Global and local nature of cortical slow waves:
www.cell.com/iscience/ful...

In brief, we explored in silico how cortical slow waves are shaped by both external inputs and intrinsic properties of neuronal populations.

🔥A new study led by @reiglab.bsky.social and @alegrecortes.bsky.social is now published on @cp-iscience.bsky.social 🙌
Researchers reveal how the brain organizes and directs its slowest activity: slow waves 🧠

Preprint -
Excited to present WHOLISTIC, which extends the concept of whole-brain functional imaging to the entire body. Pioneering work by incredibly talented Virginia Ruetten @vmsruetten.bsky.social, this platform reveals whole-organism cellular dynamics in vivo.

Finding correlates of the same signal in different brain areas is not evidence against specialisation, it is evidence for interconnection.

When I flush my toilet, the level in the tank and the flow rate in the supply pipe become perfectly correlated. Yet these toilet areas have distinct functions.

Scientists in training should be taught the creative scientific process, to gain confidence in their self-efficacy for research and identity as a scientist, & also for greater work satisfaction and a better chance of remaining in science long-term. Join our community at www.night-science.org

I wrote a Comment on neurotheory, and now you can read it!

Some thoughts on where neurotheory has and has not taken root within the neuroscience community, how it has shaped those subfields, and where we theorists might look next for fresh adventures.

We should always take seriously where computational descriptions fail, as it tells us something about where the current boundaries of what we can describe in language lie

1. The philosophy of science sometimes gets an unearned reputation as a purely academic exercise that offers little by way of concrete tools for advancing research.

This is wrong.

And today, as we grapple with how AI is changing the nature of scientific activity, it's desperately wrong.

Lakatos on Popper isn't half bad
devezer.bsky.social
“Popper seems to cultivate rhetoric deliberately, partly to cover up the weaknesses of his argument and partly, I suppose, for moral reasons, to give the impression that he has an argument when he has none. This is characteristic of his whole life’s work. Most of his famous theses are slogans

🚨New paper🚨

Neural manifolds went from a niche-y word to an ubiquitous term in systems neuro thanks to many interesting findings across fields. But like with any emerging term, people use it very differently.

Here, we clarify our take on the term, and review key findings & challenges rdcu.be/ex8hW

We sequentially manipulated the glutamatergic and gabaergic currents in our model, as well as the outward rectification currents. We characterized how they impacted the SWA, the influence of long-range connections, and if the changes remained local.

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!

I believe at this time we can afford more nuance and precision than this. Most null results are uninformative because most experiments are uninformative because we use NHST to replace the scientific process. We can't keep avoiding the root problem forever. Also the focus on efficiency is jarring.

Hot take: Grid cells didn't evolve for spatial navigation, they evolved to play chess
