New preprint!

"Non-commitment in mental imagery is distinct from perceptual inattention, and supports hierarchical scene construction"

(by Li, Hammond, & me)

link: doi.org/10.31234/osf...

-- the title's a bit of a mouthful, but the nice thing is that it's a pretty decent summary

Identification of brain-like complex information architectures in embryonic tissue of Xenopus laevis organoids Understanding how populations of cells collectively coordinate activity to produce the complex structures and behaviors that characterize multicellular organisms, and which coordinated activities, ...

New paper!
This one is going to raise some eyebrows, so I want to explain the details before people get all worked-up about the title.

There is no need to simulate multiple alternatives according to an internal model and then select one in order to navigate the environment. F&M articulate their view of perceptual consciousness in terms of this kind of implicit model-based planning, which we think does not exist. (4/7)

Facial expressions in mice reveal latent cognitive variables and their neural correlates - Nature Neuroscience The face reveals more than just emotion. Cazettes, Reato and colleagues show that subtle facial movements reveal hidden cognitive states, reflecting the brain’s ongoing computations and offering a noninvasive window into unexpressed thoughts and decisions.

🐭 Mouse faces reveal hidden thoughts

Researchers found that subtle facial expressions in mice reflect not only their current decisions but also unexpressed cognitive states, offering a new window into brain activity.

What does postdiction show about the speed of consciousness? In this forth. piece in BBS, I respond to @smfleming.bsky.social + @matthiasmichel.bsky.social's claim that postdiction shows consciousness is slow -- too slow for its purpose to be online action guidance. 1/3 philpapers.org/rec/PHIPAT-14

Arousal as a universal embedding for spatiotemporal brain dynamics - Nature Reframing of arousal as a latent dynamical system can reconstruct multidimensional measurements of large-scale spatiotemporal brain dynamics on the timescale of seconds in mice.

This one looks intriguing. Arousal "embedding" whole-brain dynamics. 🤯

Wta? Mind you I got an AI summary that insisted people who had been awarded PhDs were more likely to get Alzheimer’s. Perplexed, I looked up the original. It defined PHD as primary headache disorder. The AI took the statistically more likely abbreviation and came up with its idiotic response. Sigh!

Proofs are in for my paper. The copy editor asks me to provide the given name for the reference to Aristotle. Amazing.
