Study of Buddhist Monks Finds Meditation Alters Brain Activity

Study of Buddhist Monks Finds Meditation Alters Brain Activity

If you’ve ever considered practicing meditation, you might believe you should relax, breathe, and empty your mind of distracting thoughts. Novices tend to think of meditation as the brain at rest, but a new international study concludes that this ancient practice is quite the opposite: Meditation is a state of heightened cerebral activity that profoundly alters brain dynamics.

Researchers from the University of Montreal and Italy’s National Research Council recruited 12 monks of the Thai Forest Tradition at Santacittārāma, a Buddhist monastery outside Rome. In a laboratory in Chieti-Pescara, scientists analyzed the brain activity of these meditation practitioners using magnetoencephalography (MEG), technology capable of recording with great precision the brain’s electrical signals.

The study focused on two classical forms of meditation: Samatha, a technique that focuses on sustained attention to a specific objective, often steady breathing, with the aim of stabilizing the mind and reaching a deep state of calm and concentration, and Vipassana, which is based on equanimous observation of sensations, thoughts, and emotions as they arise in order to develop mental clarity and a deeper understanding of the experience.

“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,” explains Karim Jerbi, professor of psychology at the University of Montreal and one of the study’s coauthors. “Both practices actively engage attentional mechanisms. While Vipassana is more challenging for beginners, in mindfulness programs the two techniques are often practiced in alternation.”

The researchers recorded multiple indicators of brain dynamics, including neural oscillations, measures of signal complexity, and parameters related to so-called “criticality,” a concept borrowed from statistical physics that has been applied to neuroscience for 20 years. Criticality describes systems that operate efficiently on the border between order and chaos, and in neuroscience, it is considered a state optimal for processing information in a healthy brain.

“A brain that lacks flexibility adapts poorly, while too much chaos can lead to malfunction, as in epilepsy,” Jerbi explained in a press release. “At the critical point, neural networks are stable enough to transmit information reliably, yet flexible enough to adapt quickly to new situations. This balance optimizes the brain’s processing, learning, and response capacity.”

During the experiment, the monks’ brain activity was recorded by a high-resolution MEG system as they alternated from one type of meditation to the other with brief periods of rest in between. The data were then processed with advanced signal analysis and machine learning tools to extract different indicators of neural complexity and dynamics.

Striking a Balance

Results published in the journal Neuroscience of Consciousness show both forms of meditation increase the complexity of brain signals compared to a brain at rest. This finding suggests the brain in meditation does not simply calm down but rather enters a dynamic state rich with information. At the same time, the researchers observed widespread reductions in certain parameters linked to the global organization of neural activity.

One of the most striking findings in the analysis of the criticality deviation coefficient showed a clear distinction between Samatha and Vipassana. This indicates that, although both practices increase brain complexity, they do so through different dynamic configurations, consistent with their subjective experiences. In other words, Vipassana brings the practitioner closer to the balance of stability and flexibility, while Samatha produces a somewhat more stable and focused state. According to researchers, the closer the brain gets to this critical state of balance, the more responsively and efficiently it functions. This is reflected, for example, in a greater capacity to switch tasks or to store information.

These days, new versions of AI chatbots don’t just launch; they’re unshackled and released to the public following government scrutiny. OpenAI’s new GPT-5.6 models were – like Anthropic’s Claude Mythos and Fable – apparently too powerful to just launch; but now, after some tinkering, they’re available to you, dear customer.

In practice, it simply means that the new GPT-5.6 models are very powerful and smarter than before. In its introductory post, OpenAI shared a bunch of graphs showing just how much better GPT-5.6 is than the competition, whilst using fewer tokens and generally costing less.

OK, great. But GPT-5.6 is not just one model; it comes in three distinct flavors: Sol, Terra, and Luna. So what do different kinds of users get, what should they pay for, and which models should they (mostly) use? Let’s dive in.

Free users get (almost) nothing

Sorry; if you’re not a paying customer, you’ll have to make do with OpenAI’s previous flagship model, GPT-5.5. Any sort of access to GPT-5.6 models requires a subscription of some sort. Fortunately, GPT-5.5 is still quite capable at most tasks, but if you want the best of the best, you’ll have to cough up the dough.

There’s an exception to this: Free and Go users can access GPT-5.6 through ChatGPT Work. More on that below.

If you’re a Plus or Business user, you can only get Sol (the most powerful model) at medium and higher effort settings. There’s another, higher level of performance called Sol Pro, but that’s only available for Pro and Enterprise users.

In terms of availability per one million tokens, the prices are: $5 input and $30 output for Sol. $2.5 input and $15 output for Terra, and $1 input and $6 output for Luna.

Sol, Terra, or Luna?

Why are there three models in the first place? Well, OpenAI always had a multi-tier model; for example, previously users were able to choose a “mini” version of the main model to get results done cheaper. Now, the model has been split into three tiers.

If you’re a paying customer, you’re free to use all three. But you know how it is in the world of LLMs: If you pick the smartest one, your usage limits will get hit faster (yes, there are always usage limits, even if you throw a ton of money at OpenAI).

In the simplest sense, GPT-5.6 Sol is the smartest model, Terra is in between (with roughly GPT-5.5 level of performance), and Luna is the cheapest, fastest, but also least capable of the bunch.

The breakdown is as follows: Terra is a “balanced” model for everyday work. That’s the one you should be asking most of your questions. Don’t underestimate it, though, as OpenAI claims it performs better than Anthropic’s Fable 5 in some cases.

Luna is cost-efficient, and should be used for easy, non crucial everyday tasks; think recipes and movie recommendations. Again, OpenAI says it outperforms Anthropic’s Opus 4.8 in some cases, so it’s not a slouch, either.

Sol should be reserved for coding, deep research, planning, and cybersecurity: The most demanding tasks. Of course it comes at a (literal) cost: While OpenAI claims it spends less tokens than Anthropic’s Fable 5, Sol will still hit usage limits a lot faster than the other variants.

Fun fact: If you ask GPT-5.5 about any of this, right now, it’ll give you completely wrong answers. Hopefully OpenAI will fix this soon.

Wait, what’s this ChatGPT Work thing, then?

Oh yeah, OpenAI also launched ChatGPT Work, which is a new agent in ChatGPT that can access and take actions on your apps and files, and work in the background until a task is finished. It’s powered by Codex (OpenAI’s software engineering agent) and GPT-5.6. Think about it as your buddy that will go through your emails and files, browse the web, fetch the relevant data, and create that presentation your boss wants before the day is done.

ChatGPT Work is rolling out to Pro, Enterprise and Edu users first on web and mobile; this will be expanded to Plus and Business users “over the next few days.”

On the desktop, Work is available for everyone, including Free users.

Oh, and one more thing: The fact that ChatGPT Work has a built-in browser also means that OpenAI is sunsetting its standalone web browser, Atlas. Sorry.

How about GPT Live?

GPT Live is a new version of ChatGPT Voice and it will show up when you start talking to ChatGPT.

We’ve covered this in more depth here, but the bottom line is that GPT Live can listen and speak at the same time, allowing it to keep up a more realistic conversation.

Wrapping it all up

The new GPT-5.6 model is smart. It comes in three flavors: Luna, Terra, and Sol, with Sol being the most capable variant, Luna the most affordable one, and Terra somewhere in the middle. You can currently only get them on paid tiers, unless you’re using ChatGPT Work on desktop. And ChatGPT Voice has also gotten smarter with GPT-Live underneath, a model that can listen and speak at the same time.
