Why I left academia and neuroscience Don't worry, this isn't yet another story of rage-quitting.

A rather 'unique' paper from our lab is online in @cp-cellreports.bsky.social now. Unique in the sense that I don't think anyone else will be rushing to optotag cortical interneurons in the early postnatal brain... because it is nigh on impossible!

How is valence computed in the brain? Check out our new preprint about a single cell that integrates excitatory and inhibitory input across modalities according to valence and impacts behavioral decisions. An exciting collaboration across many labs. Enjoy reading!

This rule would have meant I couldn't do my Ph.D. in America.

I did do it in America. Became a professor. 12 thriving U.S. labs are now headed by trainees from my research lab. Like me, they are all working hard to enrich American knowledge and society.

With this self-harming rule, none of that.

🚨We believe this is a major step forward in how we study hippocampus function in healthy humans.

Using novel behavioral tasks, fMRI, RL & RNN modeling, and transcranial ultrasound stimulation (TUS), we demonstrate the causal role of hippocampus in relational structure learning.

1/3) This may be a very important paper, it suggests that there are no prediction error encoding neurons in sensory areas of cortex:

Homeostasis can keep population-level responses stable in the face of neural drift and "vanishing neurons"

Nice write up of a paper I'm looking forward to reading but that seems to add more wood to the "populations are more than the sum of their neurons" fire

Let's say you have a journal that isn't worried about protecting an impact factor, so it didn't need to package a million results into a single paper (to maximise citation-to-publication ratio). What would you do? Couple of suggestions below. Others very much appreciated!
