Hello everyone,
My name is Kaio Shimanski, and I’m a meditation teacher here in Brazil at Pineal Center. I also conduct experiments and research using EEG and other technologies applied to meditation.

I'm the translator of Daniel Ingram's material into Brazilian Portuguese, and we’re currently collaborating with him and the EPRC on EEG projects, using both the Muse Headband and the Cognionics Quick-20 system.

I personally walked the MCTB path, using the Muse Headband and documented the process with graphs and reports—covering Stream Entry, Second and Third Path, Equanimity stages, Fruitions, some jhanas, and other interesting phenomena.

Today, I’d like to freely share with you my first book, which documents this entire process. It’s a guide for DIY techno-meditators—those curious practitioners who want to take a neurodevice and explore their own techniques and inner experiences through a scientific lens.

It’s fascinating to observe the electrical and neural side of the mind in real-time practice.

My goal isn't to prove or disprove anything, but rather to spark curiosity through new perspectives.

The book includes tutorials on handling hardware, software, and EEG data analysis. It also features data and graphs from practitioners in several countries, as well as some analysis of Daniel Ingram’s EEG data during Fruitions.

Navigating the Electric Stream - EEG, Insight and Modern Life - Kaio Shimanski

What happens in the mind during deep meditation? How to access and interpret states of consciousness that often seem invisible?
This was a 4-year work that was born from the convergence of contemplation, science and self-experimentation.

Based on a personal journey — crossed by Buddhist concentration and Vipassana practices, meditation sensors such as the Muse Headband, reports of non-ordinary states of consciousness and brain graphs with EEG — Kaio Shimanski builds an interesting invitation: to explore the mind in an open, empirical and non-dogmatic way.
“Navigating the Electric Stream” proposes a new way of relating to meditation: more conscious, more curious, more connected to the data that the body-mind itself offers. A pragmatic approach to the study of the mind.

329 pages, full of graphs, reports, analysis, illustrations, tables and completely free.

Foreword by Holly Erin Copeland.

This material serves to share my personal journey, but also to document the work and connection of the global HeartMindAlchemy(Facebook) community in the context of neurosensors.

I would like to thank my research, programming partner and friend: Steffan Iverson

And the practitioners/friends of the HeartMindAlchemy community who published their graphs in this work, and also advised me and collaborated with the entire work:

Felipe Anjos(Brazil), Bruno Shanti (Brazil), Kevin Schoeninger (USA), Randy Knudson (USA), Holly Erin Copeland (USA), Neng Freedom (Thailand), Lance Stewart (USA), Vasyl Vernyhora (Ukraine).

To the students who tried the three trainings with me and Muse:

Mustafa Kutrieh, Guilherme Thomaz, Lucas Cypriano, Guilherme Norberto

"These periods of my life were the causes, I believe, that made me curious, interested, and even obsessed with matters of conscience. What began as fear became curiosity. What felt like chaos revealed itself as a path. Meditation, insight, and neurofeedback have not given me all the answers, but they have transformed the way I ask questions. Consciousness is not a destination—it is a current we navigate, moment by moment. This book is not an end, but a continuation. May we keep exploring, questioning, and awakening to the vast, electric stream of being."

For all the technomeditators. - Kaio Shimanski


Thanks a lot (:

Do you think the headband helps you make progress through biofeedback,  or is it a tool for scientific study, or a way to prove attainments?

Because I find as a meditatior that what I experience during meditation, the different sensations and states are a stronger biofeedback signal than the headband.

Biofeedback is helpful when you want to control something you can't directly sense, like blood pressure.

But for something like relaxation, or concentration, or emotional attachemts, you know you if you are tense or relaxed or distracted or concentrating, serene or upset - you don't need a device to tell you that. Isn't it better for meditators to focus on those kinds of experiences rather than the data coming from a technical device?

Thanks

did you notice any discernible difference in the general readings between people with different attainments?

do you think there's any actionable neurological insights about the nature of the human experience that were gained from these experiments?

Isn't this a Shinzen kind of thing? EEG and brain stuff thingling!

Kaio, a few replies would make for a more compelling marketing campaign.

Hey Jim! Thanks for your reply (:

Bio and neurofeedback are really good tools for some aspects of our practices. For example, the Muse algorithm with the birds measures focused mind, and a lot of people use it in their samadhi practices. There is a practitioner in the book from Thailand who completely mastered the algorithm with traditional Anapanasati—3 hours straight, and 100% calm.A

But 90% of the book and the work we've been doing with Daniel and others is about passive measurement of EEG. We only take raw data and convert it into graphs, using the brain rhythms (alpha, gamma, beta, etc.). What's interesting is seeing some rhythm patterns matching with subjective experience. Example: Technique X activates FRONTAL Alpha. Technique Y activates TEMPORAL Gamma, etc.

The practitioner needs to slowly let go of the expectation of results and approach all of this in an open manner, like meditation itself.

And yeah, it's definitely a way to do scientific study—especially now with the help of AI analysis.
As for attainments... I'm not so sure, because we are dealing with electricity in the brain, and specific activation of areas in the brain itself. And as you pointed out, and we all know, the practices and realizations are not only about electricity in the brain.

But yeah, the scientists are trying to find the neural correlates of awakening andthey are advancing. We have some clues—like TP10 gamma activation, which neuroscientists call the "God Spot," and other signatures.

Hey Bahiya! Thanks for your reply (:

We can see differences between traditions. An Zen sangha here practice with Muse and we found that they have delta as their main rythm. And not only one practitioner, but some of them.
With Vipassana, we see aspects of Frontal and Temporal Gamma. Carmelite Nuns activate gamma too in prayers.

We have a method of analysis call similarity  that tell us if my EEG data is similar of someone that practices the same techniques and approach.

We create an website  that shows this type of analysis in relation with Daniel using Muse. Me and other practicioner who works with the same approach,  are very similar with the locations and brain bands of the data of Ingram. But there is other examples, who practices other method, that dont have any match.

Here is the website:

So, it is really interesting to see patterns and rythms and locations in the brain. And after some dozens of graphs, we start to see some repetitions and patterns matching with the subjective experience.

The race with Big Tech guys is to find the neural correlates and create models with them, to generate feedbacks and shortcuts. Like the Journey jhana project and the work of Shinzen Young with Ultrasound (not EEG) devices for deliver equanimity in demand.

Crazy times and a lot of possibilites.

But the tech is an extra for our practice, not a neceessary condition.

thank you for sharing this book. i gained a great interest in EEG, self-research and neurofeedback stuff. may the brain befriend reality!!?!

Thank you Kaio, it is a very interesting project, If I was interested in contributing, what might I do?

Hello my friend,If you (or anyone) have a Muse headband, feel free to reach out — we’re looking for people to help test our open-source app!This is an ongoing, completely free and open-source project. We’ll be releasing a new version of the app very soon.We’re also working on organizing a large EEG database from Daniel, who recorded multiple meditation retreats and experiments using a Cognionics Quick-20 headset. He noted his phenomenological experiences in real time during these sessions.Right now, we’re focusing on organizing his notes, event markers, and cleaning the data — especially targeting his moments of fruition. Once this is complete, the database will be available for other neuroscientists to explore and work with.If you're interested in helping out with data analysis, organization, or testing, let us know!

Yeah university of Arizona. Also jhourney. I've supported them both in the past and worked on EEG sensor machine learning. The consumer grade dry sensors are very noisy. I've donated sensor data (as an untrained participant) to jhourney but they moved to better than consumer grade EEG for their measurements.
