I entirely agree.

Research in rodents has enabled remarkable technical advances and deepened our understanding of brainstem circuits and general brain physiology.

However, only NHPs possess cognitive, visual, and motor faculties necessary to advance human-relevant systems neuroscience.
Research in primate brains has been essential for the development of brain-computer interfaces and artificial neural networks. New funding and policy changes put future such advances at risk, write Cory Miller, @movshon.bsky.social and Doris Tsao.

Fear, monkeys, and institutional courage
When news broke of an explosion inside Harvard’s neurobiology building early Saturday morning, every scientist who works with monkeys felt it—an involuntary jolt, a spike of cortisol, the silent thought: what if it had been us? Neither animals nor people were hurt, thankfully. It doesn’t appear to have been an attack. But it didn’t matter. For those of us who work with monkeys, the fear is always near the surface.

Let's recap:

Everything* is everywhere**

* Except language, motor, memory, facial recognition, spatial perception, ...

** Except white matter, human brains, or anything else that is not a mouse brain
How do you deal with the confound of white matter damage when interpreting natural experiments?

I see a lot of talk on here about how we should avoid
"x does y" talk because the brain is "a dynamic, reverberant, reciprocally interconnected system".
But this does not follow.

I think the church of everything is everywhere should check tumor removal surgeries. They all start by making sure they won't remove a specific function when removing a specific region. Can you guess how they do it?

Amidst everything, the lab's first preprint is out! It's just a methods paper, no scientific results (yet!), but it's still great to see it all pulled together. We hope that these open-source behavioral tools will be useful for others!
