I'm thrilled to share the published version of our paper, now officially out in Neuron! Read it here: authors.elsevier.com/c/1no8J3BtfH... One updated highlight: with new analyses we now show how functionally-defined groups of neurons putatively overlap with molecular cell types in LPBN

We're excited to present EASI-PASS! We can record the activity of many neurons, and separately, the expression of many genes. A natural next step for the field is to link these two types of information. 🧵👇 1/n

I always assumed that brain function had to line up with cytoarchitectonics. It turns out I was wrong. Human cortex, especially PFC, is tiled by chains of functional patches that subdivide and interlink architectonic areas into parallel processing streams. www.biorxiv.org/content/10.6...

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 www.biorxiv.org/cgi/content/...

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!
