A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently.

Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.
Graphs showing 25 years of budgets for the National Institute of Health, NASA, and the NSF. In all cases, the proposed budget for next year is far, far below any year of the previous quarter century.

Does neural computation feel like something? In our new paper, we explore a paradox: if you replay all the neural activity of a brain—every spike, every synapse—does it recreate conscious experience?

Episode #28 in #TheoreticalNeurosciencePodcast: On whole-cell modeling of bacteria – with Markus Covert

theoreticalneuroscience.no/thn28

In 2020 a model of E. coli with 10000 equations and 19000 parameters was presented by the guest.
How are such models made?

Delighted to join the Royal Society of London for Improving Natural Knowledge! It's been in the news since 1660, and more so lately. Grateful to all my collaborators over the years.

This is completely false. Even the largest university endowment cannot sustain a large-scale scientific research enterprise.

In my 25 years at Princeton, the most monumental fund drive for research raised a total of $325M. Federal research here costs $200M per year, every year.

Linking function and structure at scale with X-rays - and several times over. Massive congratulations to the team ‪@yuxinzhang.bsky.social‬, @carlesbosch.bsky.social, @apacureanu.bsky.social @esrf.fr, @crick.ac.uk and all our collaborators.

My PhD project is out as a preprint!
We combined 2P and synchrotron X-ray to understand mouse olfactory bulb circuits, linking physiology to structure in 3 animals!
