And yet there are plenty of “legitimate” scientists that voluntarily go on @hubermanlab.com podcast implicitly promoting exactly this grift!

Cell types: encoding the brain's BIOS Inferring the structure of primary rewards from connectomics

What are cell types good for, computationally? Encoding innate behavior! In this 2-parter, I break down the relationship between cell types—which I had, in years prior, dismissed as mere implementation detail—and computation. I changed my mind!

Lack of reviewers threatens robustness of neuroscience literature Simple math suggests that small groups of scientists can significantly bias peer review.

Broad peer review is crucial for a healthy scientific literature, but neuroscientists turn down review requests too often. Simple math suggests that small groups of scientists can significantly bias the literature, writes @jvoigts.bsky.social.

The Chinese University of Hong Kong is searching for an assistant professor in AI Humanities. Application deadline March 29.

my employer is restricting my access to all 2FA systems until i re-watch videos abt "smishing" (SMS-phishing) & social engineering.

same videos every year. no "test out" option. how much $$ is wasted? $50/hr (avg across provosts, student workers) x 1 hr x 34k faculty/staff = $1.7M wasted annually.

The inferred value of unchosen options spreads to related items in memory Counterfactual thinking — considering what could have come of choosing the other path — can facilitate inference. Previous studies have demonstrated t…

📢New paper out today in @cognitionjournal.bsky.social!

Does the value of an unchosen option — inferred through counterfactual reasoning — spread to related items in memory, similar to how the value of a chosen option — acquired through direct experience — does?

In short, yes!

Monitoring Visual Cortex through Brain-Computer Interface Brain-computer interfaces (BCIs) are devices that allow users to interact with computers and other devices using their brainwaves. BCIs can be used to monitor the visual cortex, the part of the brain that is responsible for processing visual information. One way to monitor the visual cortex using a

This 3-day interdisciplinary conference aims to consolidate current knowledge and draw a future plan for aphantasia research.

New lab paper in #ScienceAdvances: we identify a modality-common selective-attention signal in noncholinergic #BasalForebrain (BF) “bursting” neurons, distinct from the modality-specific attention signals typically described in corticothalamic circuits. 1/n

A half-century old question may have its final answer. Using high-resolution #Mini2P microscopes, we find no evidence of local topography in #PlaceCells. Place fields of neighbouring cells are no more similar than those of randomly selected cells. 🧠🗺️ Out now in @pnas.org www.pnas.org/doi/10.1073/...

tl;dr: we show that using human-brain-like feedback/anatomy in a deep RNN leads to human-like visual biases!

Pavlov would have been shocked and stoked by this study!

It meticulously shows that what matters most for cue-reward learning is the duration between rewards: the longer this duration, the fewer the number of trials needed for behavioral and DA learning

In y/n detection tasks, the internal signal and noise distributions have unequal variance. Instead of using d', we should be using dₐ. dₐ is usually estimated from confidence ratings, but this paper shows (in visual tasks) that it's possible to get dₐ from reaction times. Good news!👏 Will surely try

CARTOON OF THE DAY 😕

(From @andertoon.bsky.social )

a while back i threatened to share this. finally online

for detection tasks we often systematically estimates sensitivity wrong. we need to control for unequal variance in models, but we often don't coz it needs extra data

now there's a virtually 'free' way to do it

www.cell.com/iscience/pdf...

clarification: i meant the book is partly based on interviews etc. not that Ned wrote the review based on those. (bad grammar)

i guess perhaps the graphics artists / copyeditor modified their submitted figure, and they didn't check the proof? i hope that's the case. but not sure.

the journal is very high profile too. IF > 17

fair point. but Pam Pondi's name is trending now, and maybe more impactful than Pollan. if she has a theory of consciousness are we supposed to care too?

but i see what you mean. cuts both ways. in the so-called 'science' of consciousness it has just gone too far, perhaps.
