New pre-print from a collaboration led by Herrick Fung: In four out of five manipulations of difficulty, confidence does not show the still widely expected folded X-pattern.

Excited to see this now out in the world! We identify a computational basis for how persistent underconfidence is maintained in the face of intact performance, finding that it is grounded in impaired updating of global self-beliefs from local metacognition www.nature.com/articles/s41... 1/N

I asked AI to design a T-shirt for the new MIT Consciousness Club. It couldn't even spell "consciousness" right - and it requires the energy of a nuclear plant. Brains aren’t digital or just connections. Brains are analog computers. There, I said it. #neuroscience

Sensory inputs trigger a fast-traveling wave, followed by a slower wave carrying top-down info (value/choice). The late wave reactivates ensembles in superficial cortical layers. Touch-evoked traveling waves establish a translaminar spacetime code www.science.org/doi/full/10.... #neuroscience

It's finally out! Visual experience orthogonalizes visual cortical responses Training in a visual task changes V1 tuning curves in odd ways. This effect is explained by a simple convex transformation. It orthogonalizes the population, making it easier to decode. 10.1016/j.celrep.2025.115235

osf.io/preprints/ps... nice article, on why we may be totally wrong about aphantasia = imagery blindsight but i'm not sure i agree that for imagery representations to be perception-like, they need to be cross-decodable w/ normal perception. the brain can multiplex two sets of iconic signals 🧠📈

An interesting response to our recent paper on aphantasia as unconscious imagery: osf.io/preprints/ps.... Not sure I agree that a necessary criterion for visual format of imagery is imagery/perception cross-decodability. Here's our paper, itself a commentary on Zeman: www.cell.com/trends/cogni....

Clever study that explores the debate between those who claim that color categories are 'innate' and those who argue that they are dependent on language. It turns out that monkeys, unlike humans, do not have consensus color categories, suggesting cognitive mechanisms such as language are required.🧪🧠

We value things differently depending on the situation. A fascinating paper shows that the hippocampus feeds contextual information to the prefrontal cortex by altering theta wave phase alignment, enabling the PFC to adjust value judgments accordingly. www.nature.com/articles/s41... #neuroscience
