A research translation and complementary practice. A bounded experiment in recovering access to what the bioelectric system has been blocking — for readers who have already followed the signal this far on their own.
If you are here, you have probably been reading Hoffman, Levin, Kastrup, Barrett, Huberman, Attia — and you have probably optimized the inputs: sleep, HRV, supplements, breathwork. The metrics moved. The pattern did not. The map they are drawing only sharpens a problem none of them resolves for you. The premise of this practice starts there.
The body is not a machine with a mind attached. It runs a prediction — a model trained on years of high-arousal output that keeps spending ahead of demand long after the demand is gone. That model is held at the level of the nervous system, and one scale down, in the bioelectric configuration of the cells — and most of the signal underneath it has been quiet since you learned to perform.
You noticed it first when the milestone landed and the feeling that was supposed to follow didn't. The chassis was optimized. The operating system kept running. Nothing downstream of that quite delivered what it was supposed to.
You have had glimpses of something real — in the reading, in meditation, in the occasional afternoon when the noise drops out. And then the mind comes back online and absorbs the glimpse into another model, and nothing actually changes. That loop is the problem this practice is built around.
Recovery, here, does not mean returning to a previous baseline. It means recovering access to what the bioelectric system has been blocking — the signal, the felt information, the signal traffic that's been held quiet while the analytical layer has been allowed to run everything.
We replace the body-as-machine with a two-scale model: at the nervous-system scale, a predictive system that allocates the body's resources ahead of demand from a trained model (Barrett); one scale down, a bioelectric configuration that holds pattern information beneath chemistry (Levin). The two are cited where they converge — on predictive control — not beyond it.
Published research — regeneration, pattern memory, non-neural cognition — is summarized with explicit attribution boundaries. We show where the science ends, where testimony begins, and why the distinction matters to anyone still running their body from their head.
What actually happens inside a Tong Ren session, described in the same register as the rest: observed patterns, not promises. What tends to come back online. What the practitioner is doing. What the mechanism is not known to be.
“Bioelectric signaling functions as a prepattern that instructs anatomical form. It can be read, written, and rewritten — and it is active long before, and far outside, the nervous system.”
Over the last fifteen years, a body of peer-reviewed work has established that cells and tissues communicate through bioelectric signals — and that these signals carry pattern information that chemistry alone cannot explain.
A parallel body of work runs at the scale of the whole organism. Lisa Feldman Barrett's peer-reviewed research on allostasis and the predictive brain describes a nervous system that spends the body's resources ahead of demand from a model trained by experience — and keeps running that model after the demand is gone. A 2025 7-Tesla fMRI study (Zhang et al., Nature Neuroscience) mapped that anticipatory network to a specific anatomical address. Barrett's account at the organism scale and Levin's at the cellular scale arrive at a structurally similar insight from opposite directions: a system that holds a trained configuration and returns to it after the inputs change. The parallel is structural, drawn from their respective published work — not a shared finding. Barrett restricts her model to brains and complex nervous systems; Levin extends his further; whether the two scales are aspects of one problem is an open question neither has answered in published work. Neither has endorsed the practice on this site.
That research does not prescribe treatment. It does not claim that bioelectric techniques heal. What it does is establish the body as a signaling system — a claim that, fifteen years ago, would have been outside the scientific mainstream and now is not.
The practice described on this site sits downstream of that shift in framing, not inside the research itself. That distinction is maintained throughout.

Analytical by training. Still operational, still performing — and quietly aware that the operating model which built everything in your life has become the thing you cannot step outside of.
You have read Hoffman on the interface theory of perception, Levin on bioelectric pattern control, Kastrup on analytic idealism, Barrett on the predictive brain, Huberman on the mechanics of state, Attia on span and the decades of decline. You have probably built a serious optimization stack on top of all of it — and watched the metrics improve while the pattern underneath stayed exactly where it was. You have also read enough bad science to distrust most of what gets sold in the adjacent market. You are not looking for belief. You are looking for something observable, bounded, and honest about what it does and does not know.
And you have probably noticed that the people doing the best work in this territory rarely address the part that matters most to you: what to actually do with a body while the map is still being drawn. That gap — epistemically honest, practically unresolved — is what this practice occupies.
If that is not you, this is probably not the right practice. That is a feature of the work.
The activation does not stand down when the meeting ends. The body stays configured for threat even when the environment is not. What this site calls a defended attractor state — drawing on the attractor-state framework from bioelectric cognition and neuroscience research, a signal pattern the system keeps defending against the grounds having changed — shows up, in practice, as the thing you cannot think your way out of. The work below addresses that layer directly.
The Bioelectric Reset Protocol runs as a research-style sequence: a pattern assessment opens it, six sixty-minute Tong Ren sessions follow, and a structured debrief closes it. Each session is sequenced and adjusted to work the underlying pattern your system keeps returning to, and is recorded and sent to you within a day so you can revisit it between meetings. Cadence is yours to set — weekly, biweekly, or a mix — most complete the protocol over ten to twelve weeks.
By the close, you have either observed something that changes how you see your own system, or you haven't. Either outcome is the engagement delivering what it should.
Pricing is covered on the pattern assessment call.
If you would rather observe before scheduling a 1:1, a free remote group session runs weekly. No cost, no obligation, observer role — you sit in, watch the protocol run, and decide from there.

This practice is run by Johanna Farrimond. Twenty years in IT before this work — a decade inside classified government networks, including a period as Head of Security, and a decade in commercial IT in Windsor. Physics undergraduate; Electrical Engineering; M.S. in Information Assurance, with Honors. A professional life built on the premise that systems are legible, mechanisms are traceable, and claims should be attached to evidence or discarded.
I encountered Tong Ren through personal experience, during a period when the tools I had been trained to use were not reaching the thing I was trying to address. My first response was the appropriate one: this cannot be what it appears to be. I watched, took notes, ran the experiment on myself first. What I observed did not fit the models I had been using — and did not fit the explanatory frameworks most practitioners offered. Then I read Michael Levin, and his work gave me the closest vocabulary I have found for what I was observing. Not a proof. Not an explanation. A framework that made the question well-formed. Bioelectric Recovery was built to do the one thing the skeptic needed: separate what is observed from what is claimed, every time.
