The "publish or perish" culture must perish. Scientists need time to think.

We just published our Slow Science Manifesto, where we argue that huge changes are needed in the way we fund, publish, and evaluate science.

Tax heavens do not receive enough hate. The rethoric of "oh if you increase taxation, billionaires will leave" only works because tax heavens exist. Treat tax heavens as a threat to democracy. Stop free trade and start heavy sanctions for tax heavens - then let's see who's gonna leave.

1/7 Can infants recognise the world around them? πŸ‘ΆπŸ§  As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

New preprint by @semihaktepe.bsky.social πŸŽ‰

We compare ANOVA/SDT/GLMM for binary judgments in 20 datasets of the truth effect. #lme4

Main conclusion:
"GLMMs are a theoretically sound and practically robust method and thus superior for analyzing binary judgments in social and cognitive psychology.”

I'm curious about how you sync them! Does LSL work with fnirs? @tommasoghi.bsky.social is also interested and might also know!

Do you still need a sticker on the head to test with eyelink? If so, I don't see the advantage over tobii. If not, it boils down to price and tobii with no license is the cheapest option.

I think tobii is the best, connecting with python is very easy (devstart.org/CONTENT/EyeT...), and you can do it even without a license. We don't even buy tobii license, which cuts costs massively. Also, 300Hz are more than enough for gaze and pupil with infants!

The Reward Positivity signals a goal prediction error The Reward Positivity (RewP) is an electroencephalogram (EEG) feature that emerges following performance feedback and is commonly understood to index both positive and negative reward-prediction error (RPE+ and RPEβˆ’, respectively) signals. In contrast to this dominant perspective, we argue that the RewP is an independent EEG feature that selectively responds to positive RPE and is superimposed on a common background signal. We further propose that the RewP signals a goal prediction error: it is elicited by abstract signals instead of by hedonic 'rewards'. This goal prediction error appears to be produced by a critic-like architecture that is associated with the actor–critic framework in reinforcement learning. This perspective emphasizes the role of the RewP in goal attainment and cognitive control as opposed to being a simple indicator of reward receipt.

Super cool work! Do you think we are closer to a diagnosis that is not symptom based, or that we have a better understanding of symptoms?

In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes.

Macron remarks are notable- some quotes: "We have been incredibly naive in entrusting our democratic space to social networks that are controlled either by large American entrepreneurs or large Chinese companies, whose interests are not at all the survival or proper functioning of our democracies."

Incredible study by Raut et al.: by tracking a single measure (pupil size), you can model slow, large-scale dynamics in neuronal calcium, metabolism, and brain blood oxygen through a shared latent space! www.nature.com/articles/s41...

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.
