Terrific example of psychology done rigorously! Well done all; and great to see the outcome of all those people toing and froing outside my office under Dani Ropar’s watchful eye…

Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).

🧠What do random neural networks have in common with the motor cortex? Turns out, a lot! Both exhibit similar low‑dimensional dynamics across sensorimotor tasks.👇🧵

"Researchers recruited to work in the UK have to fund a £1,035 annual immigration health surcharge, which must be paid in full in advance, as well as up to £1,519 in visa fees. For a family of four, the upfront costs can total almost £30,000."

Because we must build good things while we scream about the bad, I have started a "Data for Good" team @data-for-good-team.bsky.social that partners with organizations needing short-term data science help. We have three projects ongoing & will add more as our capacity grows. data-for-good-team.org

We are super happy to announce the third Workshop of Ideas in Neuroscience! We will once again look critically at assumptions of modern neuroscience: what does it mean that the brain encodes information? Is this a useful approach, or a metaphor that blurs our vision?

Useful idea here to talk of “converging evidence” rather than “scientific consensus” Not least because some read “consensus” as a conspiracy to silence alternative voices We’ve other names for similar ideas - Edward Wilson’s “consilience”, “triangulation” - but none so transparent

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

I have a BSc and MSc in Cognitive Science. I think I basically agree with the article, that it’s not really a field, but I do think the crossover of AI-Psychology-Neuroscience-Philosophy is very valuable as the basis for a lot of other things. If nothing else, it produced psychologists who can code!

I know this site only reaches a subset of neuro/ cog professors. If you know a young professor in the area who would benefit from a week of targeted learning about doing good science, good mentoring, networking etc, it would be great if you could forward them: compneurosci.com/Neuro4Pros/i...

There's a strong computational neuroscience track, where you could learn with the best in the field (e.g. Srdjan Ostojic, Alex Cayco-Gajic, Boris Gutkin, @stepalminteri.bsky.social, Valentin Wyart) and the mediocre, too (i.e. yours truly).
