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.

this is a wonderful overview and very exciting. Great work
Yesterday, @ofgulban.bsky.social gave a great talk about efficient imaging of small veins.
It was inspiring. Impressive how much information is there waiting to be harvested.

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.

After 13 years in the US, I’ve made the difficult decision to leave. Having packed up everything and rethought about priorities, rather painstakingly, while I’m sad to leave the life I’ve made here, I’m also relieved that I won’t have to plan my life around immigration policies anymore.

This this and this ! Also funders don’t get it either many times.
Institutions want us to engage in collaborative research, but they don't appreciate the time it takes. Yesterday a senior leader was stunned to learn that it takes >20 hours a week to manage one of my grants even with an amazing staff of 3. Six institutions, 95 people. It doesn't run itself.

Very excited that the clinical trial results for our PRIMA retinal prosthesis are published today in the New England Journal of Medicine! This is the first time that patients who are blind due to photoreceptor loss have been able to intuitively see again.

Neuroscientists might be forgiven for thinking that they can suction their way back to trust. They have rarely faced opposition to their science. But they should look harder at histories of (say) evolutionary biology vs creationism, climate science vs fossil fuels, vaccines vs hesitancy.

Today, after two years, I can finally remove the yellow ribbon from my profile. A huge sense of relief with an almost unbearable sadness for everything in between.
