A few years ago we dreamed about having an automated system in which our animals could live in and train on any behavioral task 24/7 w/o any human intervention. Today, we are very happy to share the Training Village (TV), an open system that can be used to train mice/rats in almost any task (1/4).
I am very excited to share my first preprint🎉
The pandemic kicked off strongly during the first year of my PhD, and I had to stop the behavioral experiments when mice were starting to understand the task. At the BCB Lab, this showed us that training automation could be a real game changer (🧵1/10)

1/7 Can infants recognise the world around them? 👶🧠 As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

A thousand times yes. You can’t publish 40 papers a year and have thought at all deeply about each one. And you can’t run a massive, impersonal lab and produce happy researchers who want to stay in science. The work and the workers suffer. Do less, better!
Great piece on prioritizing quality over quantity in scientific publication.
For those of us with labs, this necessarily involves shrinking our group size. After I got tenure I started to downsize my lab and have not regretted it one iota. More time for each student & more time to think & write.

I’m going to halve my publication output. You should consider slow science, too
If we don’t slow down, the research enterprise is going to crash, argues Adrian Barnett.

We recently did just that to validate a method to measure functional inter-area interactions, and it worked like a charm (academic.oup.com/nc/article/2...). It also puts the model results appear early in the story (in our case, in fig 3 of a 11-fig paper).
