This is a really interesting and important study: www.nature.com/articles/s41... However, isn't it concerning that sweeping conclusions about functional organization of cortex are being reached on the basis of a single task?

Rarely categorical, highly separable representations along the cortical hierarchy - Nature
Cortical circuits prioritize diversity over categorical structure, supporting a computational regime geared towards high-dimensional, highly separable neural representations.

🧵 New preprint led by @bingbrunton.bsky.social, @elliottabe.bsky.social, @lawrencehu.bsky.social We gave a worm brain control of a fly body and it walked What did we learn? Nothing, other than deep reinforcement learning is effective We call it the digital sphinx www.biorxiv.org/content/10.6...

Voxelwise Encoding Models do some things differently from other GLM-related methods because the roots of VEM are in neurophysiology, not psychology. This 2006 paper describes system identification for neurophysiology. Change "neurons" to "voxels" and it all still applies. tinyurl.com/wu-etal-2006

I think that if most young people really knew how much non-science work a scientific career requires, most would not persue it. And I say that as someone with zero teaching and only grant and paper related admin.

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.

I agree with @hakwan.bsky.social that it's great for trainees to hear critical questions at meetings. These have disappeared, especially in the US. Maybe it's the drop in NIH funding rates in the 2000s. People don't want enemies. The worst are the meetings hosted by funders: people just nod & smile.

A sobering assessment of consciousness studies from Hakwan Lau: "the label ’consciousness’ may eventually serve little other function but to signal that the associated studies are subpar and overinterpreted compared to mainstream cognitive neuroscience research"

Per an NIH source: “Discussions with colleagues have suggested that if the universities all come together and raise hell about the delays to funding caused by not holding meetings, that might move the needle. From every state. There are well-funded universities in red states that will be impacted.”

12 years in the making! I remember having long chats with Michael Oliver about this paper in 2012. Those are still some of the most comprehensive V4 recordings out there. So happy this is finally out.

This is largely due to NIH funding. And when you look even further back than that, it is stunning for much improvement there has been in treatment and surviveability.

Recent studies found pronounced neuromodulation in the early visual cortex due to locomotion and spontaneous body movements in mice but not in non-human primates. We reconciled this dichotomy in this new open-access feature review @cp-trendsneuro.bsky.social www.sciencedirect.com/science/arti...

Is the impact of spontaneous movements on early visual cortex species specific?
Recent studies in non-human primates do not find pronounced signals related to the animal’s own body movements in the responses of neurons in the visu…

It is sad to see authors not being able to present their work at #NeurIPS2024 because of visa issues. But some authors went above and beyond. Here is @hadivafaii.bsky.social tele-presenting his work with an impressive setup (ipad, mic, speaker, holder, battery). Well done sir!

I think we need to stop asking about the next generation of scientists and figure out how to retain the current generation of scientists. It take a long time to gain expertise and, in the current system, most of that expertise leaves academic research.
