
How meditation may reshape the brain
Researchers first noted reduced activity in brain regions associated with mental clutter, suggesting improved efficiency in cognitive processing. This was also linked to increased neuroplasticity, indicating the brain’s enhanced ability to form new connections through regular meditation practice.
Participants also showed increased glycolytic metabolism, which helps the body convert sugar into usable energy.
In addition, the study recorded higher levels of endogenous opioids, the body’s natural pain-relieving chemicals, suggesting improved natural pain control. Both inflammatory and anti-inflammatory immune signals increased, indicating a more balanced immune response. Researchers also identified genetic and molecular changes, including shifts in RNA activity that may strengthen neural pathways and support improved brain function.
The effects of a psychedelic-like brain state
The experiment revealed similarities between brain activity after meditation and patterns typically seen with psychedelic substances. “We’re seeing the same mystical experiences and neural connectivity patterns that usually require psilocybin, now achieved through meditation practice alone,” explained Hemal H. Patel, PhD, senior author of the study and professor of anesthesiology at UC San Diego’s School of Medicine. “Seeing both central nervous system changes in brain scans and systemic changes in blood chemistry underscores that these mind-body practices are acting on a whole-body scale.”
Researchers noted that meditation may produce effects comparable to regulated psychedelic use, including improved emotional regulation, greater stress resilience, enhanced mental well-being, and natural pain relief.
“What we believe, how we focus our attention, and the practices we participate in can leave measurable fingerprints on our biology,” said lead author Alex Jinich-Diamant, a doctoral student in cognitive science and anesthesiology at UC San Diego. “It’s an exciting step toward understanding how conscious experience and physical health are intertwined, and how we might harness that connection to promote well-being in new ways.”
