Meditation may calm the mind, but a groundbreaking new study suggests it can also fundamentally reshape the brain’s inner workings—altering its activity patterns in ways that echo the effects of psychedelic substances. This research, published in Neuroscience of Consciousness, reveals that meditation might help practitioners reach a theorized “sweet spot” of brain function known as “brain criticality,” where neural connections are perfectly balanced—not too rigid, not too chaotic—to optimize mental agility and performance.

The study, led by neurophysiologist Annalisa Pascarella of the Italian National Research Council, combined advanced neuroimaging with machine learning to investigate how meditation influences brain dynamics. Researchers used high-resolution magnetoencephalography (MEG) to measure the magnetic fields generated by electrical signals in the brains of 12 highly experienced monks from the Santacittarama monastery near Rome. These monks, all male and aged 25-58, had each accumulated over 15,000 hours of meditation practice, and belonged to the Thai Forest tradition—a branch of Theravada Buddhism grounded in the oldest Buddhist scriptures.

The team examined two distinct meditation styles: Samatha, which focuses attention on a single object (such as the breath) to cultivate mental stability and equanimity, and Vipassana, which encourages open awareness of sensations, emotions, and thoughts as they arise, without judgment. “With Samatha, you narrow your field of attention, somewhat like narrowing the beam of a flashlight; with Vipassana, on the contrary, you widen the beam,” explained University of Montreal neuroscientist Karim Jerbi, senior author of the study.

The results were striking. While Samatha induced a more focused, stable brain state—ideal for deep concentration—Vipassana brought the monks closer to brain criticality, a concept borrowed from statistical physics describing an optimal balance between neural chaos and order. In this state, the brain is stable enough to reliably transmit information yet flexible enough to rapidly adapt to new situations, enhancing processing, learning, and response capabilities.

Interestingly, the researchers observed a decrease in gamma oscillations—a type of brain activity linked to processing external stimuli—during meditation. This suggests meditation may shift the brain from outward engagement toward inward awareness. Experienced meditators showed less difference between their meditative and resting brain states, indicating that their meditative mode had become their default mode.

However, the study also highlights a nuanced reality: meditation is not a guaranteed path to enlightenment. Other research has documented potential downsides, including anxiety, depression, and even delusions in some practitioners. These adverse effects are often underreported, suggesting that meditation’s impact on the brain is more complex than commonly believed.

By employing cutting-edge signal processing and analysis, this research offers new insights into how meditation might sculpt the brain toward a state of optimal function. Yet, as with the lotus that blooms from muddy waters, the journey is neither simple nor without risk. Future studies will be crucial to fully understand meditation’s profound and sometimes unpredictable effects on the human mind.
