A brain under general anesthesia still registers sound, but anything as elaborate as the meaning or grammar of words was thought to shut down with consciousness. Katlowitz and colleagues had a rare chance to test that. Seven patients undergoing surgery for drug-resistant epilepsy already had hippocampal tissue scheduled for removal, so the team placed high-density probes in it and recorded hundreds of individual neurons while the patients lay fully anesthetized, playing them sequences of tones and, for some, podcast stories. Neurons responded to the tones, and the response to rare, unexpected tones grew over the following minutes, a simple form of learning in a patient with no awareness of it. During the stories, neural activity tracked how frequent each word was and carried information about its meaning and grammatical class. It also held signals that helped predict the upcoming word. The authors conclude that complex sensory processing in the hippocampus can occur without consciousness. The study rests on seven patients, on epileptic tissue already slated for resection, and on one anesthetic, propofol, so sleep, coma and other drugs remain open. Nothing here shows that patients remember any of it after waking, since recall was never tested. The result argues against the stronger version of the assumption, that nothing beyond elementary hearing survives the anesthetic. Fig. 1 from Katlowitz et al. (2026), Nature. CC BY-NC-ND 4.0.

on the flip side - an incredible opportunity for young students to devote themselves to deep understanding and scholarship when the pendulum swings back, they will have acquired discernment and wisdom, and become the most sought after scholars in the next (unpredictable) eras
I’m as AI pilled as anyone, but one of the most tedious parts of AI x Bio right now is almost a complete lack of and almost an active avoidance of scholarship.

It’s not which neurons fire. It’s the geometry of their activity patterns. The piriform cortex doesn’t just store odor “labels.” It continually reshapes that geometry to encode odors. Representational manifolds in olfactory cortex doi.org/10.1016/j.conb.2026.… #neuroscience

Many feel that AI is coming for neuroscience the way it is for math, but I don't think so. To begin with, math has well-defined problems, an extremely mature tradition of exposition, and an immense and reliable literature. Neuroscience, in fact most of the life sciences, has none of these. Where a life-science problem is well-defined, as in structural biology, AI can already dominate. Systems neuroscience has largely failed to pose comparably well-defined scientific problems. Questions of the form “what is the neural basis of X,” where X is an ordinary-language concept (e.g. attention, consciousness, reward, aversion), are not scientific problems. They are just transplanted philosophy. Feed such questions to an AI and it's garbage in garbage out. It's hard even to write a useful prompt. Generating real problems in systems neuroscience would require careful observation and experimentation. A solid finding, e.g. properties of head-direction neurons, can supply material for modeling or reasoning. But such findings constitute only a tiny fraction of what's needed. I think people generally overestimate the power of pure reasoning to solve scientific problems. Reasoning requires material to work with. You need to start with the right premise. In mathematics that material is already abundant and clean; in neuroscience it is not.

Extreme actions historically lead to more extreme backlash. On what time scale will the pendulum swing back to humanity valuing deep thought, artistry, scholarship, and craftsmanship in writing once again? Paper books and in-person custom storefronts already en vogue

Fantastic article on Canuck memory legend Karim Nader by Samia Madwar. Karim’s 2000 reconsolidation paper was a game changer, reorienting neuroscientific studies towards a more reconstructivist view of memory. thewalrus.ca/karim-nader/

Very excited to share the most important discovery of my career yet: your brain switches between a conscious and an unconscious mode ~15 times every second. Consciousness may depend not on where in the brain activity occurs but when. Find out more below. bit.ly/3WvA6di
1/ We discovered something totally unexpected about the neural structure of consciousness that overturns decades of thinking on its biological basis and brings us significantly closer to the recipe for generating conscious awareness.

In 2000, neuroscientist Karim Nader made a groundbreaking discovery that changed the field forever. When a long-term memory is retrieved, he found, it temporarily becomes unstable, prone to revision or erasure. Now, Nader is facing his own cognitive decline. But the legacy of his memory work continues. thewalrus.ca/karim-nader/
