Neocortical long-range inhibition promotes cortical synchrony and sleep - Nature

In mice, a sparse population of sleep-active long-range inhibitory neurons in the neocortex promote widespread cortical synchronization and sleep, revealing a cortical mechanism that co...

If you thought "everything is everywhere" in the brain: inactivations reveal a clear distinction of labor. Sensory areas sense, colliculus promotes eligible actions (!), and prefrontal cortex integrates. The role of superior colliculus in a logistic decision www.biorxiv.org/content/10.6...

Imaging cellular activity across all organs reveals body-wide circuits - Nature

An imaging system developed to record cellular activity throughout the whole body of zebrafish captures cellular organ dynamics and identifies multiple distributed circuits.

doi.org/10.1038/s414... Vision is often modelled with tuned filters, noise and fixed bandwidth limits. But speed, dynamic range and hyperacuity need not be assumed. See how they emerge from real biophysics: quantal sampling, refractory dynamics, cellular motion and synaptic high-frequency jumping.

New idtracker.ai rethinks multi-animal tracking as a representation learning problem to increase accuracy and reduce tracking time

Identification of each animal in a collective becomes possible even when individuals are never all visible simultaneously, enabling faster and more accurate analysis of collective behavior.

Sad to hear that Margaret Boden, pioneer in cognitive science and artificial intelligence, has passed away. Just a few days ago, someone reactivated the post below. I warmly recommend watching the video. Thank you Margaret for founding and shaping our field. www.sussex.ac.uk/broadcast/re...

Obituary: Professor Maggie Boden

The University of Sussex mourns the loss of Professor Margaret (Maggie) Boden, a pioneering figure in cognitive science and artificial intelligence.

Did you all know that Margaret Boden founded the first School of Cognitive and Computing Sciences in 1987. No? Well, now you do 😌 Btw, listen to this great talk by her. I'll be adding this to the resources from our 1st year students in Intro to AI. www.youtube.com/watch?v=wPRA...

URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯 Any lab using @flybase.bsky.social please donate using the link in post below. This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.

Marc Dionne@marcsdionne.bsky.social · last yr.

My lab studies bacterial infections. We spend a lot of time looking at (or for) species-specific genetic and genomic databases for hosts and microbes. FlyBase is the best of all—there is literally no comparison. Its existence is under threat. Please donate. www.philanthropy.cam.ac.uk/give-to-camb...

It took us many years to improve idtracker.ai in both accuracy and tracking time. Here it is.

Had to happen at some point: today, the o1 model solved in one go the PhD thesis of one of the students in the lab. Shall we add the model as a coauthor? Shall I stop having students or shall we work on more complex problems?
