✨ New preprint ✨ What if we could watch AND control thousands of individual neurons in behaving mice—with stable access over months? 🧠⚡ Our work introduces transgenic all-optical tools that make this possible - and a resulting surprising discovery! 🔭💡

Our paper on 'mini analysis' is now published in @jphysiol.bsky.social
If you are recording mPSCs or sPSCs, I hope this helps with analysis. Interpretation of these datasets is not as easy as it seems..!
Happy to discuss if you are interested

Does predictive coding work in SPACE or in TIME? Most neuroscientists assume TIME, i.e. neurons predict their future sensory inputs. We show that in visual cortex predictive coding actually works across SPACE, just like the original Rao+Ballard theory #neuroscience

We previously showed that specific hypothalamic neurons get more and more activated by each bite of food until they put a brake on homeostatic feeding. Here, we find that this brake is already on at the start of a meal in obese mice on a high-fat diet.

Congrats to Marta, Stephen and the whole team!

Like every year, our lab plans to attend the @sfn.org meeting in the US. But is it safe to go? This scientist was sent back (as confirmed by @lemonde.fr, no less). Other visitors were recently detained by ICE goons for days. It feels risky. See y'all at FENS in Barcelona? www.fens.org

Sadly, it’s time to revive this 2017 TIME cover.

delighted to share our work revealing a new type of excitatory hippocampal neuron we call the "ovoid cell", which has really exquisite properties relative to adjacent pyramidal cells! superb work of first-author @adriennekinman.bsky.social and many others in the lab

A little challenge for neuro/cog sci (/psych/comp-sci/bio/philosophy!) blueys:

How would you define "cognition"?

OK If we are moving to Bluesky I am rescuing my favourite ever twitter thread (Jan 2019).

The renamed:

Bluesky-sized history of neuroscience (biased by my interests)

Together with some friends we built an optical Brain Machine Interface to see if cortical activity (PPC) can control behaviour in real time, without animals having to learn to use it. Here's what happened:

In collaboration with Reuben Saunders, @jswlab.bsky.social, and Xiaowei Zhuang, we are very excited to release Perturb-Multi: a platform for pooled multimodal genetic screens in intact mammalian tissue.

Check it out!
