Your Brain Is the Last Private Place. For Now.

What if the most private place you have — not your phone, not your diary, but your own mind — started to become readable? Not in some distant sci-fi future. Now.

That is the uncomfortable and fascinating question at the center of this episode. Mizter Rad sits down with Dr. Jörn Rickert, a German neuroscientist and entrepreneur who has spent his career quite literally inside the human brain. He co-founded CoreTec, a company that builds brain-computer interface implants that read brain activity and respond to it in real time. In 2026, CoreTec performed the first human implantation of its Brain Interchange system in Seattle, helping a stroke patient recover movement in his arm.

Then Jörn did something unexpected. He stepped away from the implant world and started something completely different: Neudio, a company that uses music — personalized to your brain waves in real time — to change your mental state. No surgery. No electrodes. Just neuroscience and sound.

Brain-Computer Interface Technology: What Is the Brain Actually Doing?

Before we can talk about brain-computer interface technology, we need to understand what the brain actually is. Jörn puts it simply:

"The brain is simply the computational engine that makes from all what we see, from all our perception — vision, hearing, feeling — then we have experiences, and all this is processed in real time to make decisions, which in the end result in movements from your body and your voice. So it is essentially an input-output machine that controls all our behavior."‍ ‍

When that machine breaks — through stroke, injury, depression, addiction, chronic pain, or age-related diseases like Parkinson's and Alzheimer's — the consequences are profound. And that is where neurotechnology steps in. According to Jörn, the field has two main applications. The first is therapeutic: using brain stimulation to treat neurological diseases, retrain damaged neural circuits, and bring the brain back to a healthy state. The second is enhancement: using brain-computer interface technology to augment cognitive abilities in healthy individuals. We are firmly in the first phase right now. The second is coming.

From Brain Implants to Music: Two Very Different Solutions

CoreTec's Brain Interchange is a precision platform. It is implanted inside the skull and creates a long-term, stable communication channel between the brain and external devices. It reads brain activity, decodes movement and speech intention, and can stimulate specific areas with precise electrical signals — all in real time. Jörn explains what makes this approach unique:

"The brain is so tiny in its structures, tiny currents. And your head, your skin, the bone, the muscles that are there, they all isolate the brain and protect it from reading its thoughts or doing precise stimulation. So that's why we said, if we want to deliver precision therapies, then you need an implant."‍ ‍

The key concept behind CoreTec's approach is something called closed-loop stimulation. Jörn breaks it down:

"Closed loop essentially means that you listen to the effect of what you're doing to the brain. You listen to the brain and then you stimulate on demand, and you can react to your own stimulation and you can time stimulation to the activity of the brain."‍ ‍

This real-time feedback loop allows the system to induce lasting changes in the brain's state — not just suppress symptoms, but potentially reprogram the brain itself. The journey from CoreTec to Neudio began when Jörn's friend and collaborator, Professor Andrew Jackson from the UK, made a surprising discovery: that music, timed precisely to your brain waves, can produce effects similar to electrical brain stimulation.

"He found out he can double his brain waves or half his brain waves just by listening to music that had been timed to his brain. I was like, okay, that's really cool. That's finally a neurotechnology that is pleasant and effortless and it allows a targeted stimulation."‍ ‍

How Neudio Turns Your Favorite Music Into a Brain-Computer Interface

The difference between regular music and Neudio's approach is personalization. As Jörn explains, all music has an effect on the brain — but until now, everyone hears the same MP3. Neudio reads your brain waves through external sensors (headbands, earphones, or patches that are already commercially available), and modulates elements of the music you are already listening to — in real time — so that specific sounds hit your brain at precisely the right moment in the wave cycle. This pushes your brain waves up or down, toward concentration, relaxation, or pain relief.

The company currently has a prototype plugin for Spotify. If you are a jazz listener, for example, the rhythmic elements of the drums would be subtly altered to synchronize with your personal brain activity. You would still be listening to your own music. It would just be working harder for you. This is not passive listening. This is a non-invasive brain-computer interface built around sound.

Brain Data, Privacy, and the Real Question Nobody Is Asking

One of the most provocative moments in this conversation comes when Mizter Rad asks about privacy. If brain implants are reading electrical signals from our thoughts, who owns that data? Jörn's answer is surprising — and a little unsettling:

"What kind of person you are, your inner thoughts and feelings — okay, maybe not what you just thought, but is it so relevant what you thought? You're defined by your actions, your impressions. And that is read by cameras, health gadgets, your behavior on the internet. They can already know who you are. You can add very little by brain reading right now."‍ ‍

In other words, the last bastion of privacy is not as protected as we think — and the threat is not coming from brain implants. It is already here, through our phones, our faces, and our browsing habits. This connects to a broader theme the show has explored before. In the episode with James Glattfelder on consciousness and information theory, Glattfelder argued that our models of reality shape the world we build. If the data flowing through our digital behavior is already a more accurate portrait of who we are than any brain scan, then the real frontier of privacy is not neural — it is behavioral.

The Intersection of Psychedelics, Music, and Brain-Computer Interface Therapy

The conversation takes a personal turn when Mizter Rad shares his own experience at a ceremonial session in Colombia, where a live drummer played music that seemed to physically amplify the effects of the medicine. Jörn confirms the science behind the experience:

"Combining this — you know, with music that already has an effect — but now you give the music an additional effect, like an additional targeted modulation of brain activity. That is definitely where we are going."‍ ‍

This connects to an episode the show has explored from a different angle. In the conversation with Carina Cunha, founder of Satori Health, Mizter Rad looked at the therapeutic use of psychedelics for mental health. What Jörn adds is the next layer: what happens when you pair a brain-rewiring substance with music that is actively tuned to your brain waves in real time? The clinical possibilities are significant. Neudio is already preparing collaborations in this space.

The Business Reality: Who Pays for Brain Technology?

Building at the frontier of neuroscience is not just scientifically hard. It is commercially brutal. Jörn is candid about this:

"If you have a therapeutic device, insurance pays when it's effective. But brain implants require training surgeons, maintenance, calibration. It's not like a pharmaceutical where you pay one billion and you have a nice pill everybody can just take."‍ ‍

The regulatory burden on implants is growing — increasingly comparable to pharmaceuticals — but without the same economics on the other side. Market penetration is slow. Surgeons need training. Patients are cautious. Non-invasive neurotechnology, like Neudio, currently sits in a far lighter regulatory environment. And that gap is, for now, an opportunity.

What the Next 50 Years Will Look Like for the Human Brain

When Mizter Rad asks Jörn to look ahead across five decades, the answer is layered. On the brain specifically: first, a brain reset — the ability to bring a damaged or diseased brain back to a baseline healthy state using stimulation or psychedelic-assisted therapy. Then, a permanent reprogramming: not just treating symptoms but actually changing the underlying network for the long term. Then, augmentation: extra senses, enhanced cognition, augmented communication — the ability to share not just words but mental images directly. But Jörn's deeper worry is not about the brain. It is about society:

"We don't need office jobs anymore. We don't need manufacturing jobs anymore because we have robotics and AI to do this. So how are societies going to be organized? Will we have a new form of socialism so that the benefits are distributed among the society? Or will we end up in a society where most people are poor, offering their manual labor in competition to robots?"‍ ‍

This connects directly to what Gizem Gumuskaya explored on this show about anthrobots and synthetic biology — the question is not only what the body becomes, but who benefits when biology and technology merge. And to what Elio Challita discussed about insect-inspired micro-robotics: the smallest machines, whether biological or engineered, may carry the largest social implications.

The Last Private Place

Mizter Rad closes the episode with something worth sitting with: "Today reminded me that the most interesting frontier is not the body. It is the mind. It's not intelligence, not memory, but something harder to define. The raw, the unfiltered, the private experience of being you. And that is worth protecting."‍ ‍

The brain-computer interface is not just a medical device. It is the beginning of a conversation about what we are willing to share, what we are willing to become, and what we will insist on keeping for ourselves.
