State-space trajectories and traveling waves following distraction

Cortical activity shows the ability to recover from distractions. We analyzed neural activity from the prefrontal cortex (PFC) of monkeys performing working memory tasks with mid-memory-delay distract...

This is a demonstration of how a single slice of functional magnetic resonance imaging (fMRI) data is collected. Before this makes any sense, you will need to understand…

well a part a very few descent outlets, their summary is crap anyway AI or not

M.J. Crockett @mjcrockett.bsky.social · 20d

Glad Science collected this data (though the results are entirely unsurprising). GenAI cannot accurately summarize scientific papers, sacrificing accuracy for simplicity.

And shame on publishers who are pushing genAI summaries on readers. Great way to accelerate an epistemic apocalypse.

Launched in 2023, Imaging Neuroscience is now firmly established, with full indexing (PubMed, etc.) and 700 papers to date.

We're very happy to announce that we are able to reduce the APC to $1400.

Huge thanks to all authors, reviewers, editorial team+board, and MIT Press.

- Different BLAS/LAPACK implementations
- Threading changes summation order (round-off)
- MKL/Accelerate/OpenBLAS can use SIMD/FMA and architecture-specific kernels.
- libm differences (exp, log, trig, etc) come from the OS
- compiler stuff affects rounding
- RNGkind() floating-point ops can diverge

computational reproducibility -- since you work with R, you may want to mention numerical accuracy, tiny differences are expected with OS and OS versions

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!
