Consciousness research often looks like status hierarchy, not clear science. We’ve seen this before—Marxism taught us to spot it. Nobody learns from history.

Will you be at the Memory Disorders meeting in Toronto. Or in Toronto? Come see Pavlov’s Dogz, the legendary brain punks you've heard so much about. Friday night at The Pilot. Get yr tix NOW! Pavlov's Dogz Date: Oct 23 • 19:00 eventbrite.ca/e/pavlovs-dogz…

Humanity never learns from history. Now Chalmers plays Lenin in the trade union debate—well-paid nonsense published by Nature. So it goes. #AI #Consciousness

IIT measures a correlate, not a cause of consciousness. Low Φ in AI proves nothing—nobody knows how consciousness is implemented. Don’t confuse correlation with causation.

"What" and "where" in frontal cortex, together again. In this case, in a relational code that ties objects to their arrangement. A Relational Code for Objects in Primate Frontal Cortex doi.org/10.64898/2026.10.17.… #neuroscience

A Relational Code for Objects in Primate Frontal Cortex

When we remember a scene, we recall both the locations of individual objects and their spatial arrangement. Yet, how neurons encode this arrangement alongside individual locations is unknown. In this...

IIT is pseudoscience: brain processes info physically; integrated info ≠ consciousness. Tononi’s Φ explains nothing about subjectivity. #neuroscience #IIT #consciousness

Chalmers pondered: light & sound arrive at different speeds, yet the brain perceives them simultaneously. “Why waste a life on 50-sentence jargon and 'the hard problem'? Dennett: “Reflecting? Occam’s razor says thoughts don't exist. It’s all just neurons.” #philosophicalparables

We struggle to publish in Annals of Urupinsk University; Seth & co. land in Nature arguing AI can't be conscious. Intelligence≠consciousness, silicon≠meat, IIT says no. Reads like human exceptionalism. Tononi's IIT needs no vitalism. nature.com/articles/d41586-0…

Three reasons why AI is not conscious and perhaps never will be

Nature - Large language models can mimic thought and feeling with uncanny skill. But evidence from neuroscience suggests that intelligence alone is not enough for subjective experience.

Preprint author on X claims a neural correlate of consciousness. eLife editor: “proper peer review.” Author: it’s on an archive—anyone can review. Editor: not proper. Irony: eLife’s editorial culture—friends publishing friends—has credibility issues. 🧵 #eLife #PeerReview

Replying to @seemaychou @doristsao @eLife
This is just a market for favour-currying, personal incentives, and attention-grabbing, like twitter, no? I understand that not everything requires actual peer review, but if you claim to have found consciousness, it seems like it might be a good idea.

Is it OK for an MIT professor with own lab to publish 3 review articles in 5 years and no original research? Now that we know that @DMSabatini was innocent it may not be so inappropriate to ask. Would I hurt anyone's feelings? scholar.google.com/citations…

Memories. I demonstrated a hand-based center-out task to Russian collaborators. They implemented it but never published, so it remains up for grabs.

Lebedev: BCIs help paralysis & locked-in syndrome. Typing → Kennedy’s invasive electrodes → Utah arrays for robotic arms. Biocompatibility limits recording. AI drives decoding, feedback & auditory prostheses; Neuralink’s first implant failed in a month. youtu.be/WnoKx3ZH8VI?si=XoXC…

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

Rapid alternation of conscious and suppressed stimulus representations in the primate brain

The neural correlates of consciousness remain elusive [1]. Previous studies found that high-level visual cortex is weakly modulated by conscious perception [2,3], yet a pure signal of conscious...

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.

New preprint: neuronal avalanches—power-law cascades of synchronized activity—occur in awake macaque V1/V4, not just motor cortex. In 1,024-channel data, scaling held >10-fold and survived threshold changes but not shuffling. biorxiv.org/content/10.64898…

Neuronal avalanches in awake macaque V1 and V4

Neuronal avalanches are cascades of synchronised activity whose sizes follow power law. Analyses of avalanches shed light on cortical dynamics operating near a critical point. In awake monkeys,...

Activating 1–16 neurons in awake mouse visual cortex: responses follow a power law (~0.285) as single neurons—no ensemble amplification. The network still decodes who fired. Ensembles convey "who," not "how much." Near criticality, cortex scales input. biorxiv.org/content/10.64898…

Critical scaling of cortical ensembles without cooperative amplification

Cortical neurons are sparsely and weakly connected, motivating the long-standing idea that they must act collectively, as cell assemblies, to exert substantial influence on surrounding networks. Yet...

A first glimpse into the ‘middle’ of brain processing

Work by Moran and Desimone showed that monkeys could focus their attention on different stimuli in their visual field without shifting their gaze.
