Here it is - the official, revised, peer-reviewed version of my Platonic Space paper. mdpi.com/2409-9287/11/5/161 Of all the many unpopular positions I’ve taken over the decades - bitter controversies around the origin of left-right asymmetry in embryogenesis, bioelectricity and genetics, diverse intelligence, etc., this one has by far generated the most pushback: serious (grateful for those!) and energetic attempts to move me to other views, pleas to just drop it and not talk about it (for several different reasons), nasty emails and accusations, impacts on reviews of papers that have nothing to do with this, etc. Kind of amazing to me how incendiary this is. What can I say... Our job is to call it as we see it, and right now for me, this is it. Apologies to collaborators and colleagues for any shrapnel! Time will tell if this pans out or not; I've placed my bets. And btw, if you think this stuff is weird and uncomfortable, just wait… There’s much more on the way. The knob turns slowly but as long as the data keep coming, I'm going to say what I think it all means and follow it to the next steps it enables. Buckle up!

I'm so sad that @danieldennett isn't around for this. He would have really, really disliked the dualist conclusion - I can just see him shaking his head with that "oh no, no...". But I know he'd have read it carefully, steel-manned the viewpoint, and then critiqued all the right spots. Would have been delightful to argue to him about this. I wanted to polish it before showing it to him, but it wasn't in time. Funny enough, and he'd not have remembered this I'm sure, but it's an echo of 1991, when I was an undergrad in his philosophy of mind course and did my final paper on pretty much this topic (mostly focused on the ingressing minds idea and math, we didn't have the biology or computational results then of course). He hated the conclusion (as I knew he would) but was an absolute gentleman in giving it a fair shake and engaging with the arguments, especially the few he couldn't shoot down.

New #preprint - @HananelHazan "Computational Framework for Identifying Ion Channel Mutation-Compensating Interventions" biorxiv.org/content/10.64898… How to fix hardware problems (an ion channel mutation), in software (without fixing the mutation)? We took a computational approach to this question in neural tissues - a system that helps discover what other channels could be opened/closed via pharmacological agents (electroceutical drugs) to compensate for the mutation's effects on neural firing patterns. Abstract: "We present an automated pipeline for finding therapeutic interventions in channelopathies. It starts from patch clamp recordings of the variant channel, searches over the pharmacologically accessible conductances, and says which currents must change and by how much. The intervention never touches the mutated channel: it compensates by modulating others. The feasibility of this approach is demonstrated through two computational strategies, each addressing a specific capability gap. First, we employ high-fidelity NEURON simulations combined with exploratory search algorithms to model two clinically described variants, and identify "stability windows" in which channel modulations restore the reference firing pattern. The compensating configurations are degenerate: 37 conductance triples fire the same number of action potentials at every one of the 35 injected-current levels, and the 10,780 triples reaching the best intervention value produce only six distinct firing patterns. Second, to address the computational cost of such detailed modeling, we implement a differentiable Hodgkin-Huxley model in PyTorch. Applied here to theoretical mutation screening, this approach trades granular detail for speed, treating the search as a continuous optimization problem that makes very large, non-local searches of the conductance parameter space affordable: the differentiable forward model evaluates 34,000-64,000 candidate parameter sets per second on a single consumer graphics card, against 11.9-16.9 per second for the non-differentiable pipeline on a 72-core node. The gain arises from forward-model throughput feeding a search rather than from the gradient itself, and it is what makes the 32,000,000-point survey of the solution topology reported here affordable. These computational predictions can inform practical drug development and high-throughput screening by naming the currents that must change and by how much."

Meet The Scientist Redefining Intelligence With Michael Levin "There's a FALSE assumption that Intelligence and cognition is rare in the tree of life and late in the evolutionary story. This is very wrong". "Many of the characteristics, morphology, behaviour, phenotypes of organisms are not determined by their genes." "Learning only needs a dynamical system made out of interactions that give way under stress. No genes necessary" The remarkable @RichardWatson90, a coauthor on many papers with @drmichaellevin is live now! ⬇️

Lots of interesting stuff here!
1/3 Conscious AI and Biological Naturalism. A veeery loooong time in the making, but I'm happy to say that the full collection is now out in @BBSJournal 🔥 I deeply thank all commentators - of fifty commentaries! - for their wise, broad, and deep opinions on this critical topic. I also thank them for their saintly patience. 🙏🏽 I remain highly skeptical about the prospects for conscious AI (for silicon digital systems), but I've learned an enormous amount from the privilege of engaging with these commentaries. Hands down one of the most rewarding experiences of my professional life. My hope is that - whether you agree with me or not - having such a diversity of views collected in one place will serve a useful resource for discussions about consciousness and AI. The original target article is available here: cambridge.org/core/journals/… My response "The stuff matters: consciousness, computation, and biology" was published just now, and is here: cambridge.org/core/journals/… And the set of 50 commentaries are collected here: cambridge.org/core/journals/… Unfortunately these are not open access. I will try to remedy that, at least for the target & response. FWIW there's a more accessible version of my view on the topic here in @NoemaMag noemamag.com/the-mythology-o… and also a short @TEDTalks from earlier this year ted.com/talks/anil_seth_why_…

Can self-interested, self-improving, self-replicating agents learn to cooperate? Our new paper, Tapes Together Strong, shows they can: when social behavior, computation, and reproduction share one energy budget, cooperation evolves from scratch. arxiv.org/abs/2609.10817 🧵

We wrote a tutorial guide on voltage imaging, now out in Neuron: authors.elsevier.com/a/1nlgh…. Indicators, microscopes, and software have all advanced to the point that it's not so hard -- you can now directly watch the electrical activity of neurons in live animals or in culture.

New #preprint in computational modeling of #bioelectricity! @cellbioelectric and Joel Grodstein: "Membrane voltage and connexin expression work together to enhance tumor growth and metastasis in cancer" biorxiv.org/content/10.64898… Abstract: "There is strong evidence of tumors manipulating their resting membrane potential (Vmem). While most fully-differentiated cells have a Vmem of roughly -70mV, tumor cells are generally depolarized, with Vmem ≈-30mV, which more closely resembles the Vmem of stem cells. This is often believed to serve the purpose of accelerating the cell cycle and hence advantaging tumor proliferation. But when the tumor becomes invasive, its cells sometimes revert to a hyperpolarized Vmem with no obvious reason why. Separately, it is well accepted that solid tumors that are not yet invasive greatly underexpress connexins relative to healthy tissue; connexins, for our purpose, form gap junctions (GJs), small connecting tubes between nearby cells. Tumors that are invasive, by contrast, overexpress connexins. There is very little explanation for the paradox that connexins are first underexpressed and then overexpressed. However, it has long been known that Vmem electrically gates GJs; specifically, that homotypic GJs conduct best when the two cells they connect have a similar Vmem. Our in-silico model results explain this phenomenon, showing that when considered together, tumors' electrical and connexin-expression behaviors form a unified and effective strategy to control communication between the tumor and its healthy neighbor cells. This has implications for the emerging field of cancer bioelectrics, potentially leading to more precisely-targeted therapies."
